How to Replace a Light Switch

Learn how to replace a light switch with this informative video from Lowe's. Replacing a light switch has never been easier with these simple how-to steps. If your light switch is not working, you may need to replace it. If all the other lights on the same circuit are working, you may have a broken light switch. Before you begin, turn off the circuit breaker switch and label it with a piece of tape or a note to prevent anyone from turning it back on while you work. Make sure the power is off by removing the switch from the wall and place a circuit tester up to the wires. After you confirm the power is off, unscrew the wires from the broken switch. Take your new switch and make sure it is facing right side up and connect the wires. Use electrical tape around the light switch and wires for extra insulation. Screw the switch into the wall and restore power at the circuit breaker. Test the light switch, and if the light turns on, you can attach the cover plate. Now your light switch replacement installation is complete. Light Switches Product Link: Check out more useful how to videos at For more simple DIY projects, visit
