What Is Wrong with My Light Switch?

The good news is that a faulty light switch doesn’t automatically mean there’s a big electrical problem. Sometimes, the issue is simple and easy to fix. In this brief article brought to you by Mr. Electric, we explore some possibilities.

Light bulb is burned out

Sometimes the reason your light switch isn’t working is simply because the light bulb has burned out. Before you start worrying about wiring or electrical panels, check to see if a new bulb solves the problem.

Loose or faulty wiring

Over time, the wires connected to the light switch can become loose or wear out. If the wires inside the switch box are loose, it may cause the switch to fail intermittently or stop working altogether. You might be dealing with loose or faulty wiring if:

• The lights flicker or turn off randomly.
• The switch feels loose or wobbly when you toggle it.
• You hear a faint buzzing or crackling sound when you flip the switch.

Re-tightening the screws and reattaching the wires is easier said that done, especially when you consider the electrical risks. However, this is typically the solution for loose wiring.

Worn out switch mechanism

A light switch gets flipped hundreds, if not thousands, of times over its lifespan. Eventually, the internal mechanism may break down. If the switch is old, it may simply be time for a replacement. Here are some signs of a worn out switch:

• The switch doesn’t click as solidly as it used to.
• The lights do not respond when you flip the switch.
• The switch feels stiff or stuck.

You can pick up a switch at your local hardware shop, turn off the power, and swap out the old switch for a new one, but this is going to also involve working with the wiring. If you’re not familiar with electrical work, then it’s worth hiring a professional.
