Description
The Emerson Climate-White Rodgers 3L09-26 Limit Switch Open is a temperature response switching used to monitor heat levels within heating equipment assemblies. It features a 1.87-inch configuration and operates by opening the circuit at 180F and reconnecting at 160F as temperatures decline. It is commonly applied in furnaces, air handlers, and unit heaters where thermal monitoring near heat-generating sections is required in HVAC systems. The switch is positioned within the appliance structure close to heat exchangers, coordinating electrical activity based on internal temperature changes during normal heating cycles.
