Light switches are very easy to take for granted. They get used countless times over the years, much like an electrical outlet, until one day they start to fail and need a replacement. A few signs of a bad light switch are obvious. For example, if there’s a crackle, pop, or audible snap when you flip it, it’s obvious the switch is defective, and it is time for a replacement. Read on to learn how to diagnose any light switch issues and how to fix them.
Finicky Light Fixtures
We have all had that one switch that just does not work properly. Sometimes it will turn on, and other times it doesn’t. Occasionally it might flicker for a second time before it turns on. Putting in a new light bulb might not even fix the flicker. If this is happening, then the proper connections are not being made within the light switch, which means that it’s time for a new light switch.
The Light Switch Sparks
Occasionally, you might see a tiny spark when you flip on the light switch. This is known as a loaded arc, which happens once the switch connections are pulled away from one another. If a big park makes an audible “snap,” the light switch is faulty. If this happens and you notice smoke and scorch marks, it’s definitely time to grab a new switch.
A Noisy Light Switch
Once working correctly, light switches don’t make any sounds. So, if you begin to hear any buzzing, clicking, or popping coming from the switch, something inside the switch isn’t working the right way. This means it is time to replace the switch.
Light Switch is Warm When Touched
When turning a dimmer switch off, you might notice that it feels a bit warm to touch after being turned on for a while. This is okay. However, it isn’t normal for a standard toggle light switch to be warm. These types of switches should always feel cold. If a switch feels warm, it’s time to call an electrician for a replacement.
