This high-quality high limit control switch is a vital safety component for HVAC systems and furnaces. Designed as a thermal fan disc, this switch monitors the temperature within the heating chamber to prevent system overheating. If temperatures exceed the safe operating threshold, the limit switch automatically breaks the electrical circuit to shut down the heat source, protecting your equipment from damage and ensuring safe operation. Once the unit cools to a safe temperature, the switch resets to allow for normal operation. Ideal for repair and maintenance of residential and commercial heating units, this bimetal disc control is a reliable replacement for maintaining efficient airflow and temperature regulation.
