A proper "3-way switch" would be capable of being switched to 3 different positions and could have one, two or more poles. Each pole could be either single- or double-throw.
"How does a single pole switch differ from a three way?" is a trick question often asked to catch-out new trainee electricians because the common but mis-named "three-way switch" is actually a single pole, double throw switch, i.e. it is only a 2-way switch, not a 3-way switch.
A pair of "3-terminal, single pole, double throw" switches are often used to hook-up two separate light switches to control one light or one set of lights.
The same answer put in a different way
Despite the fact that the name "3-way switch" is often used to describe it, if it is of the type that has just one pole that can only be physically switched 2 ways, the name "3-way switch" is quite wrong for that particular switch. A "3-terminal, single pole, double throw" switch" is a more accurate description for it.

What is the difference between iron clad double pole switch and double pole single throw 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.

A single pole switch is used where there is only a single supply voltage that has to be broken.

What is difference between single pole and double pole switch?
A single pole switch interrupts only one wire, which must be the live wire. A double pole switch interrupts both the live and the neutral, so it contains two separate switches operated by the same lever. Current practice is to use single-pole switches, to avoid a fault condition which could leave equipment live while switched off.
