    Sigma-Netics has been a leader for over 30 years in pressure sensing technology meeting industry's most demanding requirements. Product availability for pressure switches range from vacuum to 6000 PSIG; pressure transducers range from 0 to 9000 PSIG.

Pressure Switch Features

  • Coil Spring Design
    - High Spring Load combined with low spring rate
    - High Spring Load combined with low dynamic mass

  • Piston Actuation

  • Sigma-Shoe Teflon Dynamic seal

  • Positive mechanical stop

  • Stainless steel housing

  • Cushioned Actuation

  • Pressure Snubber

  • Compact Size

  • Diaphragm Actuation

  • Spring Loaded overtravel

  • DIN Connector


  • Repeatability and accuracy of actuation pressure
    - High resistance to vibration and shock (eliminates contact chatter and false actuation) 

  • Pressure signaling to 6000 PSIG 

  • Eliminates stick friction and "O" Ring pumping action 

  • High over pressure capability 

  • Corrosion and abuse resistant 

  • Converts a "hammer blow" to a "rubber mallet blow" on micro switch, prolonging switch life 

  • Eliminates the effect of pressure spikes and pump ripple 

  • Ideal for tight space and manifold applications
