Abstract:
A rotary switch device in which fixed contacts are fixed on one of opposite face sides of a base member made of a synthetic resin, a contact plate in a ring shape is floatingly held by a rotor disposed opposed to the one face side of said base member, movable contacts capable of switching the connection and disconnection to and from said fixed contacts in accordance with the rotation of said rotor are integrally formed at a plurality of places spaced from each other at circumferential intervals on said contacts plate, and sliding faces capable of being brought into slide contact with said moveable contacts are formed on the one of opposite faces of said base member closer to said rotor along a plane orthogonal to a rotation axis of said rotor, wherein said sliding faces are formed on said base member so as to avoid loci which are drawn by portions of said movable contacts to be brought into slide contact with said fixed contacts in accordance with the rotation of said rotor, wherein a plurality of bus bars integrally provided with said fixed contacts are embedded in said base member and a plurality of opening portions for exposing said respective bus bars to an outside are provided in another face of said base member.
