Has anyone ever considered having either a second switch, or a three-way switch, so that it would be possible to energize the general illumination circuit separately from the entire game? It's nice having the "ambiance" of the lights on but I wonder about leaving the always-on relays energized for no good reason. I can hear them buzzing faintly and I just know I'm burning life. Seems like it wouldn't be too hard to rig something up that wouldn't even have to be an irreversible change.
