Component Overview
A gage pressure switch monitors pressure referenced to ambient atmospheric pressure and actuates an electrical contact when the measured gage pressure reaches a preset value, providing indication, warning, or control within the sensors-and-switches domain. A diaphragm, bellows, or piston senses pressure against a calibrated spring, switching contacts at the setpoint to drive cockpit indication or system logic referenced to local ambient conditions. In service it experiences sensing-element fatigue and creep that shift the setpoint, electrical contact erosion, pitting, and oxidation raising resistance, and spring relaxation. Diaphragm rupture, vent-port blockage affecting the ambient reference, seal leakage, contamination, and corrosion are common failure modes producing calibration drift, chatter, or failure to trip, driving recalibration, contact and seal servicing, and setpoint and continuity verification.
