This pressure switch trips across a 180 to 3000 psi (12.41 to 206.84 bar) set range on a 5 A SPDT contact with a 50 to 400 psi (3.45 to 27.58 bar) deadband. It connects through a 1/4" NPT Male port in a sealed industrial body. It suits compressor and pump pressure protection and oem equipment pressure monitoring.
