How to change a light switch?

If a switch light becomes loose or doesn't work it can create a huge problem. A few days back, my switch became loose and the light was turning by itself ( since the switch was loose). It would disturb and irritate me at night. I finally decided to solve the problem by purchasing a new light switch. I had very little idea about how to replace old light switch so I decided to call my brother who has a decent knowledge of electrical works. He shared an effective guide on how to change a light switch in an old house. I followed what he said and I could successfully replace the switch. So, I will share the guide with you.

How to replace a light switch?

To replace the switch you need to remove the wires. For this, you need to insert a blade of the screwdriver into the hole where the wire is inserted and you need to lose the wire by pulling gently. 

Before dealing with the wire you must learn that the white wire connecting with the silver screw is the neutral wire. The black one that goes to the copper screw is the hot wire. It is at times red in colour. The green one is the ground wire attached to the green screw terminal.

To replace a single switch check out the guide below:

1. Turn the power off at the main circuit breaker.

2. Unscrew and remove the plate. Turn on the voltage tester to become sure that there is no circuit.

3. Unscrew the switch and take it out of the wires.

4. Check the new switch and compare it with the old one. After comparing you will find the locations for the electrical screw connectors. Since the power is off you can attach the connectors easily.

5. After placing the wires in the right place, gently push the wired switch back into the electrical box and screw it properly.

6. Turn on the power to check the light is working properly.

Before rounding up I will suggest you hire an electrician to do the job if you have less idea about electrical works.

This was all about how to change a light switch. I hope you find this informative.
