What is a single pole or double pole electrical switch?
If one switch can control one circuit for one operation, it is a single-pole switch. If it can control two or three circuits for one operation, it is a double-pole or a triple-pole switch. The switch contains one circuit with NO or NC contacts.
How does three way switch differ from a single pole switch?
Single pole and three pole switches look the same when installed but are used for different purposes. Closer inspection reveals that while a single pole switch has two terminals, a three pole switch has three. For more information on our switches please click here.
How to wire a single pole switch?
What You’ll Need:
- A small flat screwdriver.
- Non-contact voltage tester
- Flexible electric wire
- Wire nut (if needed)
- Cutting pliers.
What is the difference between single and double pole switch?
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.
Do I need a single pole or double pole light switch?
Single pole sockets are perfectly legal and are safe for many appliances, but it is safer to use double pole sockets. Therefore is always better to use double pole sockets in all situations.
How do I know if my light switch is single pole?
It is easy to identify as it has the least amount of wires connected to it and in the gang box. Since a Single Pole/Single Throw light switch only turns a light ON or OFF, it will usually have two screw terminals with the black Load/Line wires connected to it.
What is the difference between single and double pole sockets?
Single pole means only the PHASE is switched. Double pole means both PHASE and NEUTRAL are switched together; giving complete isolation to the appliance.
Can a single pole switch control two lights?
The answer is yes; one switch can turn on multiple lights. You can use two ways to make your switch control multiple lights. The most common way is to daisy-chain the light fixtures through connecting them with each other and hooking the first fixture to the switch.
Why would you use a double pole switch?
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. Single pole switch is referred as a single pole, single throw switch.
What does single pole mean?
A single pole switch has one input and one output, it has two states; “on” or “off”. They can be wired either normally open or normally closed and can be either latching or momentary. There are two types of single pole switch, these are “single-pole, single throw” and “single pole double throw”.
Are most light switches single pole?
Essential Light Switches The most common household switch, a single-pole, has two terminals and simply turns power on or off. A three-way switch has three terminals; a four-way has four.

What is a 2 pole switch?
What is a double pole switch? Double pole switches are connected to two separate electric circuits. They essentially contain 2 switches which are linked together and can complete the circuit either simultaneously or staggered.
How do you wire a 2 pole light switch?

What is a single pole light switch?
Simply put, the common simple light switches you see in your home are single-pole switches. They operate one circuit and offer a standard on and off function. Double pole switches are generally used to control 240V circuits and operate higher demand appliances and motors.
What is the black wire on a single pole switch?
If you closely look at a single-pole switch, you’ll see a pair of brass terminals and a ground screw. In a single-pole wiring system, the live hot wire is usually black and it connects to one side of the terminal. The outgoing hot wire attaches to the other end of the terminal.
How many amps does a double pole switch use?
A double pole switch is usually rated at 30 amps, twice than a standard switch rated at 15-20 amps. These switches make it possible to safely isolate appliances. As mentioned, double pole wiring is used for heavy-load appliances like showers and cookers.
Why do you need a double pole switch?
In higher ratings, a double pole switch is ideal because it has more room for thicker wires. In essence, wiring a single pole and double pole switch are similar. However, you have to keep in mind that the red wires go on one side of the switch and the black wires on the other.
How many hot wires are in a double pole?
Double pole wiring has four hot wires attached to it: two black and two red. One pair of black and red wire connects to the power supply’s switch. The other outgoing pair of wires feed the device. When the switch is toggled, the current is cut to both circuits at the same time.
What color are the terminals on a single pole switch?
Under the hood, single-pole switches come with two brass-colored screw terminals that connect to the power source wires. On a side note, the power source or hot wires are black in color. One of the terminals is for the incoming power source wire while the other terminal accommodates the outgoing hot wire.
What is double pole?
Essentially, a double pole is just two single switches together and can be controlled in two different locations. The idea is to connect the wire to just connect on one side and only one switch or location controls the circuit.
What is a double pole switch?
What Is A Pole? The pole of a switch refers to the amount of separate circuits that switch can control. Single pole switches can control just one circuit and a double pole switch can control two circuits. So a double pole switch is almost like having two single pole switches, controlled by the same switch.
Is a single pole socket cheaper than a double pole socket?
Whilst a single pole socket is generally cheaper it is always preferred that customers/electricians install double pole sockets for safer isolation of the plugged in appliances. What is the difference between a 2 pole and 3 pole switch? The difference is simply the amount of poles being switched. Double Pole Switches.
What does it mean when a double pole switch is rated higher?
The higher rating means that a double-pole switch has larger terminals to accommodate thicker wires. Advertisement. You wire a double-pole switch in essentially ...
Why are double pole switches used?
It's also because the wires feeding electricity to the switch are larger, and this is due to the fact that double-pole switches are usually used to control 240-volt circuits. Advertisement.
How many hot wires does a 120 volt switch have?
When you wire a switch to a 120-volt circuit, it functions to interrupt a single hot wire. It has only one pole, which is another way of saying it has a single pair of connection terminals. If you examine any single-pole light switch your house, you'll see its two brass terminals and the ground screw. The live hot wire, which is usually black, connects to one terminal, the outgoing hot wire connects to the other one and when the switch is off, the circuit is broken.
What voltage is between hot wire and neutral?
Circuits using only one hot wire need a neutral wire to complete the circuit, and the voltage between the hot wire and the neutral is 120 volts. The wiring standard was designed to make it possible to use both hot wires to power larger appliances that run more efficiently at 240 volts. A neutral wire isn't needed because ...
What happens when you flip a switch?
When you flip the switch, power is cut to both circuits simultaneously.
Do single pole switches have ground screws?
Neither a single- or double-pole switch has terminals for neutral wires, which when present are spliced together in the switch box and bypass the switch altogether. Both types of switches have ground screws because they must be connected to a circuit ground wire for safety. Advertisement. references.
Do you need a double pole switch for 240V?
If you want to switch a 240-volt circuit, you must interrupt both hot wires at the same time. That's why you need a double-pole switch, which is technically one that controls two circuits.
