Double light switch diagram

Off the ends of each of the black wires. Here's our switch again we use one switch to control the

What is L1 and L2 on a double 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.

How does a double light switch work?

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.

How do you wire a double light switch UK?

Now you're ready to change your switch the best way to do this is place the new switch up against

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

What happens if you wire a switch wrong?

Wiring a smart light switch wrong can result in the switch not working correctly. If the wiring creates a short circuit, it can lead to damage to the switch and/or a burnt-out fuse. Errors can also lead to electric shock, fire, and a violation of local wiring codes.

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.

Which is live 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.

Is L1 black or white?

120 V Connector	240 V Connector - 4 pin
Hot	Black	Hot L1
Neutral	White	Hot L2
Ground	Green	Ground

How do multiple light switches for the same light work?

Two separate light switches are able to control a single light through the use of special electrical wiring and a three-way switch. A three-way switch connects the two switches and the light together, creating an uninterrupted, but controllable, circuit amongst all components.

What is a double switch electrical?

Double switching, double cutting, or double breaking is the practice of using a multipole switch to close or open both the positive and negative sides of a DC electrical circuit, or both the hot and neutral sides of an AC circuit.

What is a dual control switch?

Dual control switches are the double pole type switches which are generally used at the top and bottom of a staircase, or at the opposite ends of a long corridor, etc. With such switches, the appliance (say, a bulb) can be switched on or off from, two different places.

Where does the black wire go on a double light switch?

The electrical power black wire connects to the Down Switch common terminal. The power white wire does not connect to the switch at all but is connected to the white wire of the 14/3 cable. The wire connection is completed inside the switch electrical box.

Can I change a single light switch to a double UK?

Depends wether or not you have a nuetral in the light switch, If it has been originally wired with the feed through the switch then yes. If the feed goes to the light and just a switch wire to the switch(Perminent live, Switch live & earth) then you will have to install a nuetral to either the switch or outside light.

What Colour is a live wire?

Wire	Colour
Live	Brown
Neutral	Blue
Earth	Yellow and Green

What Colour goes to 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).

Is L2 live or neutral?

L1 is live and L2 is neutral.

What is L1 and L2 on a wiring diagram?

L1 and L2 represent the two poles on an AC power supply. L1 and L2 provide power to the components on the line side of the circuit. The control side of the circuit will not have lines for L1 and L2.

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.
