Trane SWT2535 Pressure Switch

Upgrade your system reliability with the Trane SWT2535 Pressure Switch, a genuine OEM HVAC control switch engineered for precise negative pressure monitoring in high-efficiency furnaces and air handlers. This single-pole single-throw (SPST) switch is calibrated to strict Trane HVAC replacement parts standards, featuring a set point of -2.04 Open / -2.33 Close (2.25" WC). As a vital safety component, it ensures the inducer motor maintains proper combustion airflow and vacuum pressure before allowing the ignition sequence to proceed. Designed to replace aging or failed Trane furnace pressure switches, the SWT2535 provides the exact electrical and pneumatic interface required to restore factory-spec cycles in American Standard and Trane equipment, eliminating ignition lockouts caused by drifted set points or diaphragm fatigue.

• OEM Precision Calibration: factory-set at -2.04" WC Open and -2.33" WC Close to ensure exact safety compliance and system sequencing.
• Cross-Compatibility: Direct replacement for Trane SWT02535 and SWT02006, supporting various ADX and ADY series gas furnace models.
• Rugged Construction: Built to withstand commercial and industrial HVAC environments, preventing premature switch failure in harsh venting conditions.
• Simplified Installation: Features standard terminals and dual hose ports for seamless integration with existing inducer housing and vacuum lines.

Is the Trane SWT2535 compatible with American Standard units?
Yes, as an OEM component, it is fully compatible with both Trane and American Standard furnaces that specify this pressure range and part number.

Does this switch include the mounting bracket?
This is the standalone pressure switch. Technicians should retain the existing mounting bracket or ensure they have a universal bracket for installation.

What are the symptoms of a failing SWT2535?
Common indicators include the inducer motor running continuously without ignition, or the control board flashing a pressure switch error code (typically 2 or 3 blinks depending on the model).
