What activates a touch lamp?
A touch-sensitive lamp is one that is activated by human touch rather than a flip, push-button, or other mechanical switch. These lamps are popular as desk and nightstand lamps. They act on the principle of body capacitance.

Why is my 3 way lamp not working?
3-Way Bulbs With a 3-way bulb, if it isn't working at all, it's probably dead. You can test it by moving it to a working 3-way socket, but it's very rare that both elements of a 3-way bulb will fail at the same time. But if part of it is coming on and the other part isn't, the problem may be with the socket.
What kind of bulb goes in a touch lamp?
Lighting consultant Terry McGowan said that if a touch lamp has a mechanical switch, it will work with any CFL or LED bulb. However, if the lamp has an electronic switch, you'll need to use a CFL or LED bulb that's specially marked as dimmable.

How does a touch lamp switch work?
Touch lamps work on the principle of capacitance – the amount of charge something can soak up. In circuits, components called capacitors store varying amounts of charge and are used to tune circuits like radio receivers or smooth out fluctuations in voltage.
Do touch lamps turn on by themselves?
Touch lamps work by energizing the lamp casing with a low current AC signal. When you touch it, the capacitance in your body has the effect of taking away some of that signal, which is detected by the circuit inside the lamp and triggers it to turn the lamp on or off.

What do you need to test LED lights?
Basic multimeters measure just amps, volts, and ohms. To test LED lights you will need a multimeter with a diode setting. Check online or at your local hardware store for mid-to-high-range multimeters, which are more likely to have this feature than inexpensive models.
How to test LEDs?
To test your LED, touch the tip of the black probe to the cathode, or shorter end of the LED. Touch the tip of the red probe to the anode, which should be the longer end. Be sure that the two probes do not touch each other during this test, and that the cathode and anode do not touch each other.
How to connect black probe to anode?
Connect the black probe to the cathode and the red probe to the anode. Touch the black probe to the cathode end of the LED, which is usually the shorter prong. Next, touch the red probe to the anode, which should be the longer prong.
How to test battery holder with leads?
If your battery holder has a lead connector, test your LED by inserting the anode and cathode into the small openings that line up with the red and black leads.
How many mV should a LED light display?
When the probes are touching the cathode and anode, an undamaged Led light should display a voltage of approximately 1600 mV. If no reading appears on your screen during the test, start again to make sure the connections were made properly.
What type of battery is used to light LED lights?
Coin cell batteries are the safest option because they do not put out enough of a current to cause damage. Testing with any other type of battery may burn out your LED lights. Buy these batteries at pharmacies, department stores, hardware stores, or online. Use either CR2032 or CR2025 coin cell batteries.
What happens if an LED light doesn't work?
If it does not, separate and reconnect the leads and cathode/anode to try again. If your LED does not light up, it may be burnt out or defective.
