3-way switch - powered switch in middle?


By the way, some have mentioned that this is such a common question but I don't find anything in this site or any other site on power coming in to the middle switch. Even sites with as many as 8 different scenarios don't cover this power-in-the-middle scenario.

Thanks, Code05 for the very useful switch diagram. Though I am not an electrician, I have decades of experience in electronics and the reminder that this is just a SPDT switch scenario makes it really easy to understand.

Are you saying you have a solution or not?

The way I've tried to keep it simple about multi-way switching is by remembering schematically the common of one switch takes the hot line power, and the common of the other switch gives the line power to the load. Then all the travelers connect to each other respectively, regardless of whether there are any or how many 4-ways in the middle.
So it doesn't matter where the line power enters into the picture; you just need to "get" the hot line to one 3-way switch and "get back" the neutral from the load (and per 2011 NEC, create the neutral "bus" among all the switches too).
