Icp Heil-Quaker 602950 Limits Switch 150-40 SA

The Icp Heil-Quaker 602950 Limits Switch 150-40 SA monitors temperature and changes the electrical circuit when the sensing condition reaches its designated switching point. Its thermal switching mechanism responds to temperature changes by altering contact position, allowing the connected safety or control circuit to regulate equipment operation. The switch is positioned at the specified temperature-sensing position and connects to compatible furnace wiring according to the equipment circuit design in HVAC systems. Temperature-responsive switching maintains controlled operation of connected heating components, supports thermal circuit protection, and provides consistent electrical response during changing operating conditions.
