Joystick question - Single or Double pole

(1/1)

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.

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