Warning Signs That Your Light Switch is Failing

Light switches play a crucial role in the electrical system of your home. They allow you to turn on and off light fixtures, and they control other electric devices such as fans and table lamps. If you notice that your light switch flickers or is warm to the touch, it might be a sign that its metal components are wearing out. This may indicate a dangerous situation and should be immediately repaired by an electrician.

Unlike other household items, light switches have been around for decades. Their mechanical design and appearance have changed slightly over time, but basic toggle and rocker switches still dominate the market. Regardless of the style you choose, there are certain warning signs that your switch is failing that should signal you to contact a local electrician as soon as possible.

There are several different types of light switches, each characterized by its unique look and functionality. These include single-pole switches, three-way switches, and smart light switches, which can be controlled with a home automation device or by voice commands (i.e., Amazon Alexa or Google Assistant). While a switch's appearance can influence your decision-making process, you should focus on its electrical features when choosing one for your home.

The type of switch you choose should match the voltage requirements of your electrical system, which can be found on the breaker panel in your house or garage. If the voltage is incorrect for the switch, it will not be able to perform its job properly and may cause an electrical fire or shock.

A light switch works by interrupting the flow of electricity between two electrical contacts. The toggle on the outside of the switch pivots on a spring and moves a lever on the inside, connecting or disconnecting an electrical path to the light fixture. When the switch is turned on, it creates an electrical channel between the contacts that powers the lighbulbs. If the switch is turned off, the contacts close, removing power from the lights.

Single-pole switches are the most common type of switch you'll find in homes, and they're easy to install. They have two brass terminal screws and a toggle labeled ON and OFF. One of the terminals connects to the incoming power-source wire, which is black, and the other connects to the outgoing wire that leads to your light fixture.

In order to properly install a single-pole switch, you must first shut off the power to the circuit that's being worked on at the breaker box. Once you've done this, you can begin removing the old switches from the wall. As you remove each switch, be sure to note how the wiring is connected so that you can replicate this setup with your new switch. When you've removed the faceplates of both switches, use a screwdriver to remove the existing screws and pull them out. After that, you can attach the wires to your new switch. Be sure to use a wire nut for each connection and to wrap the end of each wire with electrical tape.
