3 Way Sockets Vs. 3 Terminal Sockets
Lamp sockets come in a variety of styles, colors, finishes, materials, and flavors. Note: Don't check the flavor of your socket while the lamp is plugged in! There are seriously a lot of things to choose from, but did you know there are also different socket interiors? The socket interiors sit inside the socket shell and come in keyless, push-thru, pull chain, and turn knob. Maybe the most complicated socket interiors are the 3 way and 3 terminal interiors.
