How Do I Fix a Light Switch?

Learn How to Fix or Replace a Single-Pole Light Switch

Many homeowners are wary of doing their own electrical lighting projects, mainly because they don't understand the wiring behind the switch plate and are afraid of getting a shock.

It's actually not difficult to learn how to fix a light switch, and once you learn, you can also replace switches with dimmers if you desire.

A single-pole light switch is the most common type of light switch in a home. It is used to control one or more lights or fixtures from a single location.

A single-pole switch is different from a three-pole switch, which controls lights or fixtures from multiple locations (for example, from the top and bottom of a flight of stairs).

A single-pole light switch is the most common type of light switch in a home. It is used to control one or more lights or fixtures from a single location. A single-pole switch is different from a three-pole switch, which controls lights or fixtures from multiple locations (for example, from the top and bottom of a flight of stairs).

A single-pole switch has "on" and "off" designations, making it easier to determine the type of switch. If you have a single-pole switch that has failed, it's not difficult to replace it yourself.

Start by turning off the power to the switch. The main circuit breaker (or fuse panel) will contain separate switches that will be marked to designate the room to which each supplies power. Once the power to the light switch is turned off, remove the switch plate. Use a voltage tester to ensure the circuit is no longer live.

Unscrew the switch from the electrical box and pull it out of the wall with the wires still attached. You'll only be concerned with the wires connected directly to the switch. Compare the new switch with the old one to find the corresponding locations for the electrical screw connectors. Unscrew and connect one wire at a time, matching up each colored screw on the switch with the same matching colored wire from the wall. To connect each wire to the terminal, strip off 1/2 inch of insulation with a wire stripper and twist the ends in a loop with long-nose pliers. Hook the wire clockwise around the screw so when you tighten the screw it wraps the loop tighter.

Gently place the new, wired switch back into the electrical box and screw it into place. Attach the switch plate and turn the power back on. For assistance, or for more information about how to replace a single-pole light switch, please give us a call.
