This pressure switch trips across a 360 to 1700 psi (24.82 to 117.21 bar) set range on a 5 A SPST contact with a 70 to 250 psi (4.83 to 17.24 bar) deadband. It connects through a 1/4" NPT Male port in a sealed industrial body. It suits hydraulic and high-pressure system protection and oem equipment pressure sensing.
