Another problem with the coast system is that you can't add a 4-way switch without redoing the whole thing. Or at least I can't figure out a way to do it.
So has anyone else figured out a method for more than two locations, or a four-way? I am a little hung-over from a wedding last night, and just can not grasp the concept.
I have. You can insert one in the travelers in the usual way, as long as it's done at either end, i.e., between the lamps and either (or both) of the 3-ways.
If you place a 4-way between the lamps, then one will stay on all the time with the 4-way in one position.
