Bard 9043-311 - SPST Pressure Switch 0.52 in WC

Bard part 9043-311 is an OEM SPST air pressure switch used to prove proper airflow or draft in Bard wall-mounted HVAC equipment before the unit is allowed to run. This switch is commonly tied into the safety/control circuit so the system can confirm the correct pressure signal is present and help prevent nuisance shutdowns or unsafe operation when airflow is restricted. The factory setting is 0.52 inch water column, so matching the correct rating is critical for proper cycling and reliable operation. If you are replacing this switch due to intermittent trips or failure to close, verify the tubing, ports, and venting/airflow path are clear and confirm your unit model and serial before ordering to ensure the correct Bard OEM fit.
