Hi Bob (et all)

I've been thinking of using this system (RV9a)
http://www.aeroelectric.com/articles/avmaster.pdf
for a avionics switch - would it be 'acceptable' to use a two pole, changeover (2-10) switch, as neither circuit would/should be on together, so: centre all off, switch up, avionics live, switch down, endurance bus feed live

I'd rather you use two separate switches.
No single point of failure. Having ALL switches
on at the same time poses no hazards.

Hi Bob

I know what you are saying about single point of failure, but a two pole swtich, with both sides failing, I fly a forty plus year old C172 (keeps me current while I build the RV) has switches which are very 'wobbly' and I presume they are original, but still doing their job - A good MS (Hamilton) switch should have some longevity built in I hope
