Armstrong Furnace R45032-001 Pressure Switch 30067439-890 streamlining maintenance and replacement tasksThe Armstrong Furnace R45032 001 Low Pressure Switch is a critical safety component designed for precise monitoring of system refrigerant pressure. This SPST pressure switch operates on a 10 30# logic, functioning as a normally closed control that opens when pressure drops below the 10 PSI cutout setpoint and resets when pressure reaches 30 PSI. Engineered for compatibility with Armstrong, Air Ease, and Concord HVAC units, this low pressure cutout
