Equivalent to two single pole double throw switches controlled by a single mechanism. Think about 2 switches controlled at the same time with 4 possible connections. 2 connections when up, 2 connections when down.
A single pole, double throw (SPDT) switch is a "regular" switch that has three points of connection. A pair of the switches (wall switches) might be used to turn on a single light from two locations that are removed from one another, like at either end of a hallway, a stairway or a walk-through kitchen. A diagram of two methods of wiring them up is posted at Wikipedia, and a link is provided.
A single switch controls two separate wires.
two separate switches that operate at the same time. each has n/o & n/c contacts through the common connecter
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.
A DPDT switch is a Double Pole Double Throw switch
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.
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.
If you need to switch 2 poles then that's what you'll need. Just don't get your wires crossed

A DPDT switch is a Double Pole Double Throw switch
For a single throw, double pole switch, each section is wired to the individual items to be controlled. For a double throw double pole (220) set up, both hot wires are run through the switch.
Double pole wiring is checked the same way as single pole wiring. When you turn the switch on and the device works, in effect the switch is checked.
A switch is inserted in series with a single wire. When the switch is on, it is as if the wire had not been opened to insert the switch. When the switch is off the wire is open and no current can flow. All a double pole switch does is allows you to switch two separate wires at the same time with the same switch action. A single pole switch just switches one wire.
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.

A double pole single throw switch. used to switch two lines at the same time.
In electrical terminology it is known as a single pole double throw switch.
ICDP Stands For Iron Clad Double Pole. It is also known as Main Switch. It contain two fuse. One is for phase wire and another is for neutral wire.
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.
"Double-pole" refers to the type of switch used to disconnect the cooker from the incoming household electricity supply. Only by using a double-pole switch can the cooker's connections to both the live (or "hot") and neutral supply wires be switched on and off simultaneously.
