Murphy By Enovation PSB-100-F20 Direct Mount Pressure Switch – 20 Psi Trip Point, 0-100 Psi Range, SPDT 3A @ 30VDC, Brass Mount

About This Product

Need a reliable pressure switch for your engine or industrial setup? The Murphy PSB-100-F20 is built tough for critical pressure points. It's a direct-mount switch with a single SPDT (single-pole, double-throw) contact that can trigger alarms, indicator lights, or even shut down equipment if pressure gets out of whack. The trip point is factory preset at 20 psi falling (so it trips when pressure drops below that), and it handles a range of 0-100 psi – max pressure it can withstand is 200 psi. Built with a precision brass mounting plate, a beryllium copper diaphragm for quick response, and a removable brass pulsation dampener. The steel housing is sealed against moisture and dust, plus it's corrosion-resistant. Wiring is easy thanks to the glass-filled nylon terminal block with screw terminals. Connection is 1/8-27 NPT brass. Rated for 3A at 30VDC inductive loads. Perfect when you don't need a gauge reading but you absolutely need to monitor pressure for safety or efficiency. Great for industrial engines, pumps, or compressors in general purpose areas. No fuss, just a solid, weatherproof switch that does its job. Mount it and forget it – until you need it to act. A trusted Murphy part that'll keep your systems in check.
