ABSTRACT:
An electrical connector is formed from two pairs of contacts. One pair of contacts is rotatable with respect to the other pair of contacts. Both pairs are in conductive and frictional engagement throughout a 90 degree rotational distance. One pair of contacts have an arcuate conductive contact surface, each contact being symmetrically arranged with respect to the axis of rotation, in opposed relation to one another and separated at each end by a non-conductive space. One pair of contacts are attached to a pair of male electrical prongs. The other pair of contacts are attached to an electrical appliance. The one pair of contacts and the attached pair of male electrical prongs are themselves attached to a nonconductive disk. The nonconductive disk is disposed in a circular groove in a disk holder. The nonconductive disk and the pair of contacts and electrical prongs attached thereto are rotatable within the circular groove. Stops are employed to limit the rotational distance to 90 degree. The electrical connector allows an electrical appliance, such as a night light, attached to the connector to be oriented in a desired direction regardless of whether an outlet is vertically or horizontally disposed.
