Double pole switch wiring diagram light

A double pole switch can be used to control light and a fan or 2 lights on separate circuits. It is easy to wire a double pole switch to work as a single pole switch because only one side is used instead of both.

How do you wire a double light switch?

This side of the switch is the line side it's the side that has the two terminals jumpered. Together

How does a double pole light switch work?

A double pole single throw switch controls two circuits (poles) and has 2 states an “on” (closed) state and an “off” (open) state. A double pole single throw has four terminals in total, two inputs and two outputs which are all controlled by the same switch.

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 do I know if I need a single pole or double pole switch?

Single pole switches are more simple switches, used for applications where on/off is required. Double pole switches are more complex switches for more complicated applications. ... Single pole switches are often used for;

Light switches.
Home appliances.
Alarms.
Industrial Machinery.
Emergency stop switches.

When would you use a double pole switch?

The double pole diverter switch is used to divert two current lines to another pair of lines; its applications are in household appliances as well as in domestic and industrial electrical installations.

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.

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

How do you wire a 3 way double switch?

One. Common black terminal screw tighten firmly next loop the second black hot wallbox wire

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 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.

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.

How do you wire a L1 L2 light switch?

And an l2 at the bottom by pressing the switch you simply transfer the current from the common to

What are the 4 types of light switches?

Most of the common types of switches come in different styles, such as toggle, rocker, slider, or push-button. The style usually does not affect the switch function and electrical wiring, though it can make the selection process confusing.

What is the difference between a single pole and a double pole circuit breaker?

Single-pole breakers: Provide 120 volts, 15-20 amps and have one hot wire and one neutral wire. Double-pole breakers: Provide 240 volts, 20-60 amps and have two hot wires that share one neutral wire.

Why is the switch put in the live wire?

A switch or a fuse in an electrical circuit is always connected to the live wire so that the socket or appliance is not live when switched off.

What does double pole mean in electrical terms?

What does 2-pole mean? 2-pole means that the device plug is not earthed and it normally has two pins that transmit electricity. Originally, all electrical devices were fitted with 2-pole plugs, which means that the devices were not earthed and that all mains sockets were constructed for 2-pole plugs.

Is a double pole switch the same as a 3 way switch?

A double-pole switch allows you to control two separate circuits using the same switch, while a three-way switch allows you to control a single circuit from two different locations. A double-pole three-way switch is able to integrate both of these functions into one.

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 do you know if a light switch is wired wrong?

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.
