Pressure Switch

Aerotec - UD-122 - AF33 (600)-24272 Differential Pressure Switch A pressure switch compares the pressure acting on the area of a piston or diaphragm against an opposing spring force. Sometimes the opposing force is the buckling force of a thin disk. A differential pressure switch compares two different pressures acting on opposite sides of the same piston or diaphragm.
