Description
The Trane SWT03254 1/10 HP Pressure Switch 3F, 28 VA pilot duty, 24 / 120 VAC is an airflow safety control used in a furnace to verify proper inducer draft conditions in HVAC systems. It is installed in compatible heating equipment, where it monitors negative pressure created by the inducer motor and responds by opening or closing an electrical circuit once the required airflow level is reached. The switch is wired into the furnace control circuit and operates alongside the inducer assembly, ignition system, and main control board to confirm safe venting before burner operation.
