For one of my builds I've been thinking about making a PSU switch that allows power to be applied to one of two motherboards, so I can have 2 systems in one case.
I think I would need a 2 position 12 pole rotary switch to do this (since there are 12 leads on an AT power supply cable, and I have 2 states I am switching between).
It would probably be bad to switch between the 2 while the system was running, I can't imagine it would be good. Any thoughts on an interlock system to prevent that? Maybe a separate switch to arm the rotary switch? Once a motherboard is selected, if the interlock switch is active the rotary switch is either prevented from moving or moving it doesn't accomplish anything? I could rely on myself to not be stupid about it but I am absent minded and worry I might toggle it if the systems are actively running. Not likely, but possible. I don't have any children, but if I were to exhibit the system I can see little fingers finding that a temptation.
Good idea? Bad idea? Not practical without a lot of additional work/wiring (I am pretty confident I can wire up the switch without an interlock system, but not in my ability to design a proper interlock).
