Sterling HVAC 11J11R02682 High Limit Switch

The Sterling HVAC 11J11R02682 High Limit Switch is a temperature-responsive control component used to monitor operating temperatures within compatible unit heaters and related equipment. It reacts when a specified temperature threshold is reached, causing a change in the connected electrical circuit. Positioned near heat-producing sections of the unit, it works with control assemblies to provide temperature-based input during operation. In HVAC systems, this switch assists with temperature regulation by responding to changing thermal conditions and communicating those changes through the connected control circuit to influence equipment operation.
