Abstract:
A control device for a household electrical appliance comprising:an interface configured to enable a user to set or modify parameters of one or more operational members of the appliance by a command and control circuit in communication with the appliance, the interface comprises one or more selectors arranged to enable setting or modifying of the parameters of the appliance, the selectors being connected to a resonant electrical circuit arranged to generate or to respond to a radio-frequency signal in a modifiable manner representative of the setting or modification effected by the user, wherein the resonant electrical circuit comprises a plurality of capacitors of mutually different capacitance values, selectively connectable to an inductor cooperating with an induction element associated with the command and control circuit and fixed to the household electrical appliance, the radio-frequency signal being sensed by the induction element which enables the command and control circuit to set or modify in the appropriate manner the parameters of the operational members for controlled operation of the household electrical appliance.
