ABSTRACT:
A cock and trip switch actuating mechanism for operating a switch inside of a housing, the switch having an energy storage system rotatably mounting on the housing wall and having a cam plate rotatable about a shaft extending perpendicularly of the housing wall, the cam plate having spaced apart notches in the peripheral edge, a switch carriage secured to and moved by the rotatable energy storage plate between switch positions, and a latch mounted on a housing wall juxtaposed to the energy storage mechanism and having a shaft extending through the housing wall, the latch having a reciprocal member which extends to engage a notch in the cam plate to prevent the rotation thereof, the reciprocal member being withdrawn by the rotation of the latching member shaft to permit the plate to rotate in response to energy storage in the springs. An operator utilizes the device by turning a cocking lever to apply mechanical spring force to the energy storage apparatus and then subsequently actuates the trip mechanism which can be done from a remote location.
