This high-performance Differential Pressure Switch is an essential air-proving component designed for HVAC and commercial cooling systems. Engineered to monitor the pressure variance between two points, this switch ensures optimal airflow and system safety by detecting changes across filters, coils, and fans. Featuring a Single Pole Double Throw (SPDT) contact arrangement, it allows for versatile integration into control circuits for both signaling and safety shut-off functions. Whether used for verifying blower operation or monitoring air filter status, this durable pressure sensor provides accurate, reliable performance to maintain equipment efficiency and prevent costly downtime.
