toggle switch question

I am looking at some 3 position toggle switches at radio shack.com and I noticed that they all have 6 screw terminals. how do you wire these up?

probably on-off-on.

wiring would be: signal-power-signal (ground is through signal wire to circuit)
sounds like they're just double to control 2 circuits.

Of course I could be wrong.

Or they could be that kind

It depends on how the switches are labeled as to how they're wired internally.

so is this the type of switch I need to wire up my fog lights to my head lamps and be able to turn them on without the head lights on at the same time? I know I need a 0n-Off-On switch but didnt know it would involve 6 terminals.
