Joystick question - Single or Double pole

[AC.]

I need two small joysticks and am looking at this one at Happ:

What does the "Single or Double pole switched" mean?

[NoOne=NBA=]

Single pole means that it closes one switch when activated, like a lightswitch would.

Double pole means that it will close two switches when activated.
An example of this would be if you glued a popsicle stick across the lightswitch and fan switch in your bathroom.
Shoving up on the popsicle stick would activate BOTH switches at the same time.

Thanks!  So that means I only need a single pole switch, unless I wanted to control two functions at the same time.
