PROBLEM TO BE SOLVED: To provide a rotary switch device capable of maintaining preferred contact performance for a long time by preventing variation of a contact pressure between contact points.SOLUTION: A rotary switch device comprises: a terminal base 3 in which a central part contact point 1 and a fixing contact point are fixed; a rotation operation member 4 that is rotatable to the terminal base; a plate-like movable contact pint member 7 that includes a contact projection part 5 pressure-welded to the central part contact point in one end, and a contact surface 6 with the fixing contact point in the other end, and that allows between of the central part contact point and the fixing contact point to be short-circuited at a conductive rotation position; and compression coil springs 10 and 10 in which one end is supported by a spring housing hole 8 and the other end energizes the contact projection part and the contact surface to the terminal base side. In a bottom pat of the spring housing hole, a bowl part 11 of which a bottom surface is formed in a circular form having a diameter almost similar to a coil outer diameter in a supported end of a compression coil spring or a polygonal shape having an inscription circle with the circular form, and which is gradually expanded toward an opening edge.SELECTED DRAWING: Figure 5

    【課題】接点間の接触圧のばらつきを防止することにより、長期にわたって良好な接触性能を維持できるロータリースイッチ装置を提供する。【解決手段】中央部接点1、および固定接点が固定されたターミナルベース3と、ターミナルベースに対して回転操作可能な回転操作部材4と、一端に中央部接点に圧接するコンタクト突部5を、他端に固定接点とのコンタクト面6を備えて、導通回転位置において中央部接点と固定接点間を短絡させる板状の可動接点部材7と、一端がばね収容孔8に支承され、他端がコンタクト突部、および、およびコンタクト面をターミナルベース側に付勢する圧縮コイルばね10、10とを有し、ばね収容孔の底部には、底面が圧縮コイルばねの被支承端におけるコイル外径とほぼ等径の円形、あるいは円形を内接円とする多角形形状をなし、開放端に行くに従って漸次拡開するすり鉢部11が形成される。【選択図】図5
