Icp Heil-Quaker 602950 Limits Switch 150-40 SA

The Icp Heil-Quaker 602950 Limit Switch is a temperature-actuated control unit designed to monitor internal heat conditions and regulate circuit response. It operates with a 150F open and 40F close range, allowing controlled switching based on temperature changes. This component is commonly applied in furnaces and other HVAC systems where thermal safety regulation is required during heating operation. Positioned near the sensing zone, it detects temperature variations and supports controlled system cycling for stable performance during normal operating conditions.
