Bard part number 8406-075 is an OEM pressure switch set to open on a falling pressure signal at 0.65 inches water column, with a tolerance of plus or minus 0.05 inches. This switch is used as a safety and verification device in Bard wall-mount HVAC equipment to confirm proper airflow or draft conditions before allowing the unit to continue operating, helping protect key components and prevent nuisance lockouts caused by incorrect pressure sensing.
