Signs Your Light Switch May Need To Be Replaced

Posted on: 19 September 2017


A light switch is one of the most overlooked elements of a home. Most people are accustomed to flipping the switch on or off without ever giving the switch a second thought. While this part lasts for decades, at some point in time, it can begin to wear and should be replaced. If you live in an older home, you may be curious as to what the signs are that a light switch needs replacing. Here are a few of those signs:

The Light Switch is Hot

One of the tell-tale signs that your light switch needs to be replaced is a light switch that is hot. Light switches can be warm to the touch. This is completely normal, even with brand new ones. However, you should be able to keep your finger comfortably on the switch. If your switch is so hot that you have to remove it after a couple of seconds, it is getting entirely too hot and needs to be replaced. 

There's a Delay When You Flip the Switch

Another sign that indicates that your light switch needs to be replaced is a delay between the time you flip the switch and the time that it takes your lights to turn on or off. Typically, there should be little to no delay. You flip the switch and the light should immediately come on or off. But if your light switch is nearing the end of its lifespan, there may be a delay or you may find yourself playing with the switch to get the lights to come on or off. 

You Hear Sounds When You Flip the Switch

The last sign that your light switch is nearing the end of its life and should be replaced is strange sounds coming from the switch when you flip it on or off. You may hear different sounds, including popping, cracking, hissing or whining as you flip the switch up or down. This is caused by the wiring behind the switch loosening from the switch and producing live electricity. If you hear these sounds, you want to act fast to replace the light switch or a possible electrical fire could break out. 

If one of your light switches is showing signs that it needs to be replaced, your other switches are sure to be close behind. Contact an electrician today to replace all of the light switches in your home. Check out a website like for more information and assistance.
