Description
The Trane SWT01260 Limit Switch is an essential control component used in furnace and air handling systems to monitor operating temperature and protect the heat exchanger from overheating. It is to open the control circuit when it reaches approximately 200F and close again when it drops to around 170F, supporting regulation and safe cycling of the heating system. Mounted on or near the heat exchanger or air stream path, it interrupts system operation during excessive heat conditions caused by restricted airflow or blower issues in HVAC systems.
