Descrição

The PSW9 Series pressure switches are used in OEM applications, hydraulic power units, heavy industrial, test equipment, and ship building. The compact modular design makes them useful for both mobile and stationary hydraulic applications. A SPDT micro switch will change state on increasing pressure at the setpoint, and will reset when the pressure decreases below the set-point by the amount of the deadband. The long pressure spring allows for a precise adjustable set-point. The PSW9 features a captive set screw for industrial applications
