Cleveland Controls NS2-0544-00 Pressure Switch

The Cleveland Controls NS2-0544-00 is an industrial-grade differential air pressure switch designed for critical proof-of-flow and fan status monitoring. This diaphragm-actuated pressure switch is the direct manufacturer-specified replacement for the RSS-495-544, ensuring seamless mechanical and electrical compatibility. Built with a robust glass-filled polycarbonate housing, the NS2-0544-00 provides precise sensing of air and non-combustible gases in positive, negative, or differential pressure applications. Professional HVACR contractors utilize this switch for its reliability in furnace pressure switch troubleshooting and general ventilation safety interlocks. The unit features one-hole mounting bracket integration and standard spade terminals for high-speed field installation. Engineered for high sensitivity and repeatable setpoints, it is a staple component in Cleveland Controls air pressure sensing configurations, maintaining system integrity by detecting airflow failures or blocked flue conditions before they compromise equipment performance.
