Trane SWT1403 Low Pressure Switch 7 PSI Open/22 PSI Close

The Trane SWT1403 is a Low-Pressure Switch that is designed for use only with Trane heating and cooling equipment including furnaces and air conditioners. This safety device monitors the air pressure of the system all the time. The switch makes the furnace or air conditioner shut down in cases where the air pressure is low and becomes dangerous to the equipment. The dangers of damaging the compressor and other elements that need proper airflow are eliminated. The efficiency and reliability of your Trane HVAC system are also improved by the low-pressure switch, which provides safety and prevents costly repairs.
