I have wired a few lights with 2 switches, but now I have a location where I need 3 switches. I guess I need a DPDT switch in the middle with SPDT at either end. In Global House even getting a SPDT light switch is not easy. Staff didn't have a clue.
Plan B is push buttons with a latching relay, but that only got us blank looks. When I asked for relays all I got was the usual 'mai mee', even as I pointed at the rows of relays sitting in the display cases behind locked glass.
What is the 'correct' way of doing this and where can I get the bits?
