Turn-Knob Light Sockets


Turn-knob sockets are one of the most popular and widely used styles of lamp sockets available. 1000Bulbs.com features three product categories of turn-knob sockets - on/off sockets, 3-way sockets and 3 terminal sockets. On/off Sockets are the simple light bulb sockets operated by the familiar black turn-knob. 3-way sockets are controlled with that same type of knob but use two terminals and two circuits to provide three different lighting levels. They are different from 3-terminal sockets, which are made to control two different bulbs, one in the base and one on top. The availability of these different product categories makes finding your perfect turn-knob lamp socket quick and convenient.
