Nordyne 626410R Limit Switch 115°F-155°F

The Nordyne 626410R Limit Switch is a temperature-actuated electrical control component. It is fitted in furnace assemblies and air handling equipment where it monitors internal temperature conditions and opens or closes the circuit between 115F and 155F depending on thermal variation. It is used in heating equipment control sections to supervise airflow-related temperature levels and signal the control board during abnormal or regulated temperature changes. Within HVAC systems, the switch relies on a sensing element that reacts to heat expansion, enabling circuit interruption or restoration to support controlled equipment operation.
