Why does my wall light switch feel warm?
It's perfectly normal for light switches, particularly dimmers, to feel a little warm when the lights are on. The warmth you feel comes from an electrical component called the triac (triode for alternating current), which varies the amount of electricity that passes through to the light fixture.Is it normal for light switches to get warm?
Dimmer switches get warm, and this is normal. This is part of the function of these switches. As they dissipate the electricity to brighten or dim the lights, they will get warm.

Should a light switch be warm to the touch?
It's perfectly normal for light switches, particularly dimmers, to feel a little warm when the lights are on. The warmth you feel comes from an electrical component called the triac (triode for alternating current), which varies the amount of electricity that passes through to the light fixture.Is it OK for an outlet to be warm?
As more electricity runs to the outlet, you'll notice that you have a hot outlet because of increased power. This issue can typically be solved by unplugging items from the outlet. Then, give the outlet a few hours to cool. If the outlet is still warm, stop using it and call your electrician.What to do if an outlet feels hot?
1. The most important thing to do if an electrical outlet is hot is to find the circuit breaker that controls that outlet, and turn it off. 2. Then unplug everything from the hot outlet.How do I know if my light switch is hot?
Carefully remove the cover plate from the switch, and move the tester near each wire (you won't have to touch the wires, just get near them). If you hear a beep and/or the light turns on, the circuit is hot.Should the switch be hot or common?

To test the switch, you'll need a multimeter or a continuity tester. Remove the switch from the wall, making sure to keep track of which wires are connected to which terminals. With the switch in the "off" position, touch the probes of your tester to the terminals. There should be no continuity.How do you test an electrical wall switch?
Remove the screws on the switch cover plate, and pull off the cover plate to expose the switch wiring. Without touching any wires, test each wire in the electrical box with a non-contact voltage tester. Also, test each of the side terminals on the switch by touching it with the tip of the tester.When should I replace my light switch?
