Carrier HH680366 Limit Switch

The Carrier HH680366 is a little switch in HVAC systems. This limit switch is so small but it is preventing possible equipment damage. A limit switch doesn’t work like traditional on/off switches, it switches automatically when an electrical circuit is interrupted by certain conditions. The HH680366 may be triggered by high pressure, low pressure, or high temperature in HVAC systems. In this case, our switch opens the circuit, which cuts the compressor or other equipment off to avoid malfunctions that might demand it and result in safety hazards. The HH680366 limit switch acts as a silent guardian protecting your Carrier HVAC system and your home’s comfort.
