Pressure Switches

Pressure switches that allow microswitch operation once a pre-set pressure is reached. K and K3 Series incorporate a mechanical stop providing over-pressure protection for the spring and microswitch. Electrical connections for all models to DIN 43650.


  • Observe switching range. Do not subject switch to maximum allowable pressure during normal operation. Short pressure peaks must not exceed this value.
