These pressure switches are durable, reliable electromechanical gauge pressure on/off switches that are available with either single pole single throw (SPST) normally open or normally closed circuitry, or single pole double throw (SPDT) circuitry. Their high proof pressure and burst pressure ratings can allow for use in many rugged applications that require the making or breaking of an electrical connection in response to a pressure change of the system media.



  • Through optional smart diagnostic technology, Honeywell pressure switches are able to detect failures such as open circuits, cut wires, worn insulation, and more
  • Optional smart diagnostic technology allows up to four segregated signal amplitudes to perform diagnostics and status
  • Pressure port snubber suppresses pressure spikes
  • IP67 sealing provides enhanced durability in harsh environmental and washing applications


  • Pressure switching set point range: 3.5 psi to 4500 psi
  • Proof pressure: from 500 psi up to 10,000 psi
  • Burst pressure: from 1250 psi up to 20,000 psi
