Controls an electrically driven air compressor in a power circuit when the adjustable threshold upon falling is reached and is set to turn off at 125 psi. The switch has screw terminal electrical connections and two 2-pole NC contacts open on rising pressure. The non-adjustable differential is 30 psi and the adjustable cut-out range is 70 psi to 150 psi. The switch has a 1/4 In. NPSF internal fluid connection and is suitable for use with a lower-horsepower motor with 1.5 HP or less.
