とを特徴とする。In order to achieve the above object, the present invention relates to a rotor in which a fixed contact is fixed to one surface of a base member made of synthetic resin, and which is disposed opposite to one surface of the base member. A ring-shaped contact plate is floatingly held, and movable contacts capable of switching connection / disconnection with the fixed contact in accordance with the rotation of the rotor are provided at a plurality of locations spaced apart in the circumferential direction of the contact plate. In a rotary switch device, the sliding member is formed integrally, and a sliding surface slidably contacting the movable contact is formed on a surface of the base member on a rotor side along a plane perpendicular to a rotation axis of the rotor. The moving surface is formed on the base member so that a range of the movable contact to be brought into sliding contact with the fixed contact avoids a locus drawn according to the rotation of the rotor.
