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.
