Abstract
A push-pull switch operator includes a housing. A rotary drive is rotationally mounted in the housing and has a circumferential cam track. An actuator is operatively coupled to the rotary drive for converting linear movement of the actuator to rotary movement of the rotary drive. A pusher is received in the housing and has a follower pin riding in the cam track to convert rotary movement of the cylinder to linear movement of the pusher. The pusher actuates an electrical switch. A cap is operatively coupled to the actuator for manually operating the actuator between in, middle and out positions to selectively operate the pusher.
