Honeywell Inc.has introduced the Micro Switch 1HP series pressure switch to monitor and react to gas pressure or liquid pressure in aerospace or military systems. Potential aerospace applications include indication of loss of pressure, validation of system pressure, and automatic shut off of electrical equipment. Potential military applications include monitoring hydraulic pressure and fire suppression on ground vehicles. The switch has a pressure range of 150 to 5,000 psi, and offers and a selection of fittings, electrical connectors, pressure set points and differentials. The 1HP also contains a subminiature switch for set-point precision and performance over temperature. The standard product is configurable for fast prototyping, development, and delivery lead-times. Honeywell's Micro Switch 1HP series pressure switches are DO-160 and U.S. military specification approved.
