- a central portion on the upper surface of the movable member 3 constitutes a pressure receiving portion 32 (see FIG. 3). That is, the central portion of the upper surface of the movable member 3 functions as the pressure receiving portion 32 that receives the operating force.
- the movable member 3 is formed in a dome shape that is curved so that the central portion is convex upward. That is, in this embodiment, the movable member 3 is a dome formed from a conductive metal plate.
- Four contact pieces 31 are provided on the outer peripheral edge of the movable member 3 at intervals in the circumferential direction. In a state where the movable member 3 is housed in the recess 210, these contact pieces 31 come into contact with the bottom surface 211 of the recess 210.

That is, when an operating force acts on the upper end portion of the pusher 5 from above, the operating force is transmitted to the pressure receiving portion 32 via the pusher 5 and acts on the pressure receiving portion 32 from above. Thereby, when the pusher 5 is pushed, the pressure receiving part 32 is indirectly operated via the pusher 5.

- the diameter dimension of the extension part 63 is smaller than the width dimension (the dimension in the left-right direction or the front-rear direction) of the base part 62.
- the support portion 6 has a configuration in which the upper end edge of the truncated cone-shaped main portion 61 is connected to the side surface of the pusher 5 and the lower end edge of the main portion 61 is connected to the base portion 62.

- an operating force applied to the pusher 5 a movement amount of the pusher 5.
- FIGS. 6A to 6F show the behavior of the support portion 6 according to the amount of movement of the pusher 5 in the push switch 1 excluding the movable member 3, respectively.
- FIG. 6A shows the state of the support portion 6 when not operated, that is, when the amount of movement of the pusher 5 is zero.
- 6B to 6F respectively show the case where the movement amount of the pusher 5 is 0.2 [mm], 0.4 [mm], 0.6 [mm], and 0.8 [mm].
- the state of the support part 6 in the case of 1.0 [mm] is represented.
- the portion receiving the load is represented by a dot. The larger the dot density, the greater the load, and the smaller the dot density, the smaller the load.
- the main portion 61 is gradually deformed by receiving the operating force (FIG. 6A to FIG. 6).
- the function of transmitting the operating force of the main part 61 to the extension part 63 is not lost. For this reason, until the movement amount of the pusher 5 reaches the first threshold Th ⁇ b> 1, the drag received by the extension 63 from the case 2 is transmitted to the pusher 5 through the main part 61. Therefore, until the movement amount of the pusher 5 reaches the first threshold Th1, the load acting on the pusher 5 from the support portion 6 increases as the movement amount of the pusher 5 increases.
- the force (synthetic vector V3) in the direction orthogonal to the surface of the main portion 61 is the force transmitted from the pusher 5 to the case 2 (first vector V1) and the drag transmitted from the case 2 to the pusher 5 (second This corresponds to the sum of the vector V2).
- first vector V1 the force transmitted from the pusher 5 to the case 2
- second the drag transmitted from the case 2 to the pusher 5
- the main portion 61 is gradually deformed, so that the combined vector V3 increases.
- the magnitude of the combined vector V3 exceeds a predetermined value, the balance between the first vector V1 and the second vector V2 is lost, and the main part 61 is deformed excessively compared with the non-operating state (FIG. 6D to FIG. 6). (See FIG. 6F).
- the function of transmitting the operation force of the main portion 61 to the extension portion 63 is lost.
- the support portion 6 has a shape having the extension portion 63
- the movement of the extension portion 63 is restricted by the inner wall of the recess 210.
- the intermediate portion in the longitudinal direction of the main portion 61 enters the recess 210 and is at a position lower than the lower surface position of the base portion 62.
- the support portion 6 when the movement amount of the pusher 5 reaches the first threshold Th ⁇ b> 1, the drag from the case 2 is hardly transmitted to the pusher 5 through the main portion 61. Therefore, when the movement amount of the pusher 5 reaches the first threshold Th1, the load acting on the pusher 5 from the support portion 6 decreases as the movement amount of the pusher 5 increases. That is, in this embodiment, the increase / decrease of the load which acts on the pusher 5 from the support part 6 is reversed on the boundary of 1st threshold value Th1.

- the bottom load in the second region A2 acts on the operator from the support portion 6 (about 2 [N]), and acts on the operator from the movable member 3 and the pusher 5. It is the sum of the load to be applied (about 1 [N]) and is about 3 [N].
- the magnitude of the difference B1 between the peak load and the bottom load in the second region A2 is about 2 [N].
- the magnitude of the difference B2 between the peak load and the bottom load in the second region A2 is less than 1 [N].

Abstract
Description
本実施形態のプッシュスイッチ1は、図1A及び図1Bに示すように、(第1)固定接点部7を有するケース2と、可動部材3と、押し子5と、支持部6と、を備えている。
以下、本実施形態のプッシュスイッチ1について詳細に説明する。プッシュスイッチ1は、例えば携帯情報端末、車載機器、又は家電機器などの各種の機器の操作部に用いられる。プッシュスイッチ1は、例えばプリント基板に実装された状態で機器の筐体に内蔵される。この場合、筐体においてプッシュスイッチ1に対応する位置には、例えば中間部材として操作釦10が配置される。これにより、操作者が操作釦10を押すことによって、プッシュスイッチ1が操作釦10を介して間接的に操作される。
以下、本実施形態のプッシュスイッチ1の動作について説明する。
まず、プッシュスイッチ1の基本動作について図1A及び図1Bを用いて説明する。操作者がプッシュスイッチ1の押し子5を一定以上の力で押操作すると、押し子5を介して上方から可動部材3の受圧部32に操作力が作用する。すると、受圧部32が下方に押されて、可動部材3が徐々に変形する。そして、可動部材3に作用する操作力の大きさが所定の大きさを超える(言い換えれば、押し子5の移動量が第2閾値Th2を超える)と、図1Bに示すように、可動部材3は勢いよく座屈して大きく変形する。このとき、受圧部32に作用する可動部材3の弾性力が急激に変化する。このような可動部材3の反転動作によって、可動部材3は、例えば図1Bに示すように、中央部(受圧部32)が下向きに凸となるように湾曲したドーム状等に変形する。したがって、プッシュスイッチ1を押操作する操作者には、可動部材3の変形に伴って節度感(クリック感)が与えられる。そして、可動部材3が上記のように変形すると、図1Bに示すように、可動部材3の下面に形成されている可動接点部8が固定接点部7に接触し、接点部4がオンになる。この状態では、第1端子11と第2端子12との間が導通する。
次に、操作者がプッシュスイッチ1の押し子5を押操作する際に、操作者に作用する荷重について図7A~図7Dを用いて説明する。本実施形態のプッシュスイッチ1では、押し子5から操作者に作用する荷重と、押し子5の移動量との相関は、図7Aに示すように、第1領域A1と、第2領域A2と、第3領域A3とで、それぞれ異なる特性を示す。図7A~図7Dの各々において、縦軸は荷重(単位は〔N〕)、横軸は押し子5の移動量(単位は〔mm〕)を表している。
ここで、本実施形態のプッシュスイッチ1では、第2領域A2におけるピーク荷重とボトム荷重との差分B1の大きさが約2〔N〕である。一方、比較例のプッシュスイッチ100では、第2領域A2におけるピーク荷重とボトム荷重との差分B2の大きさが1〔N〕未満である。このため、比較例のプッシュスイッチ100では、本実施形態のプッシュスイッチ1と比較して、操作者に与える節度感(クリック感)が損なわれている。
上述の実施形態は、本開示の様々な実施形態の一つに過ぎない。上述の実施形態は、本開示の目的を達成できれば、設計等に応じて種々の変更が可能である。以下、上述の実施形態の変形例を列挙する。以下に説明する変形例は、適宜組み合わせて適用可能である。
