Signs That Your Wall Switch Needs Professional Repairs

Like any electrical appliance, tool, or feature, wall switches are prone to wear over time, which is why any homeowner will need electrical repairs at least once in their life. Now, there are a few signs that can let you know if you need to call a professional to fix your wall switch.

If you notice any of these things happening, it's best to address the problem immediately to avoid any accidents. Incidents involving electricity can often cause electrocution or fire.

Here are some of the telltale signs of a defective wall switch:

The Switch is Physically Damaged

One of the most common signs is if the wall switch becomes physically damaged from wear and tear. If you notice the switch is cracked or dented, it may be time to replace it.

Depending on the severity of the cracking or dents, you may want to contact a professional to avoid any potential electric shock that could cause you and your family harm.

It Doesn't Turn On Lights or Appliances

Lights and appliances that don’t turn on are another common sign that you may need to repair your wall switch. If it's connected to lighting and you're sure that the bulb isn't the problem, it's a good idea to get your switch looked at.

If you press the switch and nothing happens every time, it usually means there's no connection between the switch and the circuit.

It Works Intermittently

A switch that works intermittently means that sometimes it turns your lights or appliances on, and sometimes it doesn't. There's no logical pattern, and it can happen at any time of the day.

Not only is this annoying, but it's also a sign of a wiring problem.

The switch should work all the time, even if you press it lightly or in a certain way. It's best to hire electrical services to determine if it's a wiring issue or a problem with the switch itself.

It's Warm to the Touch

If you press the switch and notice that it's warm to the touch after a short while, that's a sign it's drawing too much power and will soon burn out. It could cause a short circuit on the switch and lead to bigger problems if you do not address it immediately.

It Makes a Buzzing Sound

A buzzing sound is another good indicator that you've got a defective wall switch. It can signal that the switch is going bad, but it can also signify a large load on the circuit. It could be because they're connected to large appliances, such as a pool pump or a refrigerator-freezer.

It's Too Sensitive

If the switch works initially, only to stop working after a light poke, it's a sign that it's gone bad. If it's too sensitive, it could mean that the connection is faulty or the screw terminals in the switch have come loose. If the screws become loose often, it's time to call in electrical services.

It's Stiff or Loose

If your wall switch is too stiff or loose to touch, it's a sign that it isn't properly secured. If the metal strips inside the switch are loose, it won't work or function properly. You may need to tighten the screws or replace the switch entirely if it's broken or damaged.


If you notice any of these signs, hiring professional electrical services to check your wall switch is a good idea. A simple repair could take an hour or two, but an electrical fault can take much longer. If you want to ensure your family's safety, it's best to hire a professional to do the work.
