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 amps 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
