A 3-way switch is also described as a single pole double throw, maybe that's where the confusion in terms comes from.
"Not sure how to answer because I don't know what you mean by double pole switch."
LD1, Maybe I was told wrong 30 years ago, I have a light switch at top of my stairs, I have another light switch down cellar/basement, when I flip the switch upstairs the lights come on, I go down stairs next to the outside door and flip the switch, the lights go off, then I go out side, now I know it's not a single pole switch, but is it a 3-way light switch or a 2 pole light switch?

NOT double pole.
3-way or
Single pole double throw
Either are correct.
It IS a single pole.
3-way or
Single pole double throw
Either are correct.
It IS a single pole.
"Nope not the same..".........................If this answer was any clearer than that, it would be water, but the explanation put's me in over my head and over my pay grade. I'll be re-reading this trying to understand it.
Confusion of terms is exactly right, in the last hour, my hair has turn 3-way double throw greyer
Ok, before my com. runs out of ink, have you ever heard of a "3-way or Single pole double throw" light switch with built in light so I can see it in the dark so I can find/see the light switch on when I come in from out side? Tied of grabbing turning banging everything else but the light switch when I walk in, or am I the only one in the world with this problem.

You're working with 3-way switches at the top and bottom of the stairs. 3-way switches are single-pole double-throw (either switch can supply power to the load)...as opposed to a standard switch which is a single-pole single-throw (only one switch supplies power to the load). Double-pole switches will switch two lines simultaneously...similar to a two-pole breaker, which is a 2-pole single-throw.
