Q&A for How to Replace a Lamp Switch

First, take the trim cover off—which is the white cover plate. Then, take the switch out and identify which one has power using a non-contact voltage tester. Finally, put that on the correct terminal point on the new switch, screw it back in and install the trim cover back on.

You can definitely replace a socket switch if it isn't working anymore. Make sure the lamp is unplugged and remove the shade and bulb. The socket shell is the actual assembly where the switch is located and the light bulb screws in. On most lamps, you can squeeze the socket shell and pull upwards to remove it. If it's hard to remove, use a screwdriver to pry it loose. There should be 2 wires attached to the switch. 1 is hot and the other is neutral. The hot wire is usually attached to a brass screw, and the neutral wire is usually attached to a silver screw. Cut through the wires as close to the switch as possible to ensure you have plenty of wire to work with. Then, cut off the ends of the wire and strip away 1⁄2 inch (1.3 cm) of insulation with a pair of wire cutters. Then, use your fingers to wrap the 2 wires tightly around the screw and then push the new socket into the lamp. You can then replace the light bulb, plug in the lamp, and test it out.

It's actually not too difficult. If you're replacing the switch with a new one, you may not need to cut all of the wires. Some switches only require you to connect the hot wire. If this is the case, there will be a channel along one side of the switch for the neutral wire. You may even be able to open the casing of the existing switch and remove the wires without cutting them, but if not, use wire cutters to cut as close to the switch as you can. Try to avoid cutting the neutral wire. If you have to cut it in order to remove the old switch, strip the insulation and connect the cut ends of the neutral wire together. You can also add a plastic connector to protect the wire at the location where you want your new switch to be.

If you're trying to replace your lamp's switch, you definitely want to choose one that is compatible. Luckily, it's relatively easy to figure out which switch you need to get. If your lamp uses a socket switch, it's even easier. Your new switch can be whatever type you prefer, regardless of the existing switch. For instance, if your lamp has a pull chain but you want to install a 3-way turn knob, all you have to do is buy a 3-way turn switch and a light bulb with 2 brightness levels. For a cord switch, look for printing on the lamp cord to determine the size switch you need. Look for printing which says either SPT-1 or SPT-2. The printing is small, so you might have to look carefully, but it'll tell you exactly which switch you need to use.
