Want to do it yourself?

Replacing a light switch is an easy enough job that you can complete yourself (and it will definitely give your bragging rights!). So, let’s get to it.

Tip: Not sure what is a good replacement for your current one? Turn off the electricity, unscrew your switch, take a photo of the front and back of the switch and take this photo to your local hardware store for an exact replacement. If you want a different switch design, ensure that you choose a switch that has the right wattage for the wattage in your light fixtures.

Materials needed:

  • New light switch
  • Electricity detector/tester
  • Medium terminal screwdriver
  • Small terminal screwdriver

Step 1 – Safety.

Before touching any electrical work, you MUST isolate the electricity in the specific room you will be working on. Head to your fuse box and turn off the switch on that room light. If you are unsure which one is the right one or want some peace of mind, turn off all electrics. To do this, turn off the main on/off red switch.

Step 2 – Unscrew your light switch.

Remove the screws on the light switch and pull it from the wall. Take a photo of the back of your light switch to see the positioning of the wires before disconnecting.

Step 3 – Confirm wires are no longer live.

Use an electricity detector to double-check the wires are no longer live.

Step 4 – Disconnect the wires.

Again, if you haven’t – take a photo of the wires before disconnecting. However, do not assume that the layout of the terminals is the same for your new light switch.

If you have a 1-way light switch, you will most likely have two terminals: a terminal marked as “Common”, “COM” or “C” which is for the live wire and another terminal marked as L1 which is the output for the light fixture. On some switches that do not have a common terminal, the live wire terminal will be L1 and the neutral wire terminal will be L2.

You will most likely have a red (live wire) and a black wire (neutral) or a brown (live wire) and a blue wire (neutral). You will also have an earth cable (yellow and green wire) going into the earth terminal in the back.

Use a small terminal screwdriver to unscrew the wires.

Step 5 – Install the new light switch.

Get your new light switch and insert your live wire into the live wire terminal (if your light switch has a COM/COMMON/C terminal, insert it here. If not, insert it into the L1 terminal). Screw the wire into place. Then, insert the neutral wire into the other terminal and screw it.

Installing a metal light switch?

If you are installing a metal light switch, you must take an earth cable from the back earth terminal to the front of the switch plate to ensure the switch plate is protected against electric shock.

Step 6 – Screw it in place.

Push the light switch back, ensuring that the cables will not be in the way of the screws. Then, fasten the screws into place.

Step 7 – Test.

Turn the switches on in the fuse box and test the light switch.
