I didn't check our pressure switch, but it's odd that everything works. The compressor turns on and off as expected, confirmed by the pressure gauge, and the compressor runs when the switch is not wired. That's why I thought the switch must be normally open, but reading the spec, it is normally closed. We're declaring the standard Compressor object and using m_compressor->Start(). Maybe the floating cRIO digital input is picking up noise and sensing it as a logic low, turning on the compressor?
