2 gang light switch wiring

PIN1 & PIN2 of the first switch are connected with the PIN1 & PIN2 of the second switch respectively. One end of the bulb is connected with the Common Terminal of the second switch and another end of the Bulb is connected with the Neutral line of the AC power supply.

What does L1 and L2 mean on a light switch?

The other terminal is marked as L1 and is the output to the light fixture. When you're wiring decorative light switches such as chrome or stainless steel etc, you'll find that the switch will also have an L2 terminal which means it's a two way switch.

What does 2 Gang mean on a switch?

2 Gang Dimmer Switch. A 1 gang switch will control a single lighting circuit, and with a 2 gang switch you can control two lighting circuits, and so on.

What wires go where on a double light switch?

The 14/3 cable connects the 2 switches. The red wire connects the switches normally open terminals, and the black wire connects the normally closed terminals. And finally, the black wire of the light electrical box connects to the Up Switch common terminal.

What happens if you wire a light switch wrong?

If a light switch is wired up wrongly, a short circuit may takes place if you give phase and neutral to the switch terminals. Always connect neutral wire to the one terminal of the light and phase to the one terminal of the switch and off wire to the other terminal of the switch to the light other terminal.

What's the difference between 2 gang 1 way and 2 gang 2 way?

There are 3 basic types of switches that are used for domestic purposes: 1 Way Switches: If a light switch is '1 way' this means it is just an on/off switch. The single switch controls a single light (or lighting circuit). 2 Way Switches: A '2 way' switch means there is another switch controlling the same light.

Does the live wire go to L1 or L2?

Typically, these terminals will be marked COM and L1, or sometimes L1 and L2. Either way, it does not matter which wire is connected where. Usually the permanemt live (from the supply) is connected to COM and the switched live (to the lamp) is connected to L1.

Does neutral go into L1 or L2?

The faceplate of a single, one-way switch has two terminals: "L1" is the terminal to which the neutral core wire is attached - the blue wire (traditionally black, before the change).

What does L1 L2 L3 L4 mean on a light switch?

These have four terminals and are equivalent to two 2-way switches combined. There are various labelling schemes but L1, L2, L3, L4 is common. In one position L1 connects to L3, L2 connects to L4. In the other position L1 connects to L4, L2 connects to L3. Used where three or more switches control the same lighting.

Why are 2 switches wired together?

The black wire on the left side of the left switch is the switch leg for one receptacle, and the black wire on the right side of the right switch is the switch leg for another receptacle. The second wire connecting the two is simply there to bring electricity from the left switch's hot to the right switch.

How does 2 way light switch work?

2 way switching means having two or more switches in different locations to control one lamp. They are wired so that operation of either switch will control the light. This arrangement is often found in stairways, with one switch upstairs and one switch downstairs or in long hallways with a switch at either end.

Do you need a back box for light switch?

Back boxes are essential for a wiring installation, providing the rear housing required when fitting a switch or socket.

Does it matter where wires go on light switch?

Because the switch terminals are interchangeable, it doesn't matter which wire you put on each.

Where does each wire go on a light switch?

A standard single pole light switch will simply require you to attach the black (load) wire into it, and then the black wire leaving the switch and to your lights. The switch serves to cut the power from reaching the light switch. The white or neutral wire bypasses the switch and goes straight to your lights.

What Colour is a live wire?

Wire	Colour
Live	Brown
Neutral	Blue
Earth	Yellow and Green

How do you know if a light switch is wired correctly?

Test for Power Remove the screws on the switch cover plate, and pull off the cover plate to expose the switch wiring. Without touching any wires, test each wire in the electrical box with a non-contact voltage tester. Also, test each of the side terminals on the switch by touching it with the tip of the tester.

How can you tell if a light switch is wired backwards?

If either wire at the light fixture is still hot then the switch is wired incorrectly. If one of the wires is still hot at the light fixture with the switch in the off position, then you most likely have the light switch on the neutral wire.

What happens if you wire live and neutral wrong in a light switch?

There would be a shock hazard, and some devices might not work correctly. Depending on where exactly the wires are flipped, ground fault detecting circuit breakers may become ineffective. All around, this is a bad idea. Save this answer.

Can I use a 2 gang switch for one light?

A two way switch can be used as a one way switch or a two way switch. They are often used as both. In fact many electrical retailers (including Socket Store) don't sell one way switches as the price difference is insignificant and the two way will do the job for both.

Why is it called 2 gang?

"Gang" refers to the WIDTH of your electrical box and therefore the WIDTH of the cover plate. A single gang (or 1-gang) box is only wide enough for 1 switch or outlet. A double (or 2-gang) box holds 2 devices side by side.
