Quick answer
To fix a table lamp switch that is broken, first rule out the bulb and the outlet, then replace the socket with a lamp socket and switch replacement kit. It costs a few dollars and takes about 15 minutes with a screwdriver. Always unplug the lamp before you open it. If the cord is cracked or the plug is hot, stop and replace the cord or the lamp.
Free fix vs. permanent fix
Check the bulb, the outlet and the contact tab
- Try a new bulb and a different outlet
- Unplug, then look for a flat brass tab in the socket
- Lift the tab a little with a small screwdriver
- Check the cord and plug for damage
How long it lasts: Solves a lamp where the real problem was a dead bulb, a bad outlet or a flattened tab. A switch that is worn out will fail again.
A lamp socket and switch replacement kit
Switches wear out from thousands of clicks. Inside, the metal contacts burn and the spring tires, and the part cannot be fixed. A new socket costs far less than a new lamp and goes into the same base and shell, so the lamp looks the same when you are done.
What to get: Lamp socket and switch replacement kit
How long it lasts: Years. A new socket has new contacts and a fresh switch.

Why it happens
A worn switch
A turn knob or pull chain has metal contacts and a spring. After years of use they burn, and the lamp lights only if you hold the knob a certain way, or not at all.
A loose wire at the terminal screws
Heat and handling can loosen the two screws that hold the cord wires. The lamp flickers or cuts out when you move it.
A flattened contact tab
At the bottom of the socket is a small brass tab that touches the base of the bulb. If it gets pressed flat, the bulb makes no contact.
A dead bulb or a bad outlet
A new bulb and another outlet rule out the cheapest causes. Do that before you open anything.
A damaged cord or plug
A cracked jacket, a bent plug or a loose connection at the plug can look like a switch problem. These are safety problems, not just repairs.

Do these in order, starting with the simplest.
-
Test the basics
Tool used: Replacement bulbPut a bulb you know works into the lamp, and plug the lamp into an outlet you know works. If the outlet is switched or on a smart plug, check that too.
-
Inspect the cord and plug
Run your hand along the cord. A cracked jacket, bare wire, a hot or discolored plug or a burning smell means stop. Do not use the lamp until the cord is replaced.
-
Unplug, then check the tab
Tool used: Small screwdriverWith the lamp unplugged and the bulb out, look into the socket. If the brass tab at the bottom is flat, lift it about 1/8 inch with a small flat screwdriver. Refit the bulb and test.
-
Photograph the wiring
Tool used: Phone cameraUnplug the lamp and remove the shade and bulb. Squeeze the metal shell where it says Press, then pull the shell off the cap. Slide the socket out and photograph how the two wires attach.
-
Swap in the new socket
Tool used: Lamp socket and switch replacement kitLoosen the two terminal screws and free the wires. Attach the ribbed or marked wire to the silver screw and the smooth wire to the brass screw. Tighten, slide the new socket into its shell and press it into the cap until it clicks. Test with a bulb.

When free fixes aren't enough
If a known-good bulb in a known-good outlet still will not light and the tab is fine, the switch is worn out and the socket needs replacing. Stop and call an electrician, or replace the lamp, if the cord is cracked, the plug is hot or discolored, the lamp trips a breaker or you smell burning. A cord with damaged insulation is a fire and shock risk, and a full rewire kit with a new cord is the safer fix.

How we picked: How we picked: this page is based on lamp repair guides, safety advice on lamp wiring, the instructions that come with replacement sockets, and the problems and fixes people report in reviews. We do not test products by hand.
Match the switch type before you buy
- Turn knob: the most common on table lamps. Look for a socket with the same knob.
- Push-through: a button on the side of the socket.
- Pull chain: a chain hangs from the socket.
- 3-way: needs a 3-way socket and a 3-way bulb. A regular socket will not give you the three brightness levels.
What to skip
Tape on a failing switch, and unlisted sockets
Electrical tape around a broken switch or a cracked cord only hides a fire risk. A switch that has failed inside should be replaced, not wrapped. Also skip sockets or cords with no safety mark on the package.
