Wire two starter contactors in series. They will be energized by two momentary push button switches, one labeled and in plain sight on the panel, the other switch hidden. When the barefoot bandit attempts to steal my plane, he will turn on the master and push the start button. He will hear one contactor pull in and assume there is an electrical problem because the engine does not crank. So he will go find another plane that someone left the key in. > I will not need a key or an expensive key switch because only I will know how to start the engine (along with everyone else on Aeroelectric). And I will not have to worry about losing the key or forgetting it. Has anyone ever driven all of the way to the airport, only to realize the aircraft key was still at home? > Joe > Interesting. 1. You may need three pushbuttons (or more hands): two switches that individually should not work (test) and a third that operates both relays. 2. Light weight Rotax relays (if procured from Rotax) may not be cheap.

Even aircraft down to the size of the venerable DHC beaver. Of course if you steal one of those you better know what you are doing.
