PUSH SWITCH AND INPUT DEVICE

PROBLEM TO BE SOLVED: To provide a thin push switch of good operation feeling, and to provide an input device.SOLUTION: A push switch includes a thin base plate 10, a support member 50 disposed on the upper side of the base plate 10, a thin plate oscillating member 30 having a base 31 held on the support member 50 and a flat plate drive part 32 concatenated from the base 31 and extending in the direction along the upper surface of the base plate 10, a dome-like spring member 40 giving a reaction force to the downward movement of the drive part 32 and capable of inversion operation, and detection means 20 for detecting the downward movement of the drive part 32. The drive part 32 has a push-in portion 32a for pushing the vertex of the spring member 40, and has an opening 32b capable of avoiding interference with the spring member 40 at a part other than the push-in portion 32a, at a position in the direction separating from at least the base 31 around the push-in portion 32a.SELECTED DRAWING: Figure 1 【課題】薄型で、操作感触の良好なプッシュスイッチおよび入力装置を提供する。【解決手段】薄板状の基台１０と、基台１０の上面側に配設された支持部材５０と、支持部材５０に保持された基部３１および基部３１から連接され基台１０の上面に沿う方向に延在する平板状の駆動部３２を有する薄板状の揺動部材３０と、駆動部３２の下方向への移動に対して反力を与えるとともに反転動作可能なドーム状のバネ部材４０と、駆動部３２の下方向への移動を検出する検出手段２０とを備え、駆動部３２は、バネ部材４０の頂点を押すための押し込み部３２ａを有し、押し込み部３２ａの周囲の少なくとも基部３１から離れる方向の位置において、押し込み部３２ａ以外でバネ部材４０との干渉を回避可能な開口部３２ｂを有する。【選択図】図１
