Honeywell's 5000 Series Ultra Duty Pressure Switch is engineered to withstand demanding conditions common in braking, transmission, and hydraulic systems. This switch addresses the challenge of sudden pressure spikes and high system pressures that can lead to premature failures in standard switches. The strengthened design incorporates a plated steel base and screw-machined components in a robust 3-piece construction. Modifications to the pressure cavity's effective area, along with improvements to the diaphragm button and diaphragm o-ring, enhance the switch's ability to handle pressure transients. The switch's compact size (2.3” height, 1.47” diameter) makes it suitable for space-constrained applications. It boasts a significantly increased burst rating, exceeding 4000 psi, compared to previous models.
