接点本体部４２３は、固定接点部２２の一方の縁部の湾曲面２２１に対向して、本体部４１のベース１１の厚さ方向の移動に伴って、固定接点部２２の縁部に対して接触および開離可能に配置されている。すなわち、接点本体部４２３は、固定接点部２２の一方の縁部の湾曲面２２１に対して、接離方向に交差する方向で接触可能に配置されている。また、第１腕部４２１は、ベース１１の長手方向から見て、ベース１１に接近しかつベース１１に接近するにつれて第２腕部４２２から離れる方向に傾斜して、対向する固定接点部２２の縁部の湾曲部２２１に対して斜めに接触可能に配置されている。 The contact main body portion 423 faces the curved surface 221 of one edge portion of the fixed contact portion 22 and moves relative to the edge portion of the fixed contact portion 22 as the base portion 11 of the main body portion 41 moves in the thickness direction. It is arranged so that it can be contacted and separated. That is, the contact main body 423 is arranged so as to be able to contact the curved surface 221 at one edge of the fixed contact 22 in a direction intersecting the contact / separation direction. The first arm portion 421 is inclined in a direction approaching the base 11 and moving away from the second arm portion 422 as approaching the base 11 when viewed from the longitudinal direction of the base 11, and It arrange | positions so that it can contact diagonally with respect to the curved part 221 of an edge.

第２腕部４２２は、幅狭部４１２の幅方向の他方から固定接点部２２に向かって、可動接点部４２の接離方向に交差する方向に傾斜して延びている。第２腕部４２２の固定接点部２２に対向する面は、固定接点部２２の他方の縁部の湾曲面２２１に対向するように配置されている。すなわち、第２腕部４２２は、本体部４１のベース１１の厚さ方向の移動に伴って、接点本体部４２３とは異なる箇所で、固定接点部２２の縁部に対して接触および開離可能に配置されている。また、第２腕部４２２は、ベース１１の長手方向から見て、ベース１１に接近しかつベース１１に接近するにつれて第１腕部４２１から離れる方向に傾斜して、対向する固定接点部２２の縁部の湾曲部２２１に対して斜めに接触可能に構成されている。 The second arm portion 422 extends from the other side in the width direction of the narrow portion 412 toward the fixed contact portion 22 so as to incline in a direction crossing the contact / separation direction of the movable contact portion 42. The surface of the second arm portion 422 that faces the fixed contact portion 22 is disposed to face the curved surface 221 of the other edge portion of the fixed contact portion 22. That is, the second arm portion 422 can be brought into contact with and separated from the edge portion of the fixed contact portion 22 at a location different from the contact body portion 423 as the base portion 11 of the main body portion 41 moves in the thickness direction. Is arranged. Further, the second arm portion 422 is inclined in a direction approaching the base 11 and moving away from the first arm portion 421 as approaching the base 11 when viewed from the longitudinal direction of the base 11, so It is configured to be able to contact with the curved portion 221 at the edge obliquely.

板ばね部４３は、図２に示すように、本体部４１の延在方向の中心よりも可動接点部４２側に設けられ、可動接点部４２を付勢可能に配置されて、可動接点部４２に対する付勢方向を可動接点部４２が固定接点部２２に接触する接触方向（すなわち、図２のＺ方向下向き）または可動接点部４２が固定接点部２２から開離する開離方向（すなわち、図Ｚ方向上向き）に切り換え可能に構成されている。 As shown in FIG. 2, the leaf spring portion 43 is provided closer to the movable contact portion 42 than the center of the main body portion 41 in the extending direction, and is disposed so as to be able to bias the movable contact portion 42. The direction in which the movable contact 42 comes into contact with the fixed contact 22 (that is, the downward direction in the Z direction in FIG. 2) or the direction in which the movable contact 42 is separated from the fixed contact 22 (ie, the drawing) It is configured to be switchable upward in the Z direction).

詳しくは、板ばね部４３は、ベース１１の長手方向において本体部４１からベース１１に向かって突出する湾曲形状（例えば１つの円弧形状）を有し、本体部４１の幅広部４１１における第２貫通孔４１４のベース１１の第２端部１１４に近い方の第１端部４３１から、ベース１１の長手方向に沿って、可動接点側端子３０の第２壁部３３に向かって延びている。また、板ばね部４３のベース１１の第１端部１１３に近い方の第２端部４３２は、図３に示すように、ベース１１の厚さ方向において、本体部４１の第１壁部３２に対する接続部分４１５よりもベース１１の近くで、第２壁部３３に接続されている。 Specifically, the leaf spring portion 43 has a curved shape (for example, one arc shape) protruding from the main body portion 41 toward the base 11 in the longitudinal direction of the base 11, and the second penetration in the wide portion 411 of the main body portion 41. The hole 414 extends from the first end 431 closer to the second end 114 of the base 11 toward the second wall 33 of the movable contact terminal 30 along the longitudinal direction of the base 11. Further, the second end portion 432 closer to the first end portion 113 of the base 11 of the leaf spring portion 43 has a first wall portion 32 of the main body portion 41 in the thickness direction of the base 11 as shown in FIG. It is connected to the 2nd wall part 33 near the base 11 rather than the connection part 415 with respect to.

板ばね部４３の動作は、詳しくは後述するが、固定接点部２２から開離した状態の可動接触片４０の本体部４１が固定接点部２２に接近するときに、本体部４１が、ベース１１の厚さ方向において、所定の位置（すなわち、付勢方向切換位置）を超えてベース１１に接近すると、板ばね部４３の可動接点部４２に対する付勢方向が開離方向から接触方向に切り替わる。逆に、固定接点部２２に接触した状態の可動接点部４２が固定接点部２２から開離するときに、本体部４１が、ベース１１の厚さ方向において、所定の位置を超えてカバー１２に接近すると、板ばね部４３の可動接点部４２に対する付勢方向が接触方向から開離方向に切り替わる。 The operation of the leaf spring portion 43 will be described in detail later, but when the main body portion 41 of the movable contact piece 40 separated from the fixed contact portion 22 approaches the fixed contact portion 22, the main body portion 41 moves to the base 11. In the thickness direction, when the base 11 is approached beyond a predetermined position (that is, the biasing direction switching position), the biasing direction of the leaf spring portion 43 with respect to the movable contact portion 42 is switched from the separation direction to the contact direction. On the contrary, when the movable contact portion 42 in contact with the fixed contact portion 22 is separated from the fixed contact portion 22, the main body portion 41 exceeds the predetermined position in the thickness direction of the base 11 and covers the cover 12. When approaching, the urging direction of the leaf spring portion 43 against the movable contact portion 42 is switched from the contact direction to the opening direction.

また、可動接触片４０は、弾性部４４を有している。この弾性部４４は、幅狭部４１２の上方（すなわち、ベース１１の厚さ方向のカバー１２側）に配置されかつベース１１の長手方向に延びる板状部４４１と、この板状部４４１のベース１１の第２端部１１４側の端部と本体部４１の幅狭部４１２の先端部とを接続する湾曲部４４２と、板状部４４１のベース１１の第１端部１１３側の端部に設けられた一対の接触部４４３とで構成されている。 The movable contact piece 40 has an elastic portion 44. The elastic portion 44 is disposed above the narrow portion 412 (that is, on the cover 12 side in the thickness direction of the base 11) and extends in the longitudinal direction of the base 11, and the base of the plate-shaped portion 441. 11 at the end of the second end 114 side and the end of the narrow portion 412 of the main body 41 and the end of the plate-like portion 441 on the first end 113 side of the base 11. A pair of contact portions 443 are provided.

板状部４４１は、ベース１１の厚さ方向において、本体部４１の幅狭部４１２よりもベース１１から離れた位置に配置されている。また、一対の接触部４４３は、板状部４４１の幅方向（すなわち、図２のＹ方向）の両端部から相互に対向する方向でかつベース１１から離れる方向に延びている。 The plate-like portion 441 is arranged at a position farther from the base 11 than the narrow portion 412 of the main body portion 41 in the thickness direction of the base 11. Further, the pair of contact portions 443 extend from both ends of the plate-like portion 441 in the width direction (that is, the Y direction in FIG. 2) in a direction facing each other and away from the base 11.

図３に示すように、弾性部４４は、板ばね部４３の付勢力により可動接点部４２が固定接点部２２から開離したときに、一対の接触部４４３がハウジング１０のカバー１２の可動接触片４０に対向する内面１２１に接触して、板状部４４１が本体部４１に接近する方向に弾性変形するように構成されている。 As shown in FIG. 3, when the movable contact portion 42 is separated from the fixed contact portion 22 by the urging force of the leaf spring portion 43, the elastic portion 44 has a pair of contact portions 443 that are movable contacts of the cover 12 of the housing 10. The plate-shaped portion 441 is configured to be elastically deformed in a direction approaching the main body portion 41 in contact with the inner surface 121 facing the piece 40.

なお、前記スイッチ１では、本体部４１、可動接点部４２、板ばね部４３、および、弾性部４４は、一体に形成されている。 In the switch 1, the main body portion 41, the movable contact portion 42, the leaf spring portion 43, and the elastic portion 44 are integrally formed.

操作部５０は、図２に示すように、ベース１１の短手方向に沿って延びる略直方体形状を有している。この操作部５０は、図３に示すように、ベース１１の厚さ方向の下端部５１が、可動接触片４０の本体部４１に対して第１貫通孔４１３と第２貫通孔４１４との間で接触している一方、ベース１１の厚さ方向の上端部５２が、カバー１２の操作孔１４からハウジング１０の外部に露出している。また、操作部５０は、ベース１１の厚さ方向に往復移動可能に配置されている。 As shown in FIG. 2, the operation unit 50 has a substantially rectangular parallelepiped shape extending along the short direction of the base 11. As shown in FIG. 3, the operation unit 50 has a lower end 51 in the thickness direction of the base 11 between the first through hole 413 and the second through hole 414 with respect to the main body 41 of the movable contact piece 40. The upper end 52 in the thickness direction of the base 11 is exposed to the outside of the housing 10 from the operation hole 14 of the cover 12. The operation unit 50 is disposed so as to be reciprocally movable in the thickness direction of the base 11.

次に、図３〜図８を参照して、スイッチ１の動作を説明する。 Next, the operation of the switch 1 will be described with reference to FIGS.

図３および図４に示すように、操作部５０に外力が加えられていない復帰状態のスイッチ１では、可動接触片４０の可動接点部４２が、固定接点部２２から開離した復帰位置に位置して、弾性部４４の一対の接触部４４３が、カバー１２の可動接触片４０に対向する内面１２１に接触している。 As shown in FIGS. 3 and 4, in the switch 1 in a return state in which no external force is applied to the operation unit 50, the movable contact portion 42 of the movable contact piece 40 is positioned at the return position separated from the fixed contact portion 22. The pair of contact portions 443 of the elastic portion 44 are in contact with the inner surface 121 of the cover 12 that faces the movable contact piece 40.

このとき、可動接触片４０の本体部４１は、ベース１１の長手方向における幅狭部４１２側の端部が、板ばね部４３によってベース１１の厚さ方向（すなわち、図３および図４の上下方向）におけるベース１１の第１矩形面１１１から離れる第１方向Ａ１（図３に示す）に付勢され、可動接点部４２が、第１方向Ａ１に付勢されている。また、ベース１１の短手方向から見て、板ばね部４３の第２端部４３２を通りかつベース１１の厚さ方向に延びる仮想直線と交わる本体部４１の中間部分４１７が、板ばね部４３の第２端部４３２よりも上方（すなわち、ベース１１の厚さ方向において、板ばね部４３の第２端部４３２に対してカバー１２側）に位置している。 At this time, the main body portion 41 of the movable contact piece 40 has an end portion on the narrow portion 412 side in the longitudinal direction of the base 11, and the leaf spring portion 43 has a thickness direction of the base 11 (that is, the upper and lower sides in FIGS. 3 and 4). ) In the first direction A1 (shown in FIG. 3) away from the first rectangular surface 111 of the base 11 in the direction), and the movable contact portion 42 is urged in the first direction A1. Further, when viewed from the short side direction of the base 11, an intermediate portion 417 of the main body portion 41 that intersects an imaginary straight line that passes through the second end portion 432 of the leaf spring portion 43 and extends in the thickness direction of the base 11 is formed by Is located above the second end portion 432 (that is, on the cover 12 side with respect to the second end portion 432 of the leaf spring portion 43 in the thickness direction of the base 11).

操作部５０の上端部５２に外力を加えて、ベース１１の厚さ方向におけるベース１１に接近する第２方向Ａ２（図５に示す）に操作部５０を押圧すると、可動接触片４０の本体部４１における操作部５０の下端部５１との接触点４１６近傍の領域が、第２方向Ａ２に弾性変形して、中間部分４１７が板ばね部４３の第２端部４３２に接近する。 When an external force is applied to the upper end 52 of the operation unit 50 and the operation unit 50 is pressed in the second direction A2 (shown in FIG. 5) approaching the base 11 in the thickness direction of the base 11, the main body of the movable contact piece 40. 41, the region near the contact point 416 with the lower end 51 of the operation unit 50 is elastically deformed in the second direction A2, and the intermediate portion 417 approaches the second end 432 of the leaf spring portion 43.

このとき、板ばね部４３の本体部４１に対する付勢力は、中間部分４１７が板ばね部４３の第２端部４３２に接近するにつれて次第に小さくなっていき、図５および図６に示すように、ベース１１の短手方向（図６の左右方向）から見て、中間部分４１７と板ばね部４３の第２端部４３２とが重なる位置（すなわち、付勢方向切換位置）でゼロとなる。 At this time, the urging force of the leaf spring portion 43 against the main body portion 41 gradually decreases as the intermediate portion 417 approaches the second end portion 432 of the leaf spring portion 43, and as shown in FIGS. When viewed from the short direction of the base 11 (left-right direction in FIG. 6), the position becomes zero at the position where the intermediate portion 417 and the second end 432 of the leaf spring portion 43 overlap (that is, the biasing direction switching position).

操作部５０を第２方向Ａ２にさらに押圧すると、可動接触片４０の本体部４１における操作部５０の下端部５１との接触点５１１近傍の領域が、第２方向Ａ２にさらに弾性変形して、図７および図８に示すように、中間部分４１７が、板ばね部４３の第２端部４３２を超えて、ベース１１に接近する。 When the operation unit 50 is further pressed in the second direction A2, the region near the contact point 511 with the lower end 51 of the operation unit 50 in the main body 41 of the movable contact piece 40 is further elastically deformed in the second direction A2, As shown in FIGS. 7 and 8, the intermediate portion 417 approaches the base 11 beyond the second end 432 of the leaf spring portion 43.

このとき、中間部分４１７が板ばね部４３の第２端部４３２を超えてベース１１に接近したと同時に、板ばね部４３の本体部４１に対する付勢方向（すなわち、可動接点部４２に対する付勢方向）が、第１方向Ａ１（すなわち、開離方向）から第２方向Ａ２（すなわち、接触方向）に切り替わる。これにより、可動接点部４２が、第２方向Ａ２に瞬時に移動し、第１腕部４２１の接点本体部４２３が第２方向Ａ２に対して斜め（すなわち、図８の直線Ｌの延在方向）に固定接点部２２の縁部の湾曲面２２１に接触した動作位置に移動して、スイッチ１が動作状態となる。 At this time, the intermediate portion 417 exceeds the second end portion 432 of the leaf spring portion 43 and approaches the base 11, and at the same time, the biasing direction of the leaf spring portion 43 against the main body portion 41 (that is, the biasing force against the movable contact portion 42). Direction) is switched from the first direction A1 (ie, the opening direction) to the second direction A2 (ie, the contact direction). Accordingly, the movable contact portion 42 instantaneously moves in the second direction A2, and the contact main body portion 423 of the first arm portion 421 is inclined with respect to the second direction A2 (that is, the extending direction of the straight line L in FIG. 8). ) To the operating position in contact with the curved surface 221 at the edge of the fixed contact portion 22, and the switch 1 is in the operating state.

その後、操作部５０の第２方向Ａ２への押圧を解除すると、弾性変形していた可動接触片４０の本体部４１が、図７および図８に示す動作位置から図３および図４に示す復帰位置に、操作部５０と共に復帰する。 After that, when the pressing of the operation unit 50 in the second direction A2 is released, the main body 41 of the movable contact piece 40 that has been elastically deformed is returned from the operating position shown in FIGS. 7 and 8 to the state shown in FIGS. It returns to the position together with the operation unit 50.

このとき、本体部４１の復帰力により、板ばね部４３の第２端部４３２よりも下方（すなわち、ベース１１の厚さ方向において、板ばね部４３の第２端部４３２に対してベース１１側）に位置している中間部分４１７が第１方向Ａ１に移動し、板ばね部４３の第２端部４３２を超えてカバー１２に接近したと同時に、板ばね部４３の本体部４１に対する付勢方向（すなわち、可動接点部４２に対する付勢方向）が、第２方向Ａ２（すなわち、接触方向）から第１方向Ａ１（すなわち、開離方向）に切り替わる。これにより、可動接点部４２が第１方向Ａ１に瞬時に移動して固定接点部２２から開離した復帰位置に移動して、スイッチ１が復帰状態となる。 At this time, due to the restoring force of the main body 41, the base 11 is lower than the second end 432 of the leaf spring portion 43 (that is, with respect to the second end 432 of the leaf spring portion 43 in the thickness direction of the base 11). The intermediate portion 417 located on the side) moves in the first direction A1 and approaches the cover 12 beyond the second end 432 of the leaf spring portion 43. At the same time, the leaf spring portion 43 is attached to the main body portion 41. The urging direction (that is, the urging direction with respect to the movable contact portion 42) is switched from the second direction A2 (that is, the contact direction) to the first direction A1 (that is, the opening direction). As a result, the movable contact portion 42 instantaneously moves in the first direction A1 and moves to the return position separated from the fixed contact portion 22, and the switch 1 enters the return state.

すなわち、可動接点部４２が固定接点部２２に対して接触または開離するために、本体部４１の中間部分４１７と板ばね部４３の第２端部４３２とが重なった付勢方向切換位置を過ぎるとき、板ばね部４３の可動接点部４２に対する付勢方向が開離方向から接触方向に切り替わるか、または、接触方向から開離方向に切り替わる。 That is, in order for the movable contact portion 42 to contact or separate from the fixed contact portion 22, the biasing direction switching position where the intermediate portion 417 of the main body portion 41 and the second end portion 432 of the leaf spring portion 43 overlap each other is set. When it passes, the urging | biasing direction with respect to the movable contact part 42 of the leaf | plate spring part 43 switches from a separation direction to a contact direction, or switches from a contact direction to a separation direction.

また、可動接点部４２が固定接点部２２から開離して復帰位置に移動したとき、図３および図４に示すように、弾性部４４の一対の接触部４４３が、ハウジング１０のカバー１２の可動接触片４０に対向する内面１２１に接触して、板状部４４１が本体部４１に接近する方向に弾性変形する。 Further, when the movable contact portion 42 is separated from the fixed contact portion 22 and moved to the return position, the pair of contact portions 443 of the elastic portion 44 are movable of the cover 12 of the housing 10 as shown in FIGS. The plate-shaped part 441 is elastically deformed in a direction approaching the main body part 41 by contacting the inner surface 121 facing the contact piece 40.

前記スイッチ１では、可動接点部４２が、本体部４１から固定接点部２２に向かって接離方向に交差する方向に延びかつ弾性変形可能な腕部としての第１腕部４２１と、第１腕部４２１の固定接点部２２に対向する部分に設けられた接点本体部４２３とを有している。これにより、可動接点部４２の接点本体部４２３が固定接点部２２に衝突したときの衝突音を低減できる。その結果、スイッチの静粛性を高めることができる。 In the switch 1, the movable contact portion 42 extends from the main body portion 41 toward the fixed contact portion 22 in a direction intersecting the contact / separation direction, and a first arm portion 421 serving as an elastically deformable arm portion, and a first arm And a contact main body portion 423 provided at a portion of the portion 421 facing the fixed contact portion 22. Thereby, the collision sound when the contact main-body part 423 of the movable contact part 42 collides with the fixed contact part 22 can be reduced. As a result, the quietness of the switch can be improved.

例えば、図１１に示すように、前記スイッチ１でマウス７０のクリックボタンを構成した場合、可動接点部と固定接点部とが接触方向で衝突するスイッチを用いた場合と比較して、マウス７０のクリック音を約６０％以上低減させることができる。 For example, as shown in FIG. 11, when the click button of the mouse 70 is configured by the switch 1, compared to the case where a switch in which the movable contact portion and the fixed contact portion collide in the contact direction is used, The click sound can be reduced by about 60% or more.

また、可動接点部４２の接点本体部４２３が、固定接点部２２の縁部の湾曲面２２１に対して接触および開離可能に対向して配置されているので、可動接点部が固定接点部に摺動接触するスイッチと比較して、耐久性を高めることができる。 Further, since the contact main body portion 423 of the movable contact portion 42 is disposed so as to be able to contact and separate from the curved surface 221 at the edge of the fixed contact portion 22, the movable contact portion becomes the fixed contact portion. Compared with a switch that is in sliding contact, durability can be improved.

また、第１腕部４２１が、固定接点部２２に接触方向に対して斜めに接触可能に配置されている。これにより、可動接点部４２と固定接点部２２とが衝突したときの衝突音を低減して、静粛性を高めることができる。 Further, the first arm portion 421 is disposed so as to be able to contact the fixed contact portion 22 obliquely with respect to the contact direction. Thereby, the collision sound when the movable contact part 42 and the fixed contact part 22 collide can be reduced, and silence can be improved.

また、付勢部としての板ばね部４３が、可動接触片４０と一体に形成され、本体部４１の可動接点側端子３０に対する接続部分４１５と可動接点部４２との間に配置されている。これにより、例えば、付勢部としてコイルばねを用いたスイッチと比較して、部品点数を減らして、より小型のスイッチ１を提供できる。 Further, a leaf spring portion 43 as an urging portion is formed integrally with the movable contact piece 40 and is disposed between the connection portion 415 for the movable contact side terminal 30 of the main body portion 41 and the movable contact portion 42. Thereby, compared with the switch using a coil spring as an urging | biasing part, the number of parts can be reduced and the smaller switch 1 can be provided, for example.

また、固定接点部２２の縁部に、可動接点部４２の接点本体部４２３に向かって突出した湾曲面２２１が設けられており、可動接点部４２が、湾曲面２２１に対向して配置されている。これにより、可動接点部４２の接点本体部４２３を固定接点部２２の縁部に対して斜めに接触させることができるので、可動接点部４２と固定接点部２２とが接触したときの衝突音を低減して、静粛性を高めることができる。 In addition, a curved surface 221 protruding toward the contact main body 423 of the movable contact portion 42 is provided at the edge of the fixed contact portion 22, and the movable contact portion 42 is disposed so as to face the curved surface 221. Yes. Thereby, since the contact main body part 423 of the movable contact part 42 can be brought into contact with the edge of the fixed contact part 22 at an angle, the collision sound when the movable contact part 42 and the fixed contact part 22 come into contact with each other is generated. It can reduce and can improve quietness.

ここで、固定接点部２２の縁部の湾曲面２２１に加えて、あるいは、固定接点部２２の縁部の湾曲面２２１に代えて、可動接点部４２の接点本体部４２３に、固定接点部２２の縁部に向かって突出した湾曲面を設けてもよい。この場合でも、可動接点部４２と固定接点部２２とが接触したときの衝突音を低減して、静粛性を高めることができる。 Here, in addition to the curved surface 221 at the edge of the fixed contact portion 22 or instead of the curved surface 221 at the edge of the fixed contact portion 22, the fixed contact portion 22 is connected to the contact main body 423 of the movable contact portion 42. You may provide the curved surface which protruded toward the edge part. Even in this case, it is possible to reduce the collision sound when the movable contact portion 42 and the fixed contact portion 22 come into contact with each other, thereby improving the silence.

なお、固定接点部２２の縁部の湾曲面２２１、および、可動接点部４２の接点本体部４２３の固定接点部２２の縁部に向かって突出した湾曲面のいずれも省略して設けない場合（すなわち、固定接点部２２と可動接点部４２とが面で接触する場合）であっても、可動接点部と固定接点部とが接触方向で接触するスイッチと比較して、可動接点部４２と固定接点部２２とが接触したときの衝突音を低減して、静粛性を高めることができる。 Note that neither the curved surface 221 at the edge of the fixed contact portion 22 nor the curved surface protruding toward the edge of the fixed contact portion 22 of the contact main body portion 423 of the movable contact portion 42 is provided. That is, even when the fixed contact portion 22 and the movable contact portion 42 are in contact with each other on the surface, the movable contact portion 42 and the fixed contact portion are fixed as compared with a switch in which the movable contact portion and the fixed contact portion are in contact with each other in the contact direction. It is possible to reduce a collision sound when the contact portion 22 comes into contact with the contact portion 22 and improve silence.

また、可動接点部４２が、本体部４１から固定接点部２２に向かって第１腕部４２１の延在方向に交差する方向に傾斜すると共に、接点本体部４２３とは異なる箇所で、固定接点部２２の縁部２２１に接離方向に対して斜めに接触可能な追加腕部としての第２腕部４２２を有している。前記スイッチ１では、第１腕部４２１および第２腕部４２２は、それぞれ厚さ方向に弾性変形可能であり、かつ、本体部４１に対して対称に設けられているので、接点本体部４２３の固定接点部２２に対する接圧を高めることができる。これにより、チャタリングの発生を抑制することできる。 Further, the movable contact portion 42 is inclined in a direction intersecting the extending direction of the first arm portion 421 from the main body portion 41 toward the fixed contact portion 22, and the fixed contact portion is different from the contact main body portion 423. 22 has a second arm portion 422 as an additional arm portion that can be contacted obliquely with respect to the contact / separation direction. In the switch 1, the first arm portion 421 and the second arm portion 422 are each elastically deformable in the thickness direction and are provided symmetrically with respect to the main body portion 41. The contact pressure with respect to the fixed contact portion 22 can be increased. Thereby, generation | occurrence | production of chattering can be suppressed.

なお、第１腕部４２１および第２腕部４２２は、例えば、第１腕部４２１と第２腕部４２２とが４５度から６０度の角度を成すように構成するのが好ましい。これにより、可動接点部４２と固定接点部２２とが接触したときの衝突音をより確実に低減して、静粛性を高めることができる。 The first arm portion 421 and the second arm portion 422 are preferably configured such that, for example, the first arm portion 421 and the second arm portion 422 form an angle of 45 degrees to 60 degrees. Thereby, the collision sound when the movable contact part 42 and the fixed contact part 22 contact can be reduced more reliably, and silence can be improved.

また、接点本体部４２３は、第１腕部４２１の固定接点部２２に対向する部分に設けられていればよく、第１腕部４２１の固定接点部２２の縁部に対向する部分に設けられている場合に限らない。 Further, the contact main body 423 may be provided at a portion facing the fixed contact portion 22 of the first arm portion 421, and is provided at a portion facing the edge portion of the fixed contact portion 22 of the first arm portion 421. Not limited to that.

また、可動接触片４０が、板ばね部４３の付勢力により可動接点部４２が固定接点部２２から開離したときに、ハウジング１０の可動接触片４０に対向する内面１２１に接触して接離方向に弾性変形する弾性部４４を有している。これにより、可動接点部４２とハウジング１０のカバー１２とが直接接触する場合と比較して、可動接点部４２が固定接点部２２から開離したときに発生する衝突音を低減して、静粛性を高めることができる。 Further, when the movable contact piece 40 is separated from the fixed contact portion 22 by the urging force of the leaf spring portion 43, the movable contact piece 40 comes into contact with and separates from the inner surface 121 of the housing 10 facing the movable contact piece 40. It has an elastic part 44 that is elastically deformed in the direction. As a result, compared with the case where the movable contact portion 42 and the cover 12 of the housing 10 are in direct contact, the collision noise generated when the movable contact portion 42 is separated from the fixed contact portion 22 is reduced, and quietness is achieved. Can be increased.

また、弾性部４４が、可動接触片４０の本体部４１に一体に設けられている。これにより、部品点数を減らして、スイッチ１の組み立てを容易にすることができる。 Further, the elastic portion 44 is provided integrally with the main body portion 41 of the movable contact piece 40. Thereby, the number of parts can be reduced and the assembly of the switch 1 can be facilitated.

なお、弾性部４４は、図１０に示すように、幅狭部４１２の幅方向の両端部から相互に対向する方向でかつベース１１から離れる方向に延びている一対の接触部４４３のみで構成してもよい。この場合、一対の接触部４４３は、板ばね部４３の付勢力により可動接点部４２が固定接点部２２から開離したときに、一対の接触部４４３がハウジング１０のカバー１２の可動接触片４０に対向する内面１２１に接触して、板状部４４１が本体部４１に接近する方向に弾性変形するように構成されている。これにより、弾性部４４を小型化でき、部品の簡素化が図れる。 As shown in FIG. 10, the elastic portion 44 is composed of only a pair of contact portions 443 extending in opposite directions from both ends in the width direction of the narrow portion 412 and away from the base 11. May be. In this case, the pair of contact portions 443 is configured such that the pair of contact portions 443 are movable contact pieces 40 of the cover 12 of the housing 10 when the movable contact portion 42 is separated from the fixed contact portion 22 by the biasing force of the leaf spring portion 43. The plate-like portion 441 is configured to be elastically deformed in a direction approaching the main body portion 41 in contact with the inner surface 121 facing the surface. Thereby, the elastic part 44 can be reduced in size and simplification of components can be achieved.

また、弾性部４４は、可動接触片４０の本体部４１に一体に設けられている場合に限らない。例えば、図１１に示すように、収容部１３のベース１１の第１矩形面１１１上の第２端部１１４側の端部にベース１１の厚さ方向に延びる支持部４４４を設け、この支持部４４４のカバー１２側の端部に、弾性部４４を可動接触片４０とは別体に設けてもよい。すなわち、弾性部４４は、可動接触片４０の開離方向への移動に連動して、板ばね部４３の付勢力により可動接点部４２が固定接点部２２から開離して復帰位置に移動したときに可動接触片４０に接触し、接触方向または開離方向に弾性変形して衝突音を低減する構成であれば、任意の構成を採用することができる。 Further, the elastic portion 44 is not limited to being provided integrally with the main body portion 41 of the movable contact piece 40. For example, as shown in FIG. 11, a support portion 444 extending in the thickness direction of the base 11 is provided at an end portion of the base portion 11 on the first rectangular surface 111 of the housing portion 13 on the second end portion 114 side. The elastic portion 44 may be provided separately from the movable contact piece 40 at an end portion of the 444 on the cover 12 side. That is, the elastic portion 44 is moved when the movable contact portion 42 is separated from the fixed contact portion 22 and moved to the return position by the urging force of the leaf spring portion 43 in conjunction with the movement of the movable contact piece 40 in the opening direction. Any configuration can be adopted as long as it is configured to contact the movable contact piece 40 and elastically deform in the contact direction or the separation direction to reduce the collision sound.

また、弾性部４４は省略することもできる。弾性部４４を省略した場合であっても、可動接点部が固定接点部に衝突したときの接触方向の力を低減させることができるので、スイッチ１の静粛性を高めることはできる。 Further, the elastic portion 44 can be omitted. Even when the elastic portion 44 is omitted, the force in the contact direction when the movable contact portion collides with the fixed contact portion can be reduced, so that the silence of the switch 1 can be improved.

また、弾性部４４に限らず、可動接触片４０の本体部４１、可動接点部４２、および、板ばね部４３についても、それぞれ別体で設けることができる。例えば、付勢部として、板ばね部４３の代わりにコイルばねを用いてもよい。すなわち、本発明は、前記スイッチ１に限らず、可動接点部が、本体部から固定接点部に向かって接離方向に交差する方向に傾斜する腕部と、腕部の固定接点部の縁部に対向する部分に設けられて固定接点部の縁部に接触方向に対して斜めに接触可能な接点本体部とを有することができる任意のスイッチに適用できる。 In addition to the elastic portion 44, the main body portion 41, the movable contact portion 42, and the leaf spring portion 43 of the movable contact piece 40 can be provided separately. For example, a coil spring may be used instead of the leaf spring portion 43 as the urging portion. That is, the present invention is not limited to the switch 1, and the arm part in which the movable contact part is inclined in the direction intersecting the contact / separation direction from the main body part toward the fixed contact part, and the edge part of the fixed contact part of the arm part It can be applied to any switch that can have a contact body portion that is provided at a portion facing the contact portion and that can contact the edge of the fixed contact portion obliquely with respect to the contact direction.
