That's what a 3-way or 4-way (should be called X-way) switch setup is - three or four or more switches that no matter what the state of the light is, flipping ANY switch will change the state.

Sorry then, I misunderstood what you meant by:

> a path is always found on one flip of the switch

I thought you were taking the comment you replied to to be seeking a simple parallel arrangement of SPST switches, so that turning any one on would turn the light on.

So I was explaining that No, point is you want 'off' on any switch (regardless of the state of the others) too. Seems you understood that though. :)
