The HPS Series are electromechanical gauge pressure on/off switches 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. They have a wide-pressure switching point range of 150 to 4,500 psi, a proof pressure rating of 10,000 psi and burst pressure rating of 20,000 psi. The switches operate within a temperature range of -40° to 120° C (-40° to 248° F). Switching point accuracy is ±2%, and switching capability is 5 mA to 5 A.
