# What is a triple pole single throw switch?

## What is a triple pole single throw switch?

Many people believe that the word “poles” when used for circuit breakers or switches refers to how many terminals are on the bottom. So if you have a triple throw switch it has 3 on positions. SPST simply mean single pole, single throw. The product controls one circuit with one On position.

What does single pole single throw mean?

A Single Pole Single Throw (SPST) switch is a switch that only has a single input and can connect only to one output. This means it only has one input terminal and only one output terminal. A Single Pole Single Throw switch serves in circuits as on-off switches. When the switch is closed, the circuit is on.

What is the difference between a 2 pole and 3 pole switch?

2-pole means that the device plug is not earthed and it normally has two pins that transmit electricity. Earthed plug systems are therefore known as 3-pole systems, even though this is not quite technically correct.

### What is a double pole single throw relay?

The Double Pole Single Throw DPST relay is the equivalent of 2 SPST switches (NO Normally Open and NC Normaly Closed) and can be used to switch 2 different loads. We have 2 scenarios depending on the type of relay. without voltage on coil: with a NO the loads will be OFF because the current cannot flow.

What is the difference between a single pole and 3 way switch?

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. You can usually replace any single-pole switch with a dimmer.

What does SPDT switch stand for?

Single Pole Double Throw
A Single Pole Double Throw (SPDT) switch is a switch that only has a single input and can connect to and switch between the 2 outputs. This means it has one input terminal and two output terminals. A Single Pole Double Throw switch can serve a variety of functions in a circuit.

## Is a 3 pole breaker 3 phase?

The three-pole breaker operates via the same method as a single-pole breaker. Used most often in a three-phase electrical system, a three-pole breaker connects three different conductors, such as is often required by heavy duty industrial motors.

What is the purpose of a single pole double throw switch?

A Single Pole Double Throw switch can serve a variety of functions in a circuit. It can serve as an on-off switch, depending on how the circuit is wired. Or it can serve to connect circuits to any 2 various paths that a circuit may need to function in.
