<p>The device comprises a radiofrequency transmitter (9), at least one radiofrequency receiver (5A, 5B), and a control circuit (6, 7) connected to the receiver (5A, 5B) and controlling the functional elements (eg. resistive) of a household electrical appliance such as, by way of non-limiting example, for food cooking. The antenna (4A, 4B) of the receiver (5A, 5B) is positioned in an area in which the user's fingers can influence the receiver characteristics. When the user touches this area the signal received by the receiver (5A, 5B) changes amplitude, this change being used by the control circuit (6, 7) to control the appliance functional elements (3). Preferably two receivers (5A, 5B) are provided, of which one is used to increase the state of the functional element (for example to increase its heating power if the functional element is a resistance heater or the like), and the other is used to reduce the state of this element, in addition to eliminating noise. <IMAGE></p> |
