On the Series 1630 our highest precision conventional large diaphragm pressure switch provides maximum dependability. In addition, it incorporates a visible set point indicator for maximum convenience. UL and CSA listed, FM approved for general service. Electrical capability of 15 A handles most small electrical loads. For use only with air or compatible gases.

Caution: For use only with air or compatible gases.

• Visible set point indicator simplifies operation and trouble shooting
• Large diaphragm provides low range accuracy providing precise control
• Current loads of up to 15 A supports most small electrical loads supporting a broader range of HVAC and Process applications without the need for additional relays and components
