I have two reasons, I'm not sure if either are correct:
1) Current. The compressor draws over 20 amps, which is a good chunk of current. I don't think the pressure switch is rated for that.
2) Control-ability. There are a few rules to the effect that all control signals must come from the cRIO. This wiring would run counter to that.
