How to Know If a Light Switch is Bad

Since light switches are used every day, it is easy to take them for granted. However, a dysfunctional switch often becomes noticed right away. Still, while the problem may be difficult to ignore, it can be challenging to know the cause of the switch’s failure. Many people deal with their stubborn switch for days, weeks or even months, simply because they are not sure what step to take next. At Mr. Electric of Fort Worth, we proudly provide high quality residential and commercial electrical services for clients in Fort Worth, Texas and surrounding DFW area communities. We enjoy helping our customers improve the safety and effectiveness of their electrical system, and we want to do the same for you. While a broken light switch may seem somewhat insignificant, neglecting to fix the issue could put you at risk of fires, property damage or personal injury. If you are worried about the condition of one or more of your light switches, here are some tips on how to solve the issue. 

Unreliable Fixture 

At first glance, it may seem that the problem lies with your switch, when your light fixture is the culprit. Try swapping out the fixture with a new model, and test to see if you get the same result. If you are still experiencing flickering bulbs or inconsistency, then you will likely need to replace the switch. 


Do you sometimes see a small spark when you flip the switch? A load arc is a relatively common event that can occur when a connection is made within the light switch. However, if you see a large spark that is accompanied by a snapping sound, then your light switch needs a replacement. 

Strange Noises

Have you noticed an unusual buzzing, popping or clicking sound in the area around your switch? This can indicate a wiring issue and should be resolved as soon as possible to avoid further development. A licensed electrician in Fort Worth will be able to conduct an inspection and pinpoint the cause of the noises. 

Feels Hot 

While it may be normal for a dimmer switch to feel a little warm to the touch after use, conventional light switches should always remain at room temperature. If you feel heat coming from your light switch, or see smoke, then call a local electrician right away.
