ABSTRACT:
A rotary switch includes a contact bar movable between a switch-open and a switch-closed position and a rotatable circular cam member controlling the movement of said contact bar. Spring means urges the contact bar into operative engagement with the surface of said cam member. The cam member is rotatably contained within a cavity in the switch housing, the cavity having a wall surface guiding the cam member during rotation of the latter. Biasing action of the spring means upon said contact bar urges the cam member against the wall surface of said cavity, with said wall surface serving as the only bearing surface for said cam member during rotation of the latter. A pin and slot coupling is also provided as an integral portion of the cam member and housing to limit rotary movement of said cam member between precise switch-open and switch-closed positions.
