Cracked Black Plastic Sockets Are An Easy Fix

Many lamps today are made with inexpensive components. Specifically, I mean the black plastic sockets used in most household table lamps. These sockets are brittle and easily chipped and cracked. If you are like me and often shop in the closeout section or the "imperfect" type of store, you will easily find these sockets cracked, chipped, and often missing on the lamps for sale. The good news is they are really easy to fix.

As this video demonstrates, there are 3 parts of the plastic socket: cap (bottom), shell (top), and the socket interior. The shell screws on to the cap and can be replaced in a few minutes.

Don't let those cracked, chipped or bent lamp parts keep you from getting the lamp you like.

3 Way Keyless Socket Interior

A keyless socket interior or keyless socket is not a typical lamp socket. It doesn't have a switch function so the circuit control needs to be performed by another mechanism. The keyless socket is the true "lamp holder" with no other purpose. Keyless sockets are ideal for pendant lamps (use a switch on the wall) or chandeliers (one switch controls all the lights) and some cluster lamps.

The more complicated keyless socket is a 3-way socket. Designed for 3-way bulbs, the 3-way socket has the extra contact point on the base of the socket. 3-way bulbs have a low, medium, and high setting from having 2 sets of filaments.

For the 3-way socket to work with the 3-way bulb, you will need a 3-way switch and wire it in the correct order. Our 40402 switches are 2 circuit and will work with a 3-way interior.

Here is a wiring diagram to make it work:

The switch has 4 positions and the socket has 3 screw terminals. As the diagram shows, the smooth lamp cord wire connects to the black wire of the switch. The ribbed lamp cord connects to the nickel screw terminal on the socket. The red wire is the first circuit to turn on so it connects to the brass plated screw terminal and the blue wire connects to the black screw terminal. In the 4th position of the switch, both red and blue wires are on the closed circuit and the 3-way bulb has both filaments lit.
