Zusammenfassung:PROBLEM TO BE SOLVED: To provide a thin and inexpensive push button switch that is not easily broken.SOLUTION: A push button switch comprises: a front panel including a button; an actuator that moves by pushing the button of the front panel; a substrate including a control circuit that performs energization control by operating a current-carrying switch arranged at the rear side of the button, in response to the operation of the button; a resin member that is arranged at the rear side of the actuator and the substrate; and a leaf spring that is arranged at the rear side of the resin member. The actuator has a drive shaft that comes into contact with the leaf spring after penetrating through the resin member, and with the button being pushed, the drive shaft of the actuator deflects the leaf spring. Thereby, an end part at the side opposite to the contact portion of the drive shaft of the leaf spring drives the current-carrying switch arranged at the rear side of the substrate. 【課題】 薄型でまた壊れにくく、コストも安価な押しボタンスイッチを提供する。【解決手段】 ボタンを有するフロントパネルと、フロントパネルのボタンが押されたことにより動くアクチュエータと、ボタンの操作に応じて、この裏面側に配置された通電スイッチが操作されることで、通電制御を行う制御回路を有する基板と、アクチュエータ及び基板の裏面側に配置された樹脂部材と、樹脂部材の裏面に配置された板ばねとを有し、アクチュエータには、樹脂部材を貫通して板ばねに当接する駆動軸を有しており、ボタンが押されることにより、アクチュエータの駆動軸が板ばねを撓ませることで、板ばねの駆動軸の当接部分とは反対側の端部が、基板の裏面側に設けられた通電スイッチを駆動させることとした。【選択図】図1
