Description
The Carrier HK06MC012 Pressure Switch 0.65″ WC is a furnace safety control component to monitor negative air levels within the venting and combustion systems during equipment operation. It operates by detecting changes created by the inducer motor and activates or interrupts the electrical circuit based on calibrated conditions. Commonly applied in gas, packaged heating units, and forced-air HVAC systems, the switch is connected to the inducer assembly and vent tubing to verify proper airflow before ignition begins. Its role within the system supports pressure verification and controlled startup sequencing during heating operation.
