Also, I was watching the Astronaut Farmer last night on PPV and saw the little hard wire loops that where installed next to the switches on each side of the individual switches in his space capsule and this reminded me of the ones NASA used to use....maybe still do.  Donno.  These seem to be just half circles that make grabbing the switch very deliberate and minimizes potential knocks.  Finally, it seems as if I have seen bars held in by springs that lay across a series of switches to keep them in place. 

 

What say ye?  Insight?  Wisdom? Warnings? Observations?  WAG's?

 

Thanks.

 

All the best,

There are switches that must be pulled out before they will move from one position to the next. Also the guard may be formed by cutting half circles from a narrow aluminum "U" channel. So both sides of the switch are protected. Then just a conventional switch may be used. There may be an AN drawing number for those guards.
