what are your guys thoughts on the switch itself? If I read the site right, it looks like you have to move a tiny pin from one plug to another to turn the unit on and off? It doesn't read to me like this is a fail-safe switch...not to mention the thought of just a tiny pin keeping my airplane turned on makes me nervous. (Regardless of their note about how much force would be required for it to vibrate out)

Any other suggestions on a high-quality fail-safe switch??
