Product Overview
1638-10 is a series 1630 large diaphragm pressure switch. It incorporates a visible set point indicator for maximum convenience. UL and CSA listed, FM approved for general service. Electrical capability of 15A handles most small electrical loads. For use only with air or compatible gases. Current loads of up to 15 amps supports most small electrical loads supporting a broader range of HVAC and process applications without the need for additional relays and components. Typical applications include damper positioning, air conditioning, duct air control and industrial service.
