Electrical Safety Receptacle

US Patent:
5261825, Nov 16, 1993
Filed:
Oct 16, 1992
Appl. No.:
7/961665
Inventors:
John S. Chaves - Fairhaven MA
International Classification:
H01R 2900, H01R 1940, H01R 3396
US Classification:

Abstract:
An electrical outlet receptacle adapted to be plugged into a conventional wall socket includes a circuit interrupting switch in the form of a bar or rod axially extending from the receptacle housing and being movable between first and second positions. The receptacle includes a pair of blade contacts engageable with the receptacle of a wall socket which blade contacts have a gap situated therein in such a manner as to orthogonally engage in a slidable fashion the axially movable bar. The latter, in turn, carries a pair of contacts adapted to bridge the gap in the switch blades depending upon the axial position of the bar. Thus, in the first position of the bar, the contacts do not bridge the gaps in the blade contacts whereas in the second position of the bar the contacts do bridge the gaps in the blade contacts thereby permitting an appliance plugged into the safety receptacle to draw electrical power from the wall socket.
