This pressure switch trips across a 1 to 10 psi (0.07 to 0.69 bar) set range on a 5 A SPDT contact with a 0.75 psi (0.05 bar) deadband. It connects through a 1/4" NPT Female port in a sealed industrial body. It suits differential pressure monitoring in industrial systems and air handling and ventilation pressure sensing.
