Abstract: A safety switch assembly comprises a safety switch for securement to an enclosure having an openable closure, and an actuator for operating the safety switch for securement to the closure. The safety switch comprises a housing, containing electrical contacts, and a cam arrangement for operating the electrical contacts and formed with peripheral inwardly directed radial pockets. An axially-movable rod connects the electrical contacts and the cam arrangement. The housing has openings adjacent the cam arrangement for insertion of the actuator. The cam arrangement comprises a shaft bridging lateral walls of the housing, and an actuating cam rotatably supported on the shaft and connected to the rod by a cam follower pin connected to the rod and engaged in cam grooves in the actuating cam.
