Abstract:
    The aim of the invention is to prevent or at least to reduce disturbance signals on the output of the voltage supply circuit (S), appearing when switching off a voltage supply circuit (S), in particular a data signal device (DG) ascertaining to a household device, which can be connected to additional data signal devices by means of a data network, on a cut-off signal. The output voltage thereof is reduced initially to a determined minimum level, such that when a greater requirement of the outlet flow of the flow/voltage supply device (I, U), which can be controlled by a voltage output circuit (S), is signalled, the cut-off signal appears and said device produces an output voltage and an outlet flow corresponding to determined output. The output voltage is reduced to the determined minimum level and it is then switched off.
