1 Way Light Switch Wiring Diagram UK

Light switches are essential in every household as they allow us to turn on and off our lights with ease. One of the most common types of light switch is the 1 way light switch which is used to control a single light or a group of lights from one location. In this article, we will provide you with a detailed guide on how to wire a 1 way light switch in the UK.

What is a 1 Way Light Switch?

A 1 way light switch is a simple on/off switch that controls a single light or a group of lights from one location. The switch has two terminals, one is for the live wire or the incoming power supply, and the other is for the load wire or the wire that goes to the light.

When the switch is in the up position, it is in the on position, and the live wire is connected to the load wire, allowing the electricity to flow to the light. When the switch is in the down position, it is in the off position, and the live wire is disconnected from the load wire, cutting off the electricity supply to the light.

How to Wire a 1 Way Light Switch

Before you begin wiring your 1 way light switch, make sure that you have turned off the power supply to the circuit that you will be working on. You can do this by switching off the main circuit breaker or removing the fuse that controls the circuit.

Step 1: Remove the Existing Switch

The first step in wiring a 1 way light switch is to remove the existing switch. Use a screwdriver to remove the screws that hold the switch in place and gently pull the switch away from the wall. Make sure that you do not damage the wires that are connected to the switch.

Step 2: Identify the Wires

Once you have removed the switch, you will need to identify the wires that are connected to it. There should be three wires, a live wire, a load wire, and an earth wire. The live wire is usually brown or black, the load wire is usually blue or red, and the earth wire is usually green or yellow.

Step 3: Connect the Wires to the New Switch

Now that you have identified the wires, you can connect them to the new switch. Connect the live wire to the terminal that is marked ‘L’ or ‘COM’, and connect the load wire to the terminal that is marked ‘LOAD’ or ‘1 WAY’.

If there is an earth wire, connect it to the terminal that is marked ‘E’ or ‘Earth’. If there is no earth wire, you can ignore this step.

Step 4: Secure the Switch in Place

Once you have connected the wires to the new switch, you can secure the switch in place. Gently push the switch back into the wall and use the screws that you removed earlier to fix it in place.

Step 5: Test the Switch

After you have secured the switch in place, you can turn on the power supply and test the switch. Turn the switch on and off to make sure that it is working properly. If the switch is not working, turn off the power supply and check that the wires are connected correctly.
