The 1004478 is a hydraulic pressure switch that opens or closes an electrical circuit when system pressure reaches a preset threshold. Using a piston or diaphragm sensing element, it monitors hydraulic fluid pressure in aircraft systems. Commonly installed in landing gear circuits to signal pump cutoff, actuator status, or system faults.
The switch interfaces with cockpit warning lights, pump motors, and control logic to maintain safe hydraulic operation. Installation and pressure adjustment must follow the Aircraft Maintenance Manual and be verified against the Illustrated Parts Catalog for your specific aircraft.
