Touch Sensitive Lamp Switch

The good ole touch sensitive lamp is a really unique idea. The sensor turns the whole lamp into a switch. No need to clumsily fumble around with the cord or the side of the socket to look for that menacing switch. Que the infomercial clumsy reel.







I digress. The idea is really more scientific. According to Wikipedia "They act on the principle of body capacitance." And body capacitance?

Body capacitance is the physical property of the human body that has it act as a capacitor. Like any other electrically-conductive object, a human body can store electric charge if insulated.

Finally, my superpower is revealed! I can turn on a lamp with the touch of my finger. Now that is cool.

The uncool part is these switches have a tendency to stop working. Instead of sending the lamp to a landfill, simply replace the touch sensitive switch.



Now you are two superheros: Thor and Captain Planet.

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.

40402N - 3-Way 2 Circuit Nickel Rotary Switch
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.

6 Arm Chandelier With Cluster Gets Rewired

A customer brought in this chandelier the other day and asked to have it rewired. After looking at the sockets and wiring, we agreed this chandelier needed new wires, sockets, and candle covers.


As usual for any repair, we want to look at the whole project and make a list of required items. Too many trips to the hardware store can discourage from future projects. The lamp parts we need for this project are:

6 - Adjustable Keyless Fixture Sockets
Adjustable Keyless Candelabra


6 - White Paper Candle Covers
Flat White Smooth Plain Paper Board Candle Cover


2 - Wire Nuts or Wire Connectors
Wire Nuts


40 - 45 foot of Clear Silver SPT-1 Lamp Wire

Here you can choose the value option of a spool:

Or you can get 4 of the 12 foot Cord Sets with Clear Silver SPT-1 and Cut them to size:

With all the lamp parts ready, we will begin the repair. First, we will hang the lamp for access and remove the excess chain and other parts that are just in the way.





Next, we unscrew the bottom cluster cap from the cluster body.



Now we can move this project to the table top and begin to remove the body pieces off the column of the chandelier. The top loop unscrews from the threaded rod. Since we are rewiring this fixture, we cut the cord at the top of the column so when the parts are removed, they do not have to go through excess wire.






The rest of the column pieces slip off the threaded rod. Remember to take a picture or keep the parts in the right order for reassembly. The final piece sets just on top of the cluster.








Next, we will focus on rewiring 1 arm at a time. With 6 arms, each one is wired the same way. We remove any existing wire nuts, connectors, or in this case: tape. The old candle covers slip off the old fixture sockets. Cut the wires or unscrew the screw terminals on the socket and disconnect the wire. Unscrew the socket from the threaded rod in the dish or bobesche of the chandelier. Repeat for the other chandelier arms.








Pull the old wires out of the chandelier arms. If the arms are narrow or have complex bends, you can attach the new cord to the old cord. Then when you pull the old wire out, the new wire pulls in behind it. We have discussed this technique in other post of the blog. For this chandelier, the arms are straight and short. Each arm is wired with about 5 inches slack on the socket end and in the cluster.







The new fixture socket screws on the thread of the arm. The wire is striped about 1/2 inch and connected to the screw terminal. The wire look similar, but there is a thin rib on one wire and the other wire is smooth. Typically in house wires there is a hot wire and a neutral wire. For lighting we want to wire the hot to hot so most often the smooth wire is designated for the hot side or the black house wire.

For chandelier sockets, connect the smooth wire to the brass screw terminal. Connect the ribbed wire to the nickle screw terminal. Make sure each socket is wired the same. Replace the wire from the column or body of the chandelier making sure you leave plenty of length for the chain or any drop length. In the cluster connect the smooth wires together with the smooth wire to the canopy and the ribbed wires are all connected together.





The column pieces are slipped back over the center rod of the chandelier. Refer to the photo you took earlier before the lamp was disassembled. The top loop screws back on the threaded rod.







Reconnect the chain to the top loop of the column.







Hang the chandelier up and reconnect the bottom part of the cluster.





Slip paper insulators and the candle covers over the fixture sockets.







This chandelier is ready for some bulbs and power.


With new wires, sockets, and insulators, this chandelier is ready for use.
