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.

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 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.
What is the difference between a single pole and a double pole switch?
One pole connects and disconnects one wire and double pole connects and disconnects two wires.
What is the difference between single pole double throw switch and single pole single throw switch?
Single pole, single throwA single pole, single throw switch can be operated to send current only to one other part of a circuit.So it can be used to switch something on or off.Single pole, double throwA single pole, double throw switch can operate to send current either to one part or to another part of a circuit.So it can be used to switch something on whilst switching something else off, or vice versa.Manually operated switches and electrically operated relays are available as "single pole, single throw", "single pole, double throw", "double pole, single throw", "double pole, double throw" and in many other variants of poles and throws.
What is the difference between a single pole switched socket and a double pole switched socket?
The term refers to whether the switch just acts on the live supply in the socket (single pole), or the live and neutral (double pole).
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.

How can you tell the difference between a single pole and a double pole switch?
Not counting ground terminals, a single pole switch will have either 2 or 3 terminals, depending on its design. Again, not counting ground terminals, a double pole switch will have 4 terminals.
What is the difference between a single pole and a double pole switch?
One pole connects and disconnects one wire and double pole connects and disconnects two wires.

What is the difference between single pole switch and a three way?
A single pole switch controls a light or outlet at one location. A 3 way switch controls a light or outlet from 2 locations.
Difference between TPN switch and TP and N switch?
no difference whatsoever
What does spdt switch stand for?
Single-pole, double-throw. The switch directs a single input to two possible outputs.
Can a double pole single throw switch be used instead of single pole switch?
Yes, but to do so is a waste of time and materials. Single pole switches are not expensive, buy a new one and replace it. A double pole switch is about five times the cost of a single pole.
Single throw double pole?
A single switch controls two separate wires.
