What it is

The Hamworthy 573409116 is an air proving switch used to monitor airflow within an appliance's combustion air circuit. It provides a proving signal to the appliance control so that the burner is only allowed to fire when air movement is detected. Where proving is lost, the switch signals the control to shut the appliance down.

Before you order

  • Confirm the part number on the existing switch matches 573409116
  • Check the appliance's installation and service documentation to confirm this switch is the correct component for the model
  • Air proving switches sit within the combustion air circuit, so fitting should be carried out by a competent heating engineer
