White-Rodgers 3L09-5 Limit Switch dry flange surfacesThe White Rodgers 3L09 5 is a professional grade board mount limit control engineered for precision temperature monitoring in forced air heating applications. This 1 2" bimetal disc limit switch features a 3. 12" insertion length, making it a critical safety component for high limit sensing within the heat exchanger airflow. As an open on rise switch action device, it is factory calibrated to break the electrical circuit at a fixed 160F and
