not robotics, but help would be appreciated

So is the purpose of this to control the lights from three different places? It would seem to me that there is something in the NEC book about doing this. It is similar to the 2 switche layout (like one at each end of a hallway) but with 3 switches. However, if this is what you are doing, I believe that there need to be lines tied between the switches.

If I were you, I would head to your local Home Depot and pick up a copy of the NEC (National Electric Code) Book. It is green, costs either $19.99 or $29.99, and is in the electrical section.

I also may be describing something that is totally different from what you are looking to do. Am I on topic???
