Pressure Switches Line Guide

Pressure Switches

Better under pressure. Rely on Honeywell pressure switches and vacuum switches to perform in critical applications that experience performance spikes and other extreme conditions. These switches sense a change in the pressure or vacuum and open or close an electrical circuit when the designated set point is reached.

Honeywell offers an impressive line:

  • Electromechanical gauge pressure on/off pressure switches
  • Single pole single throw (SPST) normally open or normally closed circuitry, or single pole double throw (SPDT) circuitry (pressure switches)
  • Compatibility with a variety of media
  • Compact size
