A light switch can stop working over time because the contacts—the parts that carry electricity—can eventually wear out. This is the most common cause for a light switch to go bad, but there could be other reasons why you’re having problems with your lights. The best way to deal with a bad switch is to find a licensed electrician near you to diagnose and fix the problem. Here, we walk you through some key things to know about a light switch going bad.
Rule Out These Common Problems First

Before you conclude that a faulty light switch is to blame for a problem turning on the lights, start by ruling out some other possible causes. The most common cause of a light not coming on is a burned out lightbulb. There could also be a tripped breaker causing the light switch not to work. You can reset your circuit breaker at the box to see if that’s the problem.
The Light Switch Is On, but There’s No Power
Assuming the breaker isn’t tripped, if there’s no power to a light fixture when the light switch is in the on position, it most often means there’s a gap in the electrical contacts of the switch. There could also be something wrong with the light fixture itself or a problem with the wiring going to the switch. A licensed electrician can help determine the root of the problem.
The Light Switch Is Hot or Warm to the Touch
If your light switch is overheating, you should turn power to it off at the breaker immediately. This can be a sign that there is a problem with your switch and that there is electricity taking an unplanned path somewhere. This can be dangerous because of the risk of shock, so turning the power off to the switch until you can get a licensed electrician to troubleshoot your problem is the safest choice.
The Light Switch Makes Noise or Sparks
Sparking is an obvious sign that there’s electricity arcing inside the switch. A popping sound is also a warning sign of arcing. If these are occurring at the switch, you should turn off the power and hire an electrician to replace the switch. Since arcing can cause a fire, it’s important to address it immediately.
Lights Flicker or Switch Takes a Moment to Respond
If the lights flicker after you flip the light switch on, there could be a problem with the light fixture or with the switch itself. Flickering is often the first sign that the contacts in your light switch are beginning to wear down. Although this problem is often not dangerous, it’s a good idea to have an electrician take a look to make sure you’re not dealing with something more serious and potentially unsafe.

I conferred with 2 other contractors before Armstrong Electric. Nick and his crew showed me that the project was not as convoluted as the other contractors made it appear to be. They completed the entire project on time. They were professional, friendly and cleaned up after at completion. I...

Victor was wonderful. He was on time, professional, and explained everything he was doing. He was thorough and figured out that the problem was electrical instead of with my HVAC system. Very knowledgeable. I will be using this company in the future for any HVAC needs. Thanks!

Initially, the repairman could not find the problem. Apparently, there was some electrical shortage, but he could not find the definite problem. He left, but called back later to say he had a new idea. He returned and replaced the light switches on the doors. The refrigerator seemed to return...

The initial quoted price from a walk-through seemed high, but we discussed that the quote represented worst case scenario (re-wiring to two floors) and we were excited about the opportunity to have the work done in a timely manner with closing for fire safety reasons, etc. When the job was...

When I challenged the markup on the generator, Bruder Electric withdrew its bid. They only want naïve customers.

We had no power to any of the electrical outlets in the MBR. We'd had an intermittent problem for a few years and they finally went out all together. We live on the 3rd floor of a 100 year old building and I know from past experience the wiring has been added to in hodgepodge ways over the...
