Light switches are among the most important electrical fixtures in any residential or commercial building. They allow you to easily control the lighting in a particular space, while also helping to conserve energy by turning off lights when they are not needed. One of the most common types of light switches used in the UK is the 1 gang 2 way light switch, which allows you to control a single light fixture from two different locations. In this article, we will provide a comprehensive guide on how to wire a 1 gang 2 way light switch in the UK.
What is a 1 Gang 2 Way Light Switch?
A 1 gang 2 way light switch is a light switch that can be controlled from two different locations. These switches are commonly used in hallways, staircases, and other areas where it is convenient to control the lighting from multiple locations. A 1 gang 2 way light switch has two terminals, which are used to connect the switch to the mains electricity supply and the light fixture.
How Does a 1 Gang 2 Way Light Switch Work?
A 1 gang 2 way light switch works by using two switch mechanisms that are connected by a common wire. When one switch is turned on, it sends a signal to the other switch to turn on the light. This allows you to control the lighting from both locations, and ensures that the light is always turned on or off when you need it to be.
What are the Benefits of Using a 1 Gang 2 Way Light Switch?
There are several benefits to using a 1 gang 2 way light switch, including:
| Benefit | Description |
|---|---|
| Convenience | Allows you to control the lighting from multiple locations. |
| Energy Efficiency | Helps to conserve energy by turning off lights when they are not needed. |
| Improved Safety | Reduces the risk of accidents caused by fumbling for light switches in the dark. |
How to Wire a 1 Gang 2 Way Light Switch in the UK
Before you begin, make sure you have the following tools and materials:
- 1 gang 2 way light switch
- 2 core and earth cable (1.0mm or 1.5mm)
- Cable clips
- Screwdrivers
- Wire strippers
- Electrical tape
Step 1: Turn Off the Power Supply
Before you begin, make sure to turn off the power supply to the area where you will be working. This can be done by turning off the circuit breaker or removing the fuse from the circuit that supplies the switch.
Step 2: Remove the Existing Switch
Remove the existing switch from the wall by unscrewing the screws that hold the switch in place. Once the switch is removed, disconnect the wires from the terminals on the back of the switch.
Step 3: Run the Cables
Run the 2 core and earth cable from the first switch location to the second switch location. Use cable clips to secure the cable to the wall or ceiling.
Step 4: Connect the Wires
Connect the wires as follows:
- Connect the live wire (brown or red) to the common terminal (COM) on the first switch.
- Connect the live wire to the common terminal (COM) on the second switch.
- Connect the switched live wire (blue or black) to the L1 terminal on the first switch.
- Connect the switched live wire to the L1 terminal on the second switch.
- Connect the earth wire (green and yellow) to the earth terminal on both switches.
Step 5: Secure the Switches
Install the switches back into the wall and secure them in place using the screws provided. Turn the power supply back on and test the switches to make sure they are working properly.
