2 way switch wiring diagram is a basic electrical circuit that allows the switching of a light or other electrical appliance from two different locations. This is commonly used in Australian homes and commercial buildings where there is a need to control a single light from two different switch locations.
What is a 2 Way Switch?
A 2 way switch is a type of electrical switch that allows the user to control a light or other electrical appliance from two different locations. This is achieved by wiring two switches in parallel, so that both switches are connected to the same electrical circuit and can control the same light or appliance.
The two switch locations are commonly referred to as the “first switch” and the “second switch”. When the first switch is turned on, it sends an electrical signal to the second switch, which in turn activates the light or appliance.
How to Wire a 2 Way Switch in Australia?
Wiring a 2 way switch in Australia is relatively simple, and can be done by following the basic steps outlined below:
Step 1: Gather Materials
Before starting the wiring process, gather all the necessary materials including:
- Two 2 way switches
- Electrical cables (usually 1.5mm twin and earth cable)
- Junction box
- Screwdriver
- Wire stripper/cutter
- Electrical tape
Step 2: Turn Off Power Supply
Before beginning the wiring process, it is important to turn off the power supply to the area where the switch will be installed. This can be done by switching off the main power switch in the switchboard.
Step 3: Wire the First Switch
Start by wiring the first switch. Connect the incoming power supply (usually black or red wire) to the common terminal of the first switch. Then, connect the red wire to the “L1” terminal and the black wire to the “L2” terminal.
It is important to note that the colour coding of electrical wires may vary depending on the specific installation. Always refer to the installation guide or seek advice from a licensed electrician if in doubt.
Step 4: Wire the Second Switch
Next, wire the second switch. Connect the red wire of the twin and earth cable to the “L1” terminal of the second switch, and the black wire to the “L2” terminal. Then, connect the earth wire to the earth terminal.
Step 5: Connect the Cables to the Junction Box
Finally, connect the cables to the junction box. Strip the ends of the wires, and connect them to the appropriate terminals in the junction box. Use electrical tape to secure the cables and prevent any loose connections.
FAQs
1) What are the advantages of using a 2 way switch?
One of the main advantages of using a 2 way switch is that it allows for greater flexibility in controlling lights or appliances from multiple locations. This is useful in larger rooms or areas where there are multiple entrances or exits.
2) Can a 2 way switch be used with a dimmer switch?
Yes, a 2 way switch can be used in conjunction with a dimmer switch to control the level of lighting in a room. However, it is important to ensure that the dimmer switch is compatible with the type of light bulb being used, as some bulbs may not be suitable for use with dimmer switches.
3) Do I need an electrician to install a 2 way switch?
It is always advisable to seek the assistance of a licensed electrician when installing electrical switches or appliances. This can help to ensure that the installation is done safely and correctly, and can prevent any potential hazards or accidents.
Conclusion
2 way switch wiring diagram is a common electrical circuit used in Australian homes and commercial buildings. While the installation process can be relatively simple, it is important to follow the correct wiring procedures and seek the assistance of a licensed electrician if in doubt. By understanding the basics of 2 way switch wiring, you can gain greater control over the lighting and appliances in your home or workplace.
