FUNCTION The pressure switch functions on the basis of the piston-spring principle. The microswitch (2) is actuated if the pressure lies below the configured value. The piston (6) acts against the spring plate (5) when pressure builds up. This braces itself against the continuously-adjustable compression spring (4). The piston (6) transfers the force of onto the spring plate (5) when the configured pressure is reached on the nozzle (7), enabling the microswitch (2) and triggering an electrical signal. The pressure to be monitored is determined by the preload tension of the spring (4). Adjustment is achieved by turning the adjusting element (3). Anticlockwise rotation reduces the switching pressure, while turning in a clockwise direction increases the switching pressure. The adjusting element (3) is fixed with the securing screw. A mechanical stop prevents the compression spring (4) from seizing due to excessive turning.
