It's easy to make an all LEGO shut off switch. Use a Polarity switch and
a small cylinder. Use elastic bands to hold it to offset the air
pressure. When the pressure is enough to push the piston up it toggles
the switch and cuts the power. Works very well, if your interested I
could take pics of my auto shutoff and 4 piston compressor.
