This pressure switch trips across a -30 to -1 inHg (-1.02 to -0.03 bar) set range on a 5 A SPST contact with a 1 to 4 inHg (0.03 to 0.14 bar) deadband. It connects through a 1/4" NPT Male port in a sealed industrial body. It suits harsh-environment industrial pressure monitoring and pump and compressor control.

The PSW-800 Series comprises economical pressure switches that feature an easy-to-adjust setpoint with locking set screw. They have a sealed-piston or diaphragm-piston design, ideal for harsh environments. All models come with 12" (300 mm) color-coded leads and a 1/2" female conduit fitting for electrical connections.
