ABSTRACT:
A safety electrical outlet is disclosed which uses a covered outlet box in which the electrical contacts are on the back of the cover, and cannot easily be reached by a person (especially a child) poking into the socket. The contacts in turn form a portion of a circuit with electrically conductive leads and risers from the ordinary business power conduits. The corresponding plug has retractable contact prongs or blades which extend out from the sides of the plug, so that when the plug is inserted into the socket, the sideways-extending blades touch the contacts on the underside of the cover plate and the electrical connection is completed. When it is desired to disengage the plug, the blades are retracted and the plug removed from the socket. Built-in spring-loaded panels cover the plug openings in the cover plate when the plugs are not inserted. There may be a single socket/opening in the cover or there may be two or more ganged openings/sockets. The box, cover and plug may all be colored or decorated as desired.
