1. An electric household appliance comprising a low-voltage capacitive power supply connected to an electrical power network and designed to generate a low-voltage, wherein said low-voltage capacitive power supply comprise a capacitive dividing circuit comprising a first and second input terminal connected to a first and second power line at a first and second predetermined potential respectively;

  • a first output terminal adapted to generate said low-voltage enabling signal;

    first and second charge-accumulating means connected between said first and second input terminal; and

    at least one voltage limiter connected parallel to said second charge-accumulating means and designed to switch from a nonconducting to a conducting state when subjected to a voltage above a predetermined breakdown voltage;

    said first and second charge-accumulating means being so designed that the voltage at the terminals of said second charge-accumulating means his below said predetermined breakdown voltage.
