The Nasson pressure switch is not able to handle the current of a compressor. As Erik pointed out, the start current is 25 amps and run current is between 10 and 12 amps. More importantly, however, is this...

<R78> The Nason pressure switch must be connected to the high-pressure side of the pneumatic circuit (i.e. prior to the pressure regulator) to sense the “stored” pressure of the circuit. The two wires from the pressure switch must be connected directly to a digital input and ground port on the Digital Sidecar, and the cRIO-FRC must be programmed to sense the state of the switch and operate the relay module that powers the compressor to prevent over-pressuring the system.
