A safety switch assemblage consisting of a switch housed within a protective casing and having a manually operated control at one end and terminals extending from the other end, the switch carrying a circuit which by-passes the switching circuitry and presents terminals which extend outwardly from the side of the switch, a socket for the switch, the socket having terminals at its base for internal connection with the switch terminals and external connection with a component, the socket having terminals in its side wall in electrical connection with its other terminals so that when the switch is partially withdrawn from the socket primary electrical connection is broken and secondary electrical connection may be optionally established by the union of by-pass terminals with the terminals in the side wall of the socket.
