Dont know if it is orientation sensitive.....when I land hard, the engine misses and I suspect that I have either relay bounce or this switch is bouncing.

you could make it kill the motor when the oil pressure dropped, but from the factory it a safety feather so the motor wont cut off. if the reg. fuel pump relay is working you can unplug this switch and it wont effect the running of the motor. sound like your main fuel pump relay may be bouncing.
