US Single-pole switchIn the US, the standard "single-pole" light switch is single-pole single-throw, with only 2 terminals. In the ON position it connects the two terminals, and in the OFF position it doesn't.

The standard US "3-way" light switch (used for switching a light from two different switches) is single-pole double-throw. It has 3 terminals (hence the term "3-way"), and it connects one of those terminals to either of the other two, depending on the switch position. There's no OFF position, so the switch has only two positions.

What is difference between single pole and double pole thermostat?

A single-pole switch is an on/off switch that switches a single wire such as the circuit to your overhead light. A double pole switch is also an on/off switch that switches two wires. You would use this to switch as 240 volt circuit (which requires two hot wires) or if you had two circuit you wanted to switch at the same time. I've used them when I had two large light circuits that required two breakers that I wanted to switch with one switch.

Answer for USA, Canada and countries running a 60 Hz supply service.The difference between a double pole switch and a single pole switch is the use of the switch in the installation or equipment.

What is a one pole 2 gang switch?

Typically the number of poles represents the number of sources being switched. In a normal household ON/OFF light switch the single pole is the HOT wire (Black). The most common single pole switch is also single throw. The ON/OFF switch described above. This switch is abbreviated SPST. You could also have a single pole double throw switch (SPDT). and other variants on the same theme. The term gang is usually used to describe multiple switches in the same electric box. For example, if you had 3 switches together with a single switch plate, the switch plate would be described as a 3-gang switch plate.


How can you tell the difference between a single pole and a double pole switch?
