DESCRIPTION
This pressure switch plays a critical role in sensing system pressure and delivering a definitive on/off signal to control circuits or indicators. Built for rugged environments, it features a sealed housing to resist moisture and dust ingress, and electrical contacts designed to withstand heavy cycling. Its threshold is calibrated to deliver reliable activation without false triggers, maintaining system safety and performance in braking, hydraulic, or air circuits. Proper installation ensures a leak-free seal and correct thread engagement for consistent readings. Regular inspection of electrical connections and seals helps maintain responsiveness and reliability. Source One Parts Center.
