ABSTRACT:
A pivoted operator d(4) for an electric switch has an inwardly extending actuating leg (4d) having direct connection with a contactor (12) to provide over-center pivoting and sliding motion for the contactor. The inner end of the actuating leg has a first slot (4f) wherein the actuator leg straddles the contactor and has grooved (4h) interior surfaces which receive outward lateral projections (12a) on the contactor for affecting a driving connection therebetween. The depending leg has a cylindrical recess (4e) which receives a helical compression spring (14) to bear between the operator and the contactor. Transversely aligned connection points (12a, 4h) actuator and contactor and the edges of the slot (4f) in the actuator cooperating with the lateral edges of the contactor (12) guide the latter throughout its longitudinal movement to prevent angular displacement in a horizontal plane of the contactor within the switch.
