Title: Safety plug socket

Abstract: A safety plug socket has two independently actuated circuit breakers. The two circuit breakers are in the form of a common C-shaped leaf spring and two conducting actuating pins which are movable to close the circuit breakers when a plug on a line cord from a consumer appliance is inserted into the socket of the circuit outlet to move the actuating pins of the two circuit breakers into contact with the conductive leaf spring. In one form of the invention, the biasing springs of the circuit breakers are current carrying and form a part of the supply circuit. In another form of the invention, each circuit element comprises leaf spring contact arms which are bridged by a conductive bridging member carried by respectively actuating pins of the circuit breakers. Power can only be obtained from the outlet socket when both circuit breakers are closed and when the plug from the consumer appliance has been moved into the outlet socket, which action closes off access to the tubular contacts to the circuit breakers.
