ok here is the deal i have a extra credit project due fo res. wiring class. and i am LOST. i need to hook up 6 switches with 6 lights, there can be only two lights on at a time when u turn on one switch it turns on the light in front and turns off the one in back off but leaves the light right above it on, like lights in a long tunnel. i can use any combination of the following single pole/double pole/three-way/four-way.
i kinda know u have to have three-ways at each end but after that i am very lost. any help would be greatly appreciated, thanks in advance
I have bad news for you....what you describe cannot be done legally these days.
The reason for this is that you end up switching the neutral wire, which violates the National Electric Code.
I concede that this arrangement was once common- but those were the days before polarised plugs, ground wires, PLC controls, and the like. I will admit that it worked extremely well- almost as if the lights "knew" which way you were walking.
Nevertheless, I think this is one clever electrical trick you don't need to know.

classicsat it has to be regular switches like found in every home out there and 6 cheap style screw in lamp holders. off all the things to have for extra credit i see in no way that this would ever have any effect on residetial wiring. i think he has to much free time on his hands to think this b.s. up

I think you could do it by using three ways so that the common is hot, one "traveller" srew goes to the bulb in front, the other srew goes to the bulb behind. then when you flip the switch it turns one off as it turns the next on. they would alternate having the one directly above on the sitch in front and behind. It could be done, it is a logic riddle. I'd need pencil and paper to really figure it out.
