The Trane SWT04195 High Limit Switch is a protection control component used to monitor temperature within heating equipment and interrupts electrical circuits when excessive heat is detected in HVAC systems. It has opened at 275F and resets at 245F after cooling. It is used in furnaces, air handlers, and packaged HVAC units where over-temperature protection is required. It protects heat exchangers and surrounding components from thermal damage. It operates as part of the system circuit, ensuring controlled shutdown and automatic recovery during temperature fluctuations in the systems.
