David98 posted:I read an article years ago, I believe in OGR, about what seemed like a very good idea - having a master power switch by the main entrance to the train room connected to a red light - sort of like an "On Air" light for a radio station - which would control power to the whole train room, to avoid any risk of leaving on the odd transformer, soldering gun, accessory, etc. May have worked through a relay to control multiple circuits. Seems like a good idea for safety and convenience. Would work for lights, too.
Like this...????
