The Series DS-7300 Bourdon Tube Pressure Switch features a SPDT hermetically sealed snap action switch for applications where mercury is not acceptable. Hermetically sealed snap switches are an environmentally friendly alternative to mercury tube switches while still providing the improved performance of sealed contacts in industrial applications. The series DS combines extremely high sensitivity and great repeatability with an easily adjustable set point featuring an external adjustment and visible calibrated dial.
