Just looking to get someone's opinion on the legality or practicality of this circuit:
There was another question posted recently where someone was asking about the ability to switch a second light both independently and dependently of a three-way circuit. This was the first idea that came to mind, but I've never seen a circuit like this and could only imagine the headache trying to troubleshoot this if you stumbled upon it in the future. Basically a regular three-way circuit, but then connect a third switch in reverse with another source of power tapped from the common in.
| Circuit 2 Pos A | Circuit 2 Pos B Circuit 1 ON | L1 *, L2 * | L1 *, L2 * Circuit 1 OFF | L1 o, L2 o | L1 *, L2 o
I do not believe it is against code directly, but is there something prohibiting this setup? (Neutrals at each switch box, but I ignored that for clarity in the picture.)
