Normally it is used for switching 240v, though there might be 120v
applications where you need to break the neutral also.

You can use it as a single pole switch if you have no use for a double.

I bought a Double pole switch. Why, I don't know. I looked in my trusty
electrical handbook and my copy of the 2007 NESC handbook (to most wasted
$65.00 I've ever spent) and nowhere is there a reference to a "Double Pole
Switch". So, what is a "Double Pole Switch" and what is it used for.

I've used many a single pole switch and a number of 3 way switches in my
time but this one's got me a bit baffled.

TIA
