Description
The Trane SWT3374 one of the low-pressure switches that are utilized in many equipment, It constantly monitors air pressure in the system; it is a safety device. This opening eliminates all possibilities of damaging the low airflow situations by interrupting the electrical connection and thus stopping the system. On the other hand, when air pressure is beyond another pre-set limit, 70 PSI in this case, contacts come together to complete the circuit, and normal functioning of the system is restored. In any case, the Trane safeguards the HVAC system by providing correct air pressure ranges which promotes safe and useful operations.
