What is a Single Pole Switch

What is a Single Pole Switch

A single pole switch is a simple switch often found in the home; they are easily wired and installed and are very common. Most of our switches are single pole.

What is a Single Pole Switch?

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”.

Poles and Throws

Pole – 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.

Throw – throws refer to many positions can be activated by a switch a single-pole switch will close a circuit in one position whereas a double though will close a circuit in two positions.

Single pole double throw switches are used in applications where an electrical device can be switched between “on” or “standby”. Single pole single throw switches are used in applications where the switch is either “on” or “off” – the connection is made or broken, including light switches.
