ABSTRACT:
The plug-switch includes a pair of terminal blades projecting outwardly of a housing for insertion in an electrical socket, and first and second pairs of contacts. A carrier member, which is movable within the housing between first and second positions, is normally biased to its first position by spring means and is movable from its first position to its second position by engagement with a member associated with an electrical socket. A pair of contact members, which are carried by the carrier member, serve to bridge either the terminal blades and one pair of the contacts or the terminal blades and the other pair of the contacts.
