I'm trying to connect two separate circuits from a single power source using 3way switches. My trouble seems that my wire from my light and my power source are in the same box. Is there a way to do this? I have wired it multiple ways and I keep getting the first switch almost Ike a master that needs to be on for the second circuit to work.
You need 14-3 or 12-3 going to each switch from the light/power:
Call the switches L(eft) and R(ight):
Connections at L switch:
Connections at R switch:
Our own BMitch provided an answer and diagrams here (originally found here). We differ slightly in wire assignments (mine's better ;-)(why? both switches have the same wire assignments, the magic happens at the light)), but its basically the same.
