Berko 4520-0015-000 Limit Switch ensuring a low-impedance path andThe Berko 4520 0015 000 Limit Switch is a critical safety component designed for precise thermal regulation in forced air heating systems and HVAC equipment. This 96 165F Auto Limit Switch monitors internal plenum temperatures, automatically breaking the electrical circuit if the temperature exceeds the 165F threshold to prevent heat exchanger damage or hazardous conditions. Once the system cools to the 96F reset point, the automatic reset
