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.
When you want to control a load from only one location.
A TPST switch is an acronym for triple pole, single throw it allows three different sources of current to be switched off with the single throw of a switch.
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole 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 double pole switch is used when the voltage from two circuits has to be broken. An example of this is a 240 volt supply. A single pole switch is used where there is only a single supply voltage that has to be broken.
Single pole toggle 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.
Yes, If you only hook up two wire it will work as a single pole
A single pole switch controls a light or outlet at one location. A 3 way switch controls a light or outlet from 2 locations.
A TPST switch is an acronym for triple pole, single throw it allows three different sources of current to be switched off with the single throw of a switch.
Unless the switch has a light to indicate the switch is turned on, there is no neutral connection to a single pole switch.
single pole switch with sthetic diagram are hard to find these days

Used to operate a lamp from two different locations.
In electronics, an SPDT is a type of switch. It stands for "Single Pole, Double Throw." In America, it's known as a three-way 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.
single pole, single throw.
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.
