How to Tell if a Light Switch is Bad

At Mr. Electric of Dallas, we understand the mechanics of light switches and ensure long-term solutions to mitigate further damage. While a malfunctioning light switch doesn’t seem like a serious problem, delaying repairs can lead to costly electrical switch replacement projects or safety hazards. Here are signs you need to call an electrician to replace your light switches.

Choosy Light Fixture

We have all experienced one light switch that doesn’t work as expected. Sometimes it turns on, other times you need several tries before it functions. If you notice a flickering fixture, try changing the bulb to see if it will rectify the problem. In case the bulb isn’t the issue, chances are there is a faulty connection in the light switch. Avoid using the fixture until the switch is fixed or replaced based on the severity of the damage.

The Switch Sparks

When you flip a light switch and it sparks, you need to schedule an inspection with an electrical service as soon as possible. A sparking light switch, also called a load arc, happens when the connection within the outlet is away. Small sparks can signal the switch is salvageable, but large sparks with an audible "snap" show severe damage, and replacement is imminent. There are situations when you see scorch marks or smoke telling you it’s time to get a new light switch.
