4 Common Reasons Why Your Light Switch Is Hot

When you reach for your light switch to turn it off, only to find that it’s hot to the touch, you have a problem. A hot light switch is not normal and could indicate potential dangers lurking in your walls.

If you don’t get help right away, you could end up facing a serious electrical fire in your home. At John Nugent & Sons, we prioritize your safety. Here are common reasons why your light switch is hot and when to call for professional service.

1. The Switch Is Overloaded

Just like wall outlets, light switches have a limit on how much power they can handle, and different switches are rated for different levels of power. If you’re asking too much from the wall switch, it can get hot.

Most wall switches are rated for 15 amps. However, many circuits are pulling 20 amps. If you’re overloading the switch, you have a serious fire risk and need to replace it with one that can handle the appropriate load.

2. The Switch Is Failing

Over time, light switches will wear out. When this happens, a small spark on the electrical contacts will be emitted whenever you turn the light on and off. Soon the contacts won’t meet properly, and electricity will flow more freely, creating heat. Again, this is a fire risk. Replacing old light switches is always a good idea.

3. Faulty Wiring

If the light switch was improperly wired, it will get hot. Loose or broken wires that are still slightly touching will allow the light switch to function. However, the electricity will be forced through a smaller path, which will create heat. Again, this is a fire risk.

4. Function of Dimmer Switches

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. If you think they’re getting too warm, you need to call for service and inspection. It’s possible to have the first three problems with a dimmer switch.
