ABSTRACT:
A socket mountable in a light fixture such as a table or floor lamp or a wall fixture. An electric light bulb is mounted in the socket, and is switched off and on by means of a central lower axial switch, the turn knob of the switch depending downwards from the socket. The improved bottom turn socket features a husk and cooperating lower cover housing about the switch. The housing includes at least one interior boss. The electric line cord is placed in a slot in the cover housing, and the boss, which is adjacent the slot, pinches the line cord against an end of the husk when the cover housing is emplaced, to provide strain relief. Preferably, two slots are provided in the cover housing, each having an associated adjacent interior boss to provide strain relief, so that a second line cord electrically connected in parallel within the bottom turn socket may extend from the husk of the socket to another light fixture.
