The water switch has a functional component (8) in which is arranged a Venturi nozzle (5) for water volumetric measuring in the water passage between the water inlet (3) and outlet (4). A membrane (17) connected to the functional component separates an upper chamber (28) from a lower chamber (29) which is connected to the water passage. The static pressure in the Venturi nozzle is connected to the upper chamber via a connecting drilling (18) and the membrane is connected to a connecting rod (27) for operating the gas valve (22). |
