Abstract
A rotary switch device includes a fixed contact point part and a movable contact point part. The movable contact point part is rotated on the fixed contact point part so as to connect and disconnect the fixed contact point part and the movable contact point part. The fixed contact point part and the movable contact point part have contact surfaces which are band shapes and to which corrosion-resistant conductive processing is applied. A transient contact region, in which a contact point is moved from one end portion to the other end portion in a predetermined connection-operation angle from a contact start point with respect to the other of the fixed contact point part and the movable contact point part, is provided on each of the contact surfaces.
