Gone with the Wind Lamp Socket, connects with a nightlight socket (see below), for wiring gone with the wind type lamps. Use on table lamps which have a central light and a secondary light in the lamp base. Turn knob switch on brass socket operates both itself and nightlight socket. 3 terminal design enables two sockets to be controlled separately and/or together.
These three terminal sockets provide three options for light: one switch turn - lights only top socket, two switch turns - lights only bottom socket and three switch turns - light both the top and bottom bulbs.
These are quality lamp sockets. Socket shells are solid-brass which are superior to brass-plated and brass-guilt types available elsewhere.
