Ok. I figured-remembered the trick. Once you see the trick you should be able to get it pretty easily.

Trick in White:
<font color="white"> The A switch is the Info-Switch and the B switch is the Noise Switch. If you want to do nothing you Flick the B switch.

Now, the Trick is you only let One Person Flick the A Switch Up. I think you would have to assign somebody that job. After he switches it Up, everybody else is only allowed to switch it Down. The Assigned Prisoner keeps count. He is the only one who Flicks the Switch more than once and he only Switches it back to the Up (Neutral) Position.

It's much easier to Figure-Remember than it is to Figure.
