Carrier HH680502 Limit Switch 320734-701 you know that safeguarding aThe Carrier HH680502 Limit Switch is a critical safety component designed for precise thermal monitoring in residential and commercial furnaces. This 90 120F auto reset limit switch functions as a primary high limit control, specifically engineered to open the electrical circuit if internal plenum temperatures exceed the 120F threshold. Once the heat exchanger cools to the 90F reset point, the switch automatically closes, restoring system operation.
