Claim 7:
8. Device for indicating the status of a gas burner when operated with a gas control apparatus with liquid-filled temperature controller comprising: a device connected to an outlet of the gas control apparatus for the gas burner comprises a housing which has at least two interconnected chambers, which are separated gas-tight by a membrane connected on one side to an electrically conductive component, wherein a chamber A is connected to the gas outlet of the gas control apparatus, the membrane to which the gas pressure of the gas burner is applied through an opening in the chamber A when the gas valve is open produces a stroke, wherein a chamber B in which the side of the membrane having the connected electrically conductive component is positioned closes a circuit via contact elements led outwards and suitably indicates the operating status, wherein when the gas valve is closed, the stroke of the membrane goes back to the starting position at its own spring constant, the circuit is opened and no operating status is indicated wherein alternatively external components can be switched by connecting a relay to the contact elements.
