Abstract

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.
