Despite the power flowing through your electrical system, your light switches should not be warm to the touch. If they are, you should call an electrician to fix the problem right away. It typically indicates a serious wiring or wattage issue that may present safety concerns. The guide below looks closer at potential causes.

Why Are My Light Switches Hot?

1. Overloaded Switch

Light switches can only handle a certain amount of power—typically 15 amps. If one is hooked up to a circuit that delivers power above its limits—say, 20 amps—this can translate into heat. It may also cause the light to flicker, blink, or dim. To avoid this problem, an electrician may need to replace the switch.

2. Failing Switch

Like many electrical fixtures, light switches can wear down over time. When this happens, the wiring connections can separate, which creates a spark whenever the light goes on and off. This leads to noticeable heat, creating a fire hazard. Some lights may even stop working altogether.

Switch out old light switches to avoid this problem. Typically, these fixtures should be replaced after about 15 years. 

3. Improper Wiring

Even if a light switch isn’t old, the wires can emit heat if they’re not connected properly. This sometimes occurs with DIY installation. Even if you are handy, wiring a house often requires years of training and experience. Therefore, call right away if you notice heat or sparks when you turn on your lights. You might also feel vibrations in the wall or smell a burning odor.

Additionally, have a professional install any new lights or switches you want to add throughout your home to avoid this problem in the future.
