SWITCH ASSY - PRESSURE (P/N m620-3-40) - As Removed

The m620-3-40 is a pressure-actuated switch assembly for aircraft hydraulic system monitoring. This Meletron unit closes or opens electrical contacts when fluid pressure reaches a defined setpoint, providing discrete on/off signals to annunciators and control logic. The switch monitors hydraulic system pressure and alerts flight crews or maintenance systems to pressure anomalies.

Installation requires verification of setpoint calibration and electrical continuity per aircraft maintenance manual specifications. Commonly used in general and commercial aviation hydraulic circuits.
