HPS Series high-pressure premium switches are available with a two million life-cycle rating, IP67 environmental sealing, and multiple port and termination options that improve equipment uptime, simplify rapid design and assembly, and reduce total production costs. Switches are durable, reliable electro-mechanical 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. They are designed for use in rugged transportation and industrial applications that require the making or breaking of an electrical connection in response to a pressure change of the system media.
