Wire a two switch light

We therefore take the live wire and divert this into the common terminal or switch one we run

Can a light have 2 switches?

Controlling a light with two or more switches A light or lights can be controlled by more than one switch. The usual practice in home construction is to use 3-way switches. "3-way" is the electrician's designation for a single pole double throw (SPDT) switch.

How does a light circuit with two switches work?

Electrically, a typical "3-way" switch is a single pole, double throw (SPDT) switch. By correctly connecting two of these switches together, toggling either switch changes the state of the load from off to on, or vice versa.

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 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.

Can two single pole switches control one light?

You can clearly see that flicking either switch causes the light to change its state from on to off

What are two switches that control one light called?

When two light switches control one light they are called a three-way switch. When four switches control one light they are called four way switching.

What's the difference between one way and two way light switches?

1 Way Switches: If a light switch is '1 way' this means it is just an on/off switch. This is the simplest type of switch that you can get. 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.

What is a traveler wire?

The black and red wires are "travelers" and are connected to the traveler screw terminals on the two switches. This provides two alternate pathways for hot current to flow between the switches—this is what allows the switches to turn the lights on and off in a flexible manner.

What happens if you wire a light wrong?

But here's the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

What is a two way lighting circuit?

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.

Is a double pole switch the same as a 4 way switch?

Double pole light switches, also known as a four-way switch, are two single pole switches put together. Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit.

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

Again, some makes of switch may have alternative markings such as L1 L2 and L3. This type of switch is used where two switches control one light, such as at the top and bottom of a stairway. It can also be used as a one way switch, by using the COM and L1 terminals only.

What Colour is a live wire?

Wire	Colour
Live	Brown
Neutral	Blue
Earth	Yellow and Green

What Colour wire goes into L1 and L2?

Live wire colour Nowadays, the standard indicates that, in single-circuit installations, the colour brown should be used. This cable is labelled as L. This colour also identifies the first live cable (L1) in a three-circuit installation, the following cables being black (L2) and grey (L3).

Does the black wire go to L1 or L2?

Function	label	Color, common
Line, single phase	L	black or red (2nd hot)
Line, 3-phase	L1	black
Line, 3-phase	L2	red
Line, 3-phase	L3	blue

Is L2 live or neutral?

L1 is live and L2 is neutral.

Does it matter how you wire a light switch?

It doesn't matter as long as you do it the same on both switches. So, if you connect it to the upper right terminal on one switch, connect it to the upper right terminal on the other switch. Connect the second traveler wire to the terminal opposite the red wire terminal.

What is the difference between single pole and double pole?

Both single pole and double pole switches can be either single or double throw. A pole refers to the number of separate circuits a switch can control, a single pole switch can operate one circuit whereas a double pole switch can control two circuits. A throw refers to how many positions can be activated by a switch.

How do you wire 12 volt lights with 2 switches?

1) Connect 12V from the battery to the middle connection of the nearest switch. 2) Run two wires to the second switch, one wire from top to top of the two switches. The second wire from bottom to bottom of the two switches. 3) A wire from the middle connector of the second switch goes to the +ve terminal of the lamp.
