MOVABLE CONTACT MEMBER, AND SWITCH GEAR USING THE SAME

PROBLEM TO BE SOLVED: To provide a rectangular movable contact capable of securing an operation life even when it is miniaturized, and a switch gear using the same.SOLUTION: A movable contact member 1 includes a movable contact part 1a that is curved in an arch shape and can be reversely operated by pressing operation, an always contacting contact part 1c disposed on both sides of the movable contact part 1a for always making contact with a mounting surface 1F, and a connecting part 1d for integrally connecting both ends of the movable contact part 1a and the always contacting contact part 1c. In this movable contact member 1, the movable contact part 1a has a pair of inflection parts 1e with an arc-like apex 1h held between. The switch gear has the movable contact member 1, a first stationary contact making contact with and parting from the movable contact part 1a of the movable contact member 1, a second stationary contact always making contact with the always contacting contact part 1c of the movable contact member 1, and a base on which the first stationary contact and the second stationary contact are provided. 【課題】小型化した場合でも操作寿命を確保できる矩形状の可動接点部材および可動接点部材を用いたスイッチ装置を提供する。【解決手段】可動接点部材１は、アーチ状に湾曲し、押圧操作により反転動作可能な可動接点部１ａと、可動接点部１ａの両側にスリット１ｂを介して配置され、載置面ＩＦに常時接触するための常接接点部１ｃと、可動接点部１ａと常接接点部１ｃとの両端を一体に連結する連結部１ｄと、を備えた可動接点部材１において、可動接点部１ａには、アーチ状の頂部１ｈを挟んで一対の変曲部１ｅを有している構成とした。また、スイッチ装置は、可動接点部材１と、可動接点部材１の可動接点部１ａと接離する第１固定接点と、可動接点部材１の常接接点部１ｃと常接する第２固定接点と、第１固定接点及び第２固定接点とが設けられた基台と、を有する構成とした。【選択図】図２
