The Oxygen Pressure Switch is designed for use in Oxygen Systems where the pressure is controlled in the range of 60-90 PSIG. If system pressure drops to 45-50 PSIG the switch sends a signal to an annunciator or EICAS computer, warning of low system pressure. The unit may be mounted “In-Line” in the system distribution tubing, saving weight, space, and leak points. The Oxygen Pressure Switch comes provided with mounting holes for bulkhead or panel mounting. Standard units provided with silver contacts capable of 2 AMP switching loads at 28 VDC. Also available on special order, gold plated bifurcated contacts for low level switching.
