The PSW-800 Series are economical pressure switches which feature an easy-to-adjust setpoint with locking set screw. They utilise a sealed piston or diaphragm-piston design, which is ideally suited for harsh environments. All models come with 300 mm (12′) colour-coded leads and a ½’ female conduit fitting for electrical connections.
