Ah, circuit logic.

Doesn't even look like a puzzle, just a demonstration of how it works.

What makes it rougher to understand(learn from) is that due to the OR gates in the first stage, any TRUE/ON will get carried to the next stage since the first layer has an OR gate and an AND gate in parallel.

The answer is to leave them all off. Or turn them all on.
Turning on either of the two to the right turns off the exit, and turning on at least one each of the other pairs turns the exit back on.[\spoiler]

Wait, how?

Turning on both switches on the bottom level pairs returns 1 on the AND and 0 on the OR. But the diagram is missing an intermediate gate to combine the outputs from the bottom level before passing them on to the next AND gate.

All you need to do is turn on either input in each of the two leftmost pairs.

Geh. Logic gates.

Gimme some pencil, paper and a can o' Sprite. It's gonna be a long night...
