I'm trying to figure out a way to have:
3 banks of lights, each with individual switches for ON/OFF independent of master switch position.
One master ON/OFF switch that HAS to turn all other switches off, but not necessarily ON.
Workshop with 3 worktable lights and various corners of shop. I want to be able to turn each work light on as needed without turning the others on, but want to be able to turn all off at the end of the day with one switch by the exit. In the morning when I return, if I forget to turn the master switch "ON" I would like to still be able to turn the work lights on without having to go back to the master switch. Is this possible with out relays? Some sort of fancy 3-way switch matrix?
