PROBLEM TO BE SOLVED: To provide a rotary switch device capable of being used in both high current and low current.SOLUTION: Disclosed is a rotary switch device which connects or disconnects a fixed contact point (1) and a movable contact point (2) by rotating the movable contact point (2) on the fixed contact point (1). Both of the contact points have a contact surface which is made to be electro-conductive in a band shape for rust prevention, and both contact surfaces are provided with an excessive contact region (3) on which a point of contact with regard to the other contact point within a predetermined connection-operation angle moves from one edge towards another edge after contact begins.
【課題】高電流、低電流の双方で使用可能なロータリースイッチ装置の提供を目的とする。【解決手段】固定接点1上で可動接点2を回転させて固定接点1と可動接点2とを断接するロータリースイッチ装置であって、前記両接点は帯状で防蝕用導電加工が施された接触面を有し、双方の接触面には、接触開始から所定の接続操作角の間に他方に対する接触点が一端部から他端部に向けて移動する過渡接触領域3が設けられる。【選択図】 図4
