Poles, meaning when referring to pins on a switch

pins

What are the poles on a 9 pin switch; does this mean a row of pins, if so which direction? And also what do the poles represent, and is there so much different between a 6 pin and 9 pin switch other than the extra 3?

Here is the switch:

You will likely find that it matches the 3PDT column but this is not guaranteed so double check with a multimeter.

Hopefully this should make sense - the pole is the pin that connects to either of the other two pins in a single switch element. In the example above there are 4 switch elements all toggled together but, equally it could be a push button.
