A light switch that is slightly warm to the touch indicates a possible electrical fault. Prompt attention from licensed electricians can address the issue and ensure your light switches remain at a normal temperature and maintain optimal function. Mister Sparky® offers professional electrical repair services to identify electrical issues and mitigate fire risks.
Top Reasons Your Light Switch Is Hot
There are several reasons why your light switch gets hotter than normal. The type of repair service you need may vary depending on the cause, but an electrical inspection is always necessary. Below are the most common reasons why your light switch may be hot:
Overloaded Circuit
Having too many lights or devices connected to the same circuit can generate excess current and cause light switches to get hot. To avoid overloading your circuit, use switches with a higher power capacity if you frequently use multiple devices simultaneously.
Loose or Damaged Wiring
Faulty wiring is another possible cause for a hot light switch. This happens when the wiring is not properly installed or has deteriorated over time. If left unattended, loose or damaged wiring can cause your light switch to spark and start a fire.
Dimmer Switches
Dimmer switches tend to run warmer than standard switches because of the way they regulate electrical flow. If you're using dimmer switches and they feel warm, it's likely not a cause for concern. However, they shouldn't feel uncomfortably hot. Otherwise, an inspection might be necessary.
High Humidity
External environmental factors may affect the performance of your light switch and cause it to become hot. A high humidity level is a common cause of light switch failure, as it accelerates the oxidation of internal parts and increases the risk of overheating.
What to Do When Your Light Switch Gets Hot
If you notice your light switch feels warm to the touch and are unsure how to fix the problem, here's what you need to do:
- Turn off the power to the faulty switch at the circuit breaker.
- Stop using the switch until a thorough electrical inspection has been conducted.
- Contact a licensed electrician, such as Mister Sparky®, to diagnose the problem.
