A safety switch, operable by a removable coded actuator, is designed for mounting on a support surface in four different orientations. The switch has a substantially square cross-section and grooves or holes for receiving mounting fasteners extend across each side of the switch housing, the grooves being located in a common plane intermediate the ends of the housing.

Safety switch

An electrical switch for use as a safety switch for doors of lifts or elevators, the contact push rod of which is actuated by a switching roller when the roller is turned by means of an inserted actuating member. The switching roller comprises two axially spreadable switching roller portions that can be spread against the force of a spring by a pin specially provided for that purpose on the actuating member; if there is no pin on the actuating member, the roller strikes a stop before the switch is closed.

Electrical switch

An electrical interlock comprising a switch operated by a rotatable cam member coupled to the movable switch contacts by a longitudinally movable slider. Rotation of the cam member, which is contained within the same housing as the switch contacts, is caused by engagement, in slots in the periphery of the cam member, of an actuator mounted for movement relative to the switch housing.
