Abstract

An electric contactor characterized by improvements including a movable contact carrier structure having a one piece bridge between a pair of movable contacts, the outer ends of which bridge are curved outwardly away from the corresponding stationary contacts, a magnetic coil for actuating the movable contact carrier structure and being embedded in an aluminum die cast base which serves as a better heat sink for the coil, an interlock between the cover and housing of the contactor for preventing operation of the contactor when a cover is removed, and a guide pin for the crossbar of the movable contact carrier structure which guide pin comprises a screw insert for the screw by which the cover is attached to the housing.
