Source1 2435272000 Air Pressure Switch -0.54 on Fall Spno

Product Description

The Source1 2435272000 is an air pressure switch designed for use in HVAC systems where reliable airflow detection is critical. This switch is rated at -0.54 inches of water column, activating on a fall in pressure, and features a single-pole normally open (SPNO) configuration. Air pressure switches are essential safety and control components in forced-air heating systems, furnaces, and air handlers. They monitor the pressure differential created by the inducer motor or blower, confirming that proper airflow is present before allowing the system to advance through its ignition sequence. Without a functioning pressure switch, the control board will not energize the igniter, protecting the system from unsafe operation. The Source1 2435272000 is a direct-fit replacement part built to meet the demands of professional HVAC technicians performing service, maintenance, and repair work. The -0.54 set point means the switch closes its contacts when pressure drops to that threshold, signaling the control board that the draft inducer has established the correct negative pressure in the flue or heat exchanger area. SPNO wiring makes installation straightforward and compatible with standard control board terminals found across a wide range of residential and light commercial heating equipment. Source1 parts are manufactured and sourced to match OEM specifications, making this switch a dependable choice for field replacements. HVAC technicians should verify the set point and hose port configuration before installation to ensure proper fit. This switch is compact and lightweight, designed to mount securely within the furnace cabinet using standard hardware.
