I have an idea to use a Blue-system bi-stable solenoid https://www.bluesea.com/products/category/20/95/Solenoids/ML-Solenoids
From my point of view, a bi-stable solenoid is much safer device compared to a regular solenoid. It doesn't consume any power. it will keep contacts connected even if the coil will fail. I mean - if you started the engine on the ground then you should worry about this solenoid during the flight.
Am I wrong?
Here is a manual
