ABSTRACT:
A molded electrical lamp socket includes threaded, insulating portions on the inner wall of the socket to engage the lamp. The side electrode providing electrical contact for the lamp is desirably set deeply within the socket, to reduce the danger of accidental finger contact with an electrically conducting lamp. Where the side electrode is of the edge-on type, the insulating threads center the lamp in the socket and reduce the incidence of shaving and jamming of the lamp.
