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.

Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.

This is the typical light switch in your home that controls a single light from a single location. Sometimes you might see it described as SPST or single pole single throw.

A single pole single throw switch (SPST) is used to open or close a contact to a single wire. It can be used as an on/off switch for an appliance or for a light bulb.

A single pole switch controls a light or outlet at one location. A 3 way switch controls a light or outlet from 2 locations.
