Abstract
A plug-actuated switchable electrical socket having at least one set of three electrical contacts, two of the three contacts being of a heavier wire gauge than the third contact, the insertion of a plug in the socket effecting a switching action between at least two of the three contacts.
Claims15
A socket adapted to receive a plug and having an electrical switch comprising:
- (a) a first pair of contacts;
- (b) a second pair of contacts;
- (c) a third pair of contacts, the first and second pairs of contacts each having greater current carrying capacity than the third pair of contacts;
- and
- (d) the first and second pairs of contacts being connected together in the absence of a plug in the socket, the first pair of contacts being disconnected from the second pair of contacts and the first pair of contacts being connected to the third pair of contacts when a plug is inserted in the socket.
A socket adapted to receive a plug and having an electrical switch comprising:
- (a) a first pair of contacts;
- (b) a second pair of contacts;
- (c) a third pair of contacts, the first and second pairs of contacts each having greater current carrying capacity than the third pair of contacts;
- and
- (d) the first, second and third pairs of contacts not being connected to each other in the absence of a plug in the socket, but the first, second and third pairs of contacts being connected together when a dummy plug is inserted in the socket.
A socket adapted to receive a plug and having an electrical switch comprising:
- (a) a first pair of contacts adapted to be connected to telephone company wires;
- (b) a second pair of contacts adapted to be connected to subscriber wires;
- (c) a third pair of contacts adapted to be connected to contacts on a plug when the plug is inserted in the socket, the first and second pairs of contacts each having greater current carrying capacity than the third pair of contacts;
- and
- (d) the first and second pairs of contacts being connected together in the absence of a plug in the socket, the first pair of contacts being disconnected from the second pair of contacts and the first pair of contacts being connected to the third pair of contacts when a plug is inserted in the socket.
