Before you order

  • Confirm the part number 573409113 against the appliance's own documentation or data plate before ordering.
  • Check that an air proving switch, rather than another pressure switch type, is the component required for the fault being investigated.
  • Verify the existing switch's connections and mounting arrangement against the replacement before fitting.
