In North America adouble pole single throw switch is usually used to disconnect a 240 voltload by disconnecting both hot supply wires. This is a safety procedure to prevent someone getting a shock when working on the load and thinking the supply is off just by opening the switch. Although just opening up one leg will turn the load off the remaining leg will still be "hot" to neutral and ground. The "hot" wires go to the top of the switch terminals and the load connects to the bottom two terminals on the switch.

How does a double pole switch work?
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.
