You must be asking yourself, “Why is my light switch hot?” and you came to the right place to find answers to that question. Hot light switches shouldn’t be ignored. And there are several reasons your light switches can get hot.
Are You Asking, “Why Is My Light Switch Hot?”
There are many reasons why light switches get hot, but one of the most important questions to ask yourself is whether the light switch is hot or just warm.
You should consider contacting an electrician whether your light switch is warm or hot.
Warm Light Switch
Now that we know the light switch is warm and not hot, we can take a step back and relax for a moment. This isn’t an imminent threat. We now must ask what the type of switch is that is warm. Is this a normal light switch, or is it a dimmer switch?
With light switch, an electrical current passes through the switch to the light fixture. The issue is when the light switch isn’t simply warm but hot. So be sure to routinely check light switches to ensure it stays warm and does not get hot.
Warm Dimmer Switch
Some switches, especially dimmers, usually feel warm to the touch because there is an electrical current passing through the switch to the light fixture, and the warmth being felt is the current passing through the switch.
Dimmer switches restrict the current flow allowed to the light fixture, creating resistance and the heat being felt on light switches. Thus, it’s pretty common for a dimmer switch to feel warm to the touch.
My Light Switch Is Hot
If your light switch is hot to the touch, then there is too much electrical current flowing through the switch. The current flow exceeds the current rating of the switch.
Since the light switch is hot and not warm, there is an electrical problem that needs to be addressed. If the issue isn’t addressed right away, you could be facing an electrical fire in your home.
Overloaded Circuit or Switch
Circuits can be overloaded when the amount of electricity trying to be used exceeds the circuit’s maximum load it can handle.
Light switches can be overloaded just like circuits can be.
Like circuits, switches are rated for specific wattages. When the rating levels are exceeded, degradation of the switch can occur, which leads to electrical issues.
Damaged or Improper Switch
Light switches age just like everything else. They will wear out over time and usage.
It is possible that a small spark on the electrical contacts will emit whenever you turn the light on and off. Eventually, the contacts will not meet properly, and electricity will flow more freely, creating heat.
Improper Wiring
When light switches are not wired properly, it will get hot.
Loose or broken wires that are slightly touching will allow light switch to function, which is why the light is working even though the switch is hot. The electricity will be forced through a smaller path than usual to get to the light fixture, which in turn creates heat.
Fixing Hot Light Switches
The first thing you need to do is turn off the light as soon as possible. Since there is no known diagnosis as to what is causing the heat, you will want to ensure that any electrical current flowing through the switch has been stopped.
Overloaded Switch or Circuit
If the switch or circuit is overloaded, then you will need to change out the switch to handle the appropriate load that is needed.
Damaged or Improper Switch
It’s always a good idea to keep up-to-date on your appliances throughout your home, including all electrical systems like outlets and switches. Old light switches should be replaced to ensure the safety of your home and those in it.
Improper Wiring
