Ensure the safety and efficiency of your heating system with this professional-grade 7-inch high limit control switch. Designed as a critical safety feature for residential and commercial furnaces, this thermal limit switch monitors heat exchanger temperatures to prevent overheating. When the internal temperature reaches its safety threshold, the switch automatically interrupts the heating cycle, protecting your HVAC equipment from damage and reducing fire risks. This component is essential for forced air systems and gas furnaces that require a reliable thermal cutout with a 7-inch insertion depth for accurate airflow temperature sensing.
