Abstract
A rotary switch device includes a terminal base to which a center portion contact and a fixed contact member are fixed, a movable contact member, and a support portion. The movable contact member includes a contact protrusion part which is pressed in contact with the center portion contact at one end of the movable contact member and a first contact surface which is in contact with the fixed contact member at another end of the movable contact member, and which is operated to rotate around the center portion contact so as to short-circuit between the center portion contact and the fixed contact member at a conductive rotation position.
