Bard HVAC 8406-042BX Pressure Switch Els PW 17895 whereas Section VIII valves areThe Bard 8406 042BX Pressure Switch is the direct engineering update for the legacy 8406 042, specifically designed for precise differential pressure sensing in Bard wall mount units. Calibrated for a 0. 28" PF pressure set point, this normally open air pressure switch monitors blower operation and heat pump airflow to prevent coil icing or compressor damage. For technicians diagnosing HVAC pressure switch failure, this component ensures the system
