“F4” adjustable pressure switches allow a micro-switch commutation once a preset pressure value is reached. The set point is adjusted working on the central screw (P3 execution) or intercepting the regulation dowel situated inside the instrument, using a 2mm hexagonal key (M2 and M3).


Rotating clockwise the set point is increased and vice-versa is decreased. Mechanical stops protect both the spring and the micro-switch from over pressurization.

Available with the parts in contact with the fluid in stainless steel or brass.


  • Wide adjustment range
  • Used for pumps and compressors
  • Small footprint, easy installation.
