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
