When it comes to electrical installations, proper wiring is crucial to ensure safe and efficient operations. One of the most common electrical devices found in homes and commercial buildings is the light switch. In this article, we will discuss the 1 gang switch wiring diagram for HPM switches. This guide will provide you with a step-by-step process on how to wire a 1 gang switch in your building or home.
What is a 1 Gang Switch?
A 1 gang switch is a single-pole switch that controls one lighting circuit. It has a single switch mechanism that controls one lighting point or fixture. The 1 gang switch is commonly used in rooms where there is only one lighting circuit, such as a bedroom, bathroom, or lounge room.

How to Wire a 1 Gang HPM Switch
Before you begin, ensure that you have the necessary tools and equipment for the job. These include:
- HPM 1 gang switch
- Screwdriver
- Wire strippers
- Electrical tape
- Electrical cables (1.5mm² twin and earth)
Step 1: Turn Off the Power Supply
Before starting any electrical work, turn off the power supply at the circuit breaker. This is to prevent electric shock or damage to the electrical system.
Step 2: Remove the Old Switch
If you are replacing an old switch, remove it by unscrewing the screws that secure it to the wall. Carefully pull out the switch and identify the wires connected to it. If you are installing a new switch, skip this step.
Step 3: Install the HPM Switch
Take the HPM switch and connect the wires to the appropriate terminals. The terminals are usually labeled “COM,” “L1,” and “L2.”
The “COM” terminal is the common terminal, and it is where the live wire from the electrical supply is connected. The “L1” and “L2” terminals are the switch connections, and they are where the live wire to the light fixture is connected.
Use wire strippers to strip the ends of the wires and wrap them around the terminals clockwise. Tighten the screws firmly to secure the wires in place.
Step 4: Test the Switch
After connecting the wires, turn on the power supply and test the switch to ensure that it is working correctly. Turn the switch on and off several times to verify that the light turns on and off accordingly.
Frequently Asked Questions (FAQ)
What is the difference between a 1 gang switch and a 2 gang switch?
A 1 gang switch controls one lighting circuit, while a 2 gang switch controls two lighting circuits. A 2 gang switch has two switch mechanisms and is commonly used in rooms with two light fixtures or circuits, such as a large living room or hallway.
What is the purpose of the common terminal in a switch?
The common terminal is the contact point that is connected to the live wire from the electrical supply. It allows the switch to control the flow of electricity to the light fixture by opening and closing the switch contacts.
Can I wire a 1 gang switch in a room with multiple light fixtures?
Yes, you can wire a 1 gang switch to control multiple light fixtures. However, you will need to connect the live wire from each light fixture to the switch and use a junction box to join the wires together. Alternatively, you can install a multi-gang switch to control multiple light fixtures separately.
Conclusion
Wiring a 1 gang switch may seem like a daunting task, but with the proper guidance, it can be a straightforward process. By following the steps outlined in this article, you should be able to install a 1 gang HPM switch quickly and safely. Remember to always turn off the power supply before starting any electrical work and test the switch after installation to ensure that it is working correctly.
