If you’re looking for a guide on how to wire a 3 gang 2 way switch, you’ve come to the right place. In this article, we’ll walk you through the process step by step, with easy to follow instructions and visual aids. You don’t need to be an electrician to understand this guide – it’s written in simple, relaxed English. So let’s get started!
What is a 3 gang 2 way switch?
A 3 gang 2 way switch is a type of switch that allows you to control three separate electrical circuits from one location. The ‘2-way’ feature means that you can control each circuit from two different switches. This type of switch is commonly used in large rooms, such as living rooms, where one switch alone wouldn’t provide enough control over the lighting.
What is the difference between a 2 way and a 3 way switch?
The difference between a 2 way and a 3 way switch is the number of electrical circuits that it can control. A 2 way switch can control one circuit from two different locations, while a 3 way switch can control one circuit from three different locations. A 3 gang switch, as we mentioned earlier, can control three separate circuits from one location.
What do I need to wire a 3 gang 2 way switch?
Before you start wiring your 3 gang 2 way switch, you’ll need a few tools and materials. Here’s a list of what you’ll need:
| Tools | Materials |
|---|---|
| Wire cutters/strippers | 3 gang 2 way switch |
| Screwdriver | Electrical tape |
| Needle nose pliers | Wire connectors |
| Voltage tester | Electrical wire |
Step by step guide to wiring a 3 gang 2 way switch
Step 1: Turn off the power supply
Before you begin wiring your 3 gang 2 way switch, you must turn off the power supply to the room you’ll be working in. This will ensure your safety and prevent any electrical accidents.
Step 2: Strip the ends of the wires
Once you’ve turned off the power supply, use wire strippers to remove the insulation from the ends of the wires you’ll be connecting. Make sure you strip the right amount of insulation – too much or too little can cause problems later on.
Step 3: Connect the first wire to the first switch
Next, connect the first wire to the first switch. Take the black wire and connect it to the common terminal on the switch. This will be marked ‘COM’ on the switch.
Step 4: Connect the second wire to the first switch
Take the red wire and connect it to one of the two remaining terminals on the switch. This will be marked ‘L1’. The final terminal will be marked ‘L2’.
Step 5: Connect the first wire to the second switch
Take the black wire and connect it to the common terminal on the second switch. This will be marked ‘COM’ on the switch.
Step 6: Connect the second wire to the second switch
Take the yellow wire and connect it to one of the two remaining terminals on the switch. This will be marked ‘L1’. The final terminal will be marked ‘L2’.
Step 7: Connect the first wire to the third switch
Take the black wire and connect it to the common terminal on the third switch. This will be marked ‘COM’ on the switch.
Step 8: Connect the second wire to the third switch
Take the blue wire and connect it to one of the two remaining terminals on the switch. This will be marked ‘L1’. The final terminal will be marked ‘L2’.
Step 9: Connect the wires together
Take the black wire from the power supply and connect it to the black wire that you’ve just connected to the common terminals on each of the switches. Then, connect the brown wire from the lamp to the red wire that you’ve just connected to each of the switches.
Step 10: Test the switches
Before you turn the power supply back on, test each of the switches to make sure they control the right circuit. Turn the switches on and off to verify that everything is working correctly.
FAQ
Can I wire a 3 gang 2 way switch myself?
Yes, you can wire a 3 gang 2 way switch yourself. However, if you’re not comfortable working with electrical wires, it’s important to call a professional electrician to do the job.
What happens if I wire a 3 gang 2 way switch incorrectly?
If you wire a 3 gang 2 way switch incorrectly, it can cause electrical problems, including the switch not working at all, or even a fire. That’s why it’s essential to follow the instructions carefully and, if in doubt, seek the help of a professional electrician.
Can I use a 3 gang switch to control two separate circuits?
Yes, you can use a 3 gang switch to control two separate circuits. However, you’ll need to make sure that the switch is rated for the electrical load of both circuits.
What is the difference between a 1 gang, 2 gang, and 3 gang switch?
A 1 gang switch controls one electrical circuit from one location, while a 2 gang switch controls two circuits from one location, and a 3 gang switch controls three circuits from one location.
What is the difference between a 2 way and a 4 way switch?
A 2 way switch controls one circuit from two different locations, while a 4 way switch controls one circuit from four different locations. A 4 way switch is typically used in larger rooms or hallways where three or more switches are needed to control the lighting.
Can I install a 3 gang 2 way switch outside?
No, you should not install a 3 gang 2 way switch outside, as it’s not rated for outdoor use. Installing an indoor switch outside can cause safety hazards and damage the switch.
With these easy to follow instructions and our visual aids, you should now be confident in wiring a 3 gang 2 way switch yourself. Remember to stay safe and always turn off the power supply before working with electrical wires. If you’re unsure about any aspect of the wiring process, don’t hesitate to call a professional electrician to do the job.
