This 5/8-inch high-limit disc switch is a critical safety component designed for HVAC and furnace heating systems. As an automatic reset limit control, it monitors internal air temperatures to prevent overheating and potential equipment damage. When the system's temperature reaches the designated high-limit trip point of 200°F, the switch opens the electrical circuit to shut down the burner or heating element. Once the unit cools by 30°F, the switch automatically resets to restore standard operation. This fan disc switch is essential for maintaining safe operating parameters in residential and commercial forced-air heating units, providing reliable protection against airflow restrictions or blower failures.
