Description
The Hubbell Industrial Controls 69WR7 Pressure Switch is a mechanical component used to monitor and regulate pressure levels in air and fluid circuits. It operates with a minimum closing pressure of 35 PSI and an upper opening threshold of 150 PSI, enabling controlled response based on system pressure changes. Within HVAC systems it is commonly integrated into compressors, pumps, and safety control lines to detect pressure variations and trigger switching actions for operational stability. The unit supports pressure-based activation and interruption of circuits, helping maintain proper equipment performance during routine operation and protective control conditions.
