In a home it could be used as a service disconnect for a 240V air handler in an attic. That's the only time I install double pole switches in houses. But they can be used for controlling any 240V load. Another application in a place with lots of lighting would be for controlling a multiwire lighting circuit in a retail store or something (suppose the 120V troffers are supplied by one 20A 3-wire circuit, so in effect two 20A circuits sharing a neutral). Of course, with that set-up you can use two single pole switches since there are no 240V loads but if you wanted all the lights on one switch that's how you'd have to do it unless you wanted to use a contactor, which will use additional power.

Please check out my newly-updated website! McCann Lighting Company is where my street light collection is displayed in detail.
