Description

本発明は、例えば携帯電話機や携帯オーディオプレーヤ等の側面操作用の操作スイッチとして用いられる小形・薄形の横押し型プッシュスイッチに関する。 The present invention relates to a small and thin lateral push type push switch used as an operation switch for side operation of, for example, a mobile phone or a portable audio player.

この種の横押し型プッシュスイッチでは、その小形、薄形を実現するために基板への実装を面実装で行い、可動接点にばね性を持ったドーム状金属板を用いるものが多く、横方向の操作力をその操作方向とは垂直方向に変換してドーム状金属板に伝達し、そのドーム状金属板を押し下げて動作させるようになっている。 Many of these types of side-push type push switches are mounted on the board by surface mounting in order to realize their small size and thin type, and many use a dome-shaped metal plate with springiness as the movable contact. The operating force is converted to a direction perpendicular to the operating direction and transmitted to the dome-shaped metal plate, and the dome-shaped metal plate is pushed down to operate.

このような従来の横押し型プッシュスイッチとしては、特許文献１で示すものが知られており、１枚のドーム状金属板がハウジングの内底面に設置され、押しボタンはハウジングに支持され、ハウジングの側部より突出した操作部の押圧操作に伴いドーム状金属板の動作方向とは垂直方向に案内されて移動する。そして、押しボタンに操作部と一直線上で一体に形成する可撓性を持ったヒンジ部と、ハウジングに取り付くカバーに一体に形成し押しボタンの移動方向の操作力をドーム状金属板の動作方向に変換する傾斜部と、を備え、ヒンジ部の先端が傾斜部上で摺動することで、操作部の押圧操作に伴う押しボタンの移動方向の操作力を押しボタンの移動方向とは垂直方向のドーム状金属板の動作方向に変換している。
特開２００５−１２２９８９号公報 As such a conventional lateral push type push switch, the one shown in Patent Document 1 is known. One dome-shaped metal plate is installed on the inner bottom surface of the housing, and the push button is supported by the housing. In accordance with the pressing operation of the operation portion protruding from the side portion of the dome, the dome-shaped metal plate moves while being guided in a direction perpendicular to the operation direction. The push button is integrally formed with the operation part in a straight line with the operation part, and the cover is attached to the housing. And an operating force in the moving direction of the push button that accompanies the pressing operation of the operating unit is perpendicular to the moving direction of the push button by sliding the tip of the hinge portion on the inclined portion. The direction of movement of the dome-shaped metal plate is converted.
JP 2005-122989 A

上記のように従来の横押し型プッシュスイッチは、横方向の操作力をその操作方向とは垂直方向のドーム状金属板の動作方向に変換する部品（傾斜部）と、その部品をドーム状金属板の動作方向に移動させる部品（ヒンジ部）と、を別体に備えているので、操作力をそのままドーム状金属板に伝達し得ず、それに加えて、ドーム状金属板の略中心部を精度よく押圧し得ないため、ドーム状金属板の良好な動作特性を得ることが難しい。 As described above, the conventional lateral push type push switch has a component (inclined portion) that converts the operation force in the lateral direction to the operation direction of the dome-shaped metal plate in a direction perpendicular to the operation direction, and the component as a dome-shaped metal. Since the component that moves in the movement direction of the plate (hinge) is provided separately, the operating force cannot be transmitted to the dome-shaped metal plate as it is, and in addition, the approximate center of the dome-shaped metal plate Since it cannot press accurately, it is difficult to obtain good operating characteristics of the dome-shaped metal plate.

また、押しボタンに一体に形成されたヒンジ部の先端でドーム状金属板を押し下げるので、ヒンジ部には絶縁性が求められ、導電性の金属は使用できず、耐久性に欠ける面があると共に、特性が実装時の熱で変化（劣化）しバラツキを生じ易い。 In addition, since the dome-shaped metal plate is pushed down by the tip of the hinge part formed integrally with the push button, the hinge part is required to have insulation, and conductive metal cannot be used, and there is a lack of durability. The characteristics are likely to change (deteriorate) due to heat during mounting and cause variations.

また、ヒンジ部は略水平姿勢から撓んで弾性変形しながら下方向に押し下げられて、ドーム状金属板を押し下げ、最終的にドーム状金属板をその設置面に対して傾いた傾斜姿勢でドーム状金属板の動作状態を保持するため、接触信頼性に欠ける面がある。 In addition, the hinge part is bent downward from a substantially horizontal posture and is pushed downward while elastically deforming to push down the dome-shaped metal plate. Finally, the dome-shaped metal plate is tilted with respect to its installation surface in a dome shape. Since the operation state of the metal plate is maintained, there is a surface lacking in contact reliability.

ところで、携帯電話機や携帯オーディオプレーヤ等の小形、薄形化に加え、その多機能化が進む中で、従来の横押し型プッシュスイッチは、１枚のドーム状金属板を用い、１段階で１種類のスイッチ回路を開閉操作する１段動作タイプであるため、２枚のドーム状金属板をその動作方向に２段で備え、２段階で２種類のスイッチ回路を開閉操作する２段動作タイプの横押し型プッシュスイッチが強く求められている。 By the way, in addition to downsizing and thinning of cellular phones and portable audio players, etc., as multi-functionality is progressing, a conventional lateral push type push switch uses a single dome-shaped metal plate and is 1 in one step. Because it is a one-stage operation type that opens and closes various types of switch circuits, it is a two-stage operation type that has two dome-shaped metal plates in two stages in its direction of operation and opens and closes two types of switch circuits in two stages. There is a strong demand for a side push push switch.

しかしながら、２段動作タイプの場合、１段動作タイプよりヒンジ部の動作ストローク（ドーム状金属板の押し下げストローク）が長くなるため、上記のような問題が顕著に現れる。それに加えて、ヒンジ部の動作ストロークを長くするためには、傾斜部を大きくする必要があり、そのことが製品の厚みを厚くするという致命的な問題を生じる。 However, in the case of the two-step operation type, the operation stroke of the hinge portion (the push-down stroke of the dome-shaped metal plate) is longer than that in the one-step operation type, and thus the above-described problem appears remarkably. In addition, in order to lengthen the operation stroke of the hinge portion, it is necessary to enlarge the inclined portion, which causes a fatal problem of increasing the thickness of the product.

本発明は、上記のような問題に鑑みてなされたもので、その第１の目的は、ドーム状金属板の良好な動作特性を得ることができる小形、薄形で高寿命、高接触信頼性の横押し型プッシュスイッチを提供することにある。 The present invention has been made in view of the above problems, and a first object thereof is a small, thin, long life, high contact reliability capable of obtaining good operating characteristics of a dome-shaped metal plate. It is to provide a lateral push type push switch.

また、第２の目的は、ドーム状金属板の良好な動作特性を得ることができる小形、薄形で高寿命、高接触信頼性の２段動作タイプの横押し型プッシュスイッチを提供することにある。 The second object is to provide a small, thin, long-life, high contact reliability, two-stage operation type lateral push type push switch capable of obtaining good operating characteristics of a dome-shaped metal plate. is there.

上記の第１の目的を達成するために本発明の横押し型プッシュスイッチは、押しボタンの操作部が側部より突出すると共に、可動接点にばね性を持ったドーム状金属板を用い、前記操作部の押圧操作に伴う前記押しボタンの移動方向の操作力を前記押しボタンの移動方向とは垂直方向のドーム状金属板の動作方向に変換する横押し型プッシュスイッチであって、前記押しボタンの移動方向の操作力を前記ドーム状金属板の動作方向に変換する傾斜部と、この傾斜部を前記ドーム状金属板の動作方向に移動させる可撓性を持ったヒンジ部と、前記ドーム状金属板を押し下げる押圧部と、を有する押し子を備えたことを特徴とするもので、この構成を採用することにより、操作力をそのままドーム状金属板に伝達し、ドーム状金属板の略中心部を精度よく押圧し、ドーム状金属板の良好な動作特性を得ると共に、ヒンジ部の金属化を可能にし、ヒンジ部の耐久性の向上及び特性の安定化を図る。 In order to achieve the first object described above, a lateral push type push switch of the present invention uses a dome-shaped metal plate having a push button operating portion protruding from a side portion and having a spring property as a movable contact. A lateral push type push switch for converting an operation force in a moving direction of the push button accompanying a pressing operation of an operation unit into an operation direction of a dome-shaped metal plate perpendicular to the moving direction of the push button, the push button An inclined portion that converts the operating force in the moving direction into the moving direction of the dome-shaped metal plate, a flexible hinge portion that moves the inclined portion in the moving direction of the dome-shaped metal plate, and the dome-shaped It is characterized by having a pusher having a pressing part for pushing down the metal plate, and by adopting this configuration, the operating force is transmitted to the dome-shaped metal plate as it is, and the approximate center of the dome-shaped metal plate Part Every well pressed together to obtain a good operating characteristics of the dome shaped metal plate, to allow metallization of the hinge portion, to stabilize the improvement and properties of durability of the hinge portion.

また、前記押し子の押圧部が樹脂で成形され、ヒンジ部が金属板バネで形成されている構成を付加することにより、ヒンジ部の金属化による耐久性の向上及び特性の安定化を実現する。 In addition, by adding a configuration in which the pressing portion of the pusher is formed of resin and the hinge portion is formed of a metal leaf spring, durability is improved and characteristics are stabilized by metallization of the hinge portion. .

また、前記押し子自体に前記傾斜部より緩傾斜の傾斜を持たせている構成を付加することにより、１段動作タイプでは傾斜部を小さくしながら、押し子に必要な動作ストロークを得られるようにし、一方、２段動作タイプでは傾斜部を大きくすることなく、押し子の動作ストロークを長くできるようにする。 Further, by adding a configuration in which the pusher itself has a gentler inclination than the inclined part, the operation stroke required for the pusher can be obtained while reducing the inclined part in the single-stage operation type. On the other hand, in the two-stage operation type, the operation stroke of the pusher can be lengthened without increasing the inclined portion.

また、前記押し子は前記押しボタンの押し込みストローク終端で前記ドーム状金属板の設置面と略平行になる構成を付加することにより、押し子がドーム状金属板の動作状態をその設置面に対して略平行になる姿勢で保持し、高い接触信頼性を得る。 In addition, the pusher adds a configuration that is substantially parallel to the installation surface of the dome-shaped metal plate at the end of the push-button stroke of the push button, so that the operation state of the dome-shaped metal plate with respect to the installation surface is increased. Hold in a nearly parallel posture to obtain high contact reliability.

上記の第２の目的を達成するために本発明の横押し型プッシュスイッチは、上記の第１の目的を達成するための本発明の横押し型プッシュスイッチに、前記ドーム状金属板をその動作方向に２段で設置したことを特徴とするもので、製品の厚みを厚くすることなく、２段動作タイプの横押し型プッシュスイッチを得る。 In order to achieve the second object described above, the lateral push-type push switch of the present invention is the same as the lateral push-type push switch of the present invention for achieving the first object. It is characterized in that it is installed in two stages in the direction, and a two-stage operation type lateral push type push switch is obtained without increasing the thickness of the product.

Note that the inclined portion 11 and the pressing portion 13 can be prevented from rotating by, for example, bonding the flat rectangular bottom surface of the inclined portion 11 and the upper surface of the hinge portion 12 with an adhesive.

そして、押し子１４は、ヒンジ部１２の固定端部とその両側に突出されて形成されたコ字状の係止部１２ａが、ハウジング５の切り欠き５ｂを形成した側壁と段付き凹部５ａの間にある内底面と、その面と対向するガイド体９のベース板部９ａの中間辺部外底面との間に挟み込まれて固定されて、ヒンジ部１２が片持ちで支持される。これにより、傾斜部１１が、傾斜角度θを持ったヒンジ部１２によって、押しボタン１０の基板部１０ａの内側に配置され、傾斜部１１の頂部より一側にあり、押しボタン１０の押し込み方向に向かって上り傾斜となる傾斜面１１ａが、押しボタン１０の基板部１０ａの中間辺部中央内側面でなる押し子押し下げ部１０ｄと対向すると共に、押圧部１３が、第１ドーム状金属板６の上に配置され、押圧部１３の下端略中心部が、第１ドーム状金属板６の上面略中心部に当接している。また、傾斜部１１と押圧部１３が片持ち支持のヒンジ部１２によって第１ドーム状金属板６とカバー１５との間に上下に揺動自在に支持している。なお、ヒンジ部１２の固定端部とその両側に突出されて形成されたコ字状の係止部１２ａを挟み込む二面のうちの何れか一方の面、つまり、ハウジング５の切り欠き５ｂを形成した側壁と段付き凹部５ａの間にある内底面、或いは、ガイド体９のベース板部９ａの中間辺部外底面に、ヒンジ部１２の板厚分の深さを有し、ヒンジ部１２の固定端部とその両側に突出されて形成されたコ字状の係止部１２ａを埋め込む図示しない溝を形成することで、コ字状の係止部１２ａの内側にハウジング５或いはガイド体９の樹脂が嵌り込み、押し子１４の位置決めを行うことができる。この際、ヒンジ部１２とハウジング５及びガイド体９との接合面を接着剤により接着することもできる。 The pusher 14 includes a fixed end portion of the hinge portion 12 and a U-shaped locking portion 12a formed to protrude from both sides of the side wall and the stepped recess portion 5a. The hinge portion 12 is supported in a cantilever manner by being sandwiched and fixed between the inner bottom surface in between and the bottom surface of the intermediate side portion of the base plate portion 9a of the guide body 9 facing the surface. Accordingly, the inclined portion 11 is arranged inside the substrate portion 10a of the push button 10 by the hinge portion 12 having the inclination angle θ, and is located on one side from the top of the inclined portion 11, and in the pushing direction of the push button 10. An inclined surface 11 a that is inclined upward is opposed to a pusher pressing portion 10 d that is an inner side surface of the intermediate side portion of the substrate portion 10 a of the push button 10, and the pressing portion 13 is formed on the first dome-shaped metal plate 6. The upper center of the pressing portion 13 is in contact with the upper surface of the first dome-shaped metal plate 6. Further, the inclined portion 11 and the pressing portion 13 are supported by the hinge portion 12 which is cantilevered so as to be swingable up and down between the first dome-shaped metal plate 6 and the cover 15. It should be noted that one of the two surfaces sandwiching the fixed end portion of the hinge portion 12 and the U-shaped locking portion 12a formed to protrude on both sides thereof, that is, the notch 5b of the housing 5 is formed. The inner bottom surface between the side wall and the stepped recess 5a or the outer bottom surface of the intermediate side of the base plate portion 9a of the guide body 9 has a depth corresponding to the plate thickness of the hinge portion 12, By forming a groove (not shown) for embedding the fixed end portion and the U-shaped locking portion 12a formed to protrude on both sides of the fixed end portion, the housing 5 or the guide body 9 is formed inside the U-shaped locking portion 12a. The resin fits in and the pusher 14 can be positioned. At this time, the joint surfaces of the hinge portion 12, the housing 5, and the guide body 9 can be bonded with an adhesive.

また、押し子１４には、それ自体に傾斜角度θを持ったヒンジ部１２によって、傾斜部１１の傾斜面１１ａより緩傾斜の傾斜角度θを持たせている。 Further, the pusher 14 is given a gentler inclination angle θ than the inclined surface 11a of the inclined part 11 by the hinge part 12 having an inclination angle θ itself.

図例では、傾斜部１１を樹脂の押圧部１４側に一体に形成した２ピース構造の押し子１４を示したが、金属板バネからなるヒンジ部１２側に傾斜部１１を一体に形成した２ピース構造の押し子、或いは、傾斜部１１を単品構造で有する３ピース構造の押し子としてもよい。この際、２ピース構造の方が３ピース構造より生産性が高く、コスト面でも有利である。また、これら２ピース或いは３ピース構造の押し子は、インサート成型によって形成することもできる。 In the illustrated example, the pusher 14 having a two-piece structure in which the inclined portion 11 is integrally formed on the resin pressing portion 14 side is shown, but the inclined portion 11 is integrally formed on the hinge portion 12 side made of a metal plate spring. A pusher having a piece structure or a pusher having a three-piece structure having the inclined portion 11 in a single-piece structure may be used. In this case, the two-piece structure has higher productivity than the three-piece structure, and is advantageous in terms of cost. Further, these two-piece or three-piece structure pushers can be formed by insert molding.

カバー１５は、導電性の金属板を打ち抜き及び曲げ加工して形成され、ハウジング５の上面を覆う平板状の上側板１５ａと、この上側板１５ａの４隅に形成され、ハウジング５の突起５ｃと嵌合するカバー位置決め用の切り欠き１５ｂと、上側板１５ａの対向する２側縁から下向きに延出され、下端部をハウジング５の係合爪５ｄに下側から係止させてカバー１５を固定する第１係止部１５ｃと、上側板１５ａの残りの対向する２側縁から下向きに延出され、ハウジング５の係合溝５ｅに嵌合した状態で、下端部をハウジング５の外底面に下側から係止させてカバー１５を固定する第２係止部１５ｄとを備える。 The cover 15 is formed by punching and bending a conductive metal plate. The cover 15 is formed on a flat upper plate 15a that covers the upper surface of the housing 5, and four corners of the upper plate 15a. The cover positioning cutout 15b and the two opposite side edges of the upper plate 15a extend downward, and the cover 15 is fixed by engaging the lower end portion with the engaging claw 5d of the housing 5 from below. The lower end portion of the first locking portion 15c extends downward from the opposite two side edges of the upper plate 15a and engages with the engaging groove 5e of the housing 5, with the lower end portion being on the outer bottom surface of the housing 5. And a second locking portion 15d that locks the cover 15 from below.

図３に示すように、本発明の一実施の形態による横押し型プッシュスイッチ１の組み立ては、ハウジング５の段付き凹部５ａに第１，第２ドーム状金属板６，７を上下２段で設置した後、ハウジング５の切り欠き５ｂを形成した側壁と段付き凹部５ａの間にある内底面の上に、押し子１４のヒンジ部１２の固定端部とその両側に突出されて形成されたコ字状の係止部１２ａを載せ、ハウジング５の段付き凹部５ａの周囲にある内底面の上に固定ストッパ８を一体に形成したガイド体９を配置し、ハウジング５の切り欠き５ｂに押しボタン１０の操作部１０ｂを嵌合すると共に、ガイド体９の切り欠き９ｃに押しボタン１０の可動ストッパ１０ｅを嵌合しながら、押しボタン１０の基板部１０ａをガイド体９のベース板部９ａの上に重ねて配置し、最後に、カバー１５を上方からハウジング５に嵌着して位置決め及び係止させることにより完了する。 As shown in FIG. 3, the side push push switch 1 according to the embodiment of the present invention is assembled by placing the first and second dome-shaped metal plates 6 and 7 in the stepped recess 5a of the housing 5 in two steps. After being installed, it is formed on the inner bottom surface between the side wall in which the notch 5b of the housing 5 is formed and the stepped recess 5a, so as to protrude from the fixed end of the hinge portion 12 of the pusher 14 and both sides thereof. A guide body 9 in which a fixed stopper 8 is integrally formed is placed on the inner bottom surface around the stepped recess 5a of the housing 5 and placed on the notch 5b of the housing 5. While the operating portion 10b of the button 10 is fitted, and the movable stopper 10e of the push button 10 is fitted to the notch 9c of the guide body 9, the substrate portion 10a of the push button 10 is attached to the base plate portion 9a of the guide body 9.

図６は本発明の一実施の形態による横押し型プッシュスイッチの１段目のスイッチ動作後（第１ドーム状金属板動作後）の状態を示す断面図、図７は同横押し型プッシュスイッチの２段目のスイッチ動作後（第２ドーム状金属板動作後）の状態を示す断面図である。図２及び図６，図７に基づいて本発明の一実施の形態による横押し型プッシュスイッチの動作を説明する。 FIG. 6 is a cross-sectional view showing a state after the first-stage switch operation (after the first dome-shaped metal plate operation) of the lateral push-type push switch according to the embodiment of the present invention, and FIG. It is sectional drawing which shows the state after switch operation of the 2nd stage (after 2nd dome-shaped metal plate operation | movement). The operation of the lateral push type push switch according to the embodiment of the present invention will be described with reference to FIGS.

図２は横押し型プッシュスイッチ１の動作前の状態を示し、押しボタン１０を操作しない動作前の状態では、押しボタン１０は、肩部１０ｃがハウジング５の切り欠き５ｂを形成した側壁の切り欠き５ｂの両側にある内面に当接すると共に、可動ストッパ１０ｅがガイド体９のガイド壁部９ｂに形成された切り欠き９ｃ内の左端部に位置し、押し子押し下げ部１０ｄが押し子１４の傾斜部１１の傾斜面１１ａを押圧しない位置に保持されるので、押し子１４は、そのヒンジ部１２に殆ど弾性変形を受けずに略自由状態の傾斜姿勢で保持される。 FIG. 2 shows a state before the lateral push-type push switch 1 is operated. In a state before the push button 10 is not operated, the push button 10 is formed by cutting the side wall where the shoulder 10c forms the notch 5b of the housing 5. The movable stopper 10e is in contact with the inner surface on both sides of the notch 5b, the left end of the notch 9c formed in the guide wall 9b of the guide body 9 is located, and the pusher depressing part 10d is inclined to the pusher 14. Since the inclined surface 11a of the portion 11 is held at a position where the inclined surface 11a is not pressed, the pusher 14 is held in an inclined posture in a substantially free state with almost no elastic deformation at the hinge portion 12.

また、第１ドーム状金属板６と第２ドーム状金属板７とは、それぞれ上向きに膨らんだ状態で離間すると共に、第２ドーム状金属板７は第２選択接点４ａと離間している。ここで、押し子１４の押圧部１３は、第１ドーム状金属板６の上面略中心部で上方向へ押される。これに伴い、押し子１４がその自由状態の傾斜角度θよりややきつい傾斜角度の傾斜姿勢に保持され、押圧部１３の下端略中心部と第１ドーム状金属板６の上面略中心部とが接触保持される。 In addition, the first dome-shaped metal plate 6 and the second dome-shaped metal plate 7 are separated from each other in a state of swelling upward, and the second dome-shaped metal plate 7 is separated from the second selection contact 4a. Here, the pressing portion 13 of the pusher 14 is pressed upward at a substantially central portion on the upper surface of the first dome-shaped metal plate 6. Along with this, the pusher 14 is held in an inclined posture with an inclination angle slightly tighter than the inclination angle θ in its free state, and the lower end substantially central part of the pressing part 13 and the upper surface substantially central part of the first dome-shaped metal plate 6 are formed. Touched and held.

この状態から、押しボタン１０の操作部１０ｂを図２の右方向へ押圧すると、図６に示すように、押し子押し下げ部１０ｄが右方向に移動して押し子１４の傾斜部１１の傾斜面１１ａに接触して右方向に押圧すると共に、傾斜部１１の傾斜面１１ａで摺動する。これに伴い、押し子１４はヒンジ部１２の曲げ部１２ｃで撓んで弾性変形しながら下方向に押し下げられるので、押圧部１３の下端略中心部が第１ドーム状金属板６の上面略中心部を押し下げ操作する。 From this state, when the operation portion 10b of the push button 10 is pressed in the right direction in FIG. 2, the push-down portion 10d moves in the right direction as shown in FIG. 6, and the inclined surface of the inclined portion 11 of the pusher 14 is moved. While touching 11a and pressing rightward, it slides on the inclined surface 11a of the inclined portion 11. Along with this, the pusher 14 is bent downward at the bending portion 12c of the hinge portion 12 and is pushed downward while being elastically deformed, so that the lower end substantially center portion of the pressing portion 13 is substantially center portion of the upper surface of the first dome-shaped metal plate 6. Press down.

これによって、第１ドーム状金属板６は下向きに反転動作して、下側の第２ドーム状金属板７と接触するため、コモン接点２ａと第１選択接点３ａが第１，第２ドーム状金属板６，７を通じて導通して１段目の第１スイッチがオンとなる。 As a result, the first dome-shaped metal plate 6 inverts downward and comes into contact with the lower second dome-shaped metal plate 7, so that the common contact 2a and the first selection contact 3a are formed in the first and second dome shapes. Conducting through the metal plates 6 and 7, the first switch of the first stage is turned on.

この状態から、押しボタン１０の操作部１０ｂをさらに右方向へ押圧すると、図７に示すように、押し子押し下げ部１０ｄはさらに右方向に移動して押し子１４の傾斜部１１の傾斜面１１ａをさらに右方向に押圧すると共に、傾斜部１１の傾斜面１１ａでさらに摺動する。これに伴い、押し子１４はヒンジ部１２の曲げ部１２ｃでさらに撓んで弾性変形しながらさらに下方向に押し下げられるので、この押圧部１３が第１ドーム状金属板６を介して第２ドーム状金属板７の上面略中心部を押し下げ操作する。 From this state, when the operation portion 10b of the push button 10 is further pressed rightward, the pusher push-down portion 10d is further moved rightward as shown in FIG. 7, and the inclined surface 11a of the inclined portion 11 of the pusher 14 is moved. Is further slid on the inclined surface 11 a of the inclined portion 11. Along with this, the pusher 14 is further bent and elastically deformed by the bent portion 12c of the hinge portion 12 and further pushed downward, so that the pressing portion 13 is in the second dome shape via the first dome-shaped metal plate 6. A substantially central portion of the upper surface of the metal plate 7 is pushed down.

これによって、第２ドーム状金属板７は下向きに反転動作して第２選択接点４ａと接触するため、コモン接点２ａと第２選択接点４ａが第１，第２ドーム状金属板６，７を通じて導通して２段目の第２スイッチが１段目の第１スイッチに続いてオンとなる。 As a result, the second dome-shaped metal plate 7 reverses downward and comes into contact with the second selection contact 4a, so that the common contact 2a and the second selection contact 4a pass through the first and second dome-shaped metal plates 6 and 7. The second switch in the second stage is turned on and is turned on following the first switch in the first stage.

この時、押しボタン１０の可動ストッパ１０ｅはガイド体９のガイド壁部９ｂに形成された切り欠き９ｃ内の右端部に移動し、ガイド体９の固定ストッパ８で受け止められ、操作部１０ｂの押圧操作に伴う押しボタン１０の押し込み規制すると共に、第１，第２ドーム状金属板６，７の過剰な押し下げを招く押しボタン１０の過剰な押し込みストローク（オーバーストローク）を制限する。これに伴い、押し子１４が第１，第２ドーム状金属板６，７の動作状態をその設置面に対して略平行になる略水平姿勢で保持する。なお、操作部１０ｂが押圧操作されて第２ドーム状金属板７と第２選択接点４ａが接触している間は第１，第２スイッチのオン状態を保つ。 At this time, the movable stopper 10e of the push button 10 moves to the right end portion in the notch 9c formed in the guide wall portion 9b of the guide body 9, and is received by the fixed stopper 8 of the guide body 9, and is pressed by the operation portion 10b. In addition to restricting the pressing of the push button 10 in accordance with the operation, the excessive pressing stroke (over stroke) of the push button 10 that causes excessive pressing of the first and second dome-shaped metal plates 6 and 7 is limited. Accordingly, the pusher 14 holds the operation state of the first and second dome-shaped metal plates 6 and 7 in a substantially horizontal posture that is substantially parallel to the installation surface. In addition, while the operation part 10b is pressed and the 2nd dome-shaped metal plate 7 and the 2nd selection contact 4a are contacting, the ON state of a 1st, 2nd switch is maintained.

この状態から、操作部１０ｂの押圧操作力を除くと、ヒンジ部１２の弾性復帰力によって押し子１４が図２のスイッチ動作前の状態に復帰すると共に、押しボタン１０も図２のスイッチ動作前の状態に復帰する。この時、押し子１４の復帰に伴い、第１，第２ドーム状金属板６，７がそのばね力によりそれぞれ上向きに反転動作し、第２ドーム状金属板７が第２選択接点４ａより離間して第２スイッチがオフとなり、続いて第１ドーム状金属板６が第２ドーム状金属板７と離間して第１スイッチがオフとなる。 When the pressing force of the operating portion 10b is removed from this state, the pusher 14 returns to the state before the switch operation of FIG. 2 by the elastic return force of the hinge portion 12, and the push button 10 is also before the switch operation of FIG. Return to the state. At this time, as the pusher 14 is returned, the first and second dome-shaped metal plates 6 and 7 are reversed upward by the spring force, and the second dome-shaped metal plate 7 is separated from the second selection contact 4a. Then, the second switch is turned off, and then the first dome-shaped metal plate 6 is separated from the second dome-shaped metal plate 7 and the first switch is turned off.

上記のように、本発明の一実施の形態による横押し型プッシュスイッチ１は、押しボタン１０の操作部１０ｂが側部より突出すると共に、可動接点にばね性を持ったドーム状金属板６，７を用い、前記操作部１０ｂの押圧操作に伴う前記押しボタン１０の移動方向の操作力を前記押しボタン１０の移動方向とは垂直方向のドーム状金属板６，７の動作方向に変換する横押し型プッシュスイッチであって、前記押しボタン１０の移動方向の操作力を前記ドーム状金属板６，７の動作方向に変換する傾斜部１１と、この傾斜部１１を前記ドーム状金属板６，７の動作方向に移動させる可撓性を持ったヒンジ部１２と、前記ドーム状金属板６，７を押し下げる押圧部１３と、を有する押し子１４を備えたことにより、操作力をそのままドーム状金属板６，７に伝達でき、それに加えて、ドーム状金属板６，７の略中心部を精度よく押圧できるので、ドーム状金属板６，７の良好な動作特性を得ることができると共に、ヒンジ部１２の金属化を可能にし、ヒンジ部１２の耐久性の向上及び特性の安定化を図ることができる。 As described above, the lateral push-type push switch 1 according to the embodiment of the present invention includes the dome-shaped metal plate 6 having the operating portion 10b of the push button 10 protruding from the side and having a spring property at the movable contact. 7, the operating force in the moving direction of the push button 10 accompanying the pressing operation of the operating portion 10b is converted into the moving direction of the dome-shaped metal plates 6 and 7 perpendicular to the moving direction of the push button 10. It is a push-type push switch, and an inclined portion 11 that converts an operation force in the moving direction of the push button 10 into an operation direction of the dome-shaped metal plates 6, 7, and the inclined portion 11 is used as the dome-shaped metal plate 6 7 is provided with a pusher 14 having a flexible hinge portion 12 that moves in the direction of movement 7 and a pressing portion 13 that pushes down the dome-shaped metal plates 6 and 7, so that the operating force can be directly applied to the dome shape. metal 6 and 7, and in addition to that, it is possible to accurately press the substantially central portion of the dome-shaped metal plates 6 and 7, so that it is possible to obtain good operating characteristics of the dome-shaped metal plates 6 and 7, and the hinge portion 12 can be metallized, and the durability of the hinge portion 12 can be improved and the characteristics can be stabilized.
