Description
The Trane SWT03374 Low Pressure Switch is a sensing component that responds to pressure conditions. It opens at 50 PSI and closes at 70 PSI allowing the control circuit to react to changing refrigerant or airflow pressure levels. When pressure drops below the set point the switch opens to interrupt operation and when pressure rises back to the recovery level it closes to restore circuit continuity. It is applied in refrigeration and air handling sections where pressure monitoring is required to maintain a stable system and protect internal components from abnormal operating conditions in HVAC systems.
