| 摘要 |
The invention concerns an electrical appliance with at least one parameterable function, comprising at least a potentiometer (3) with an actuating member (4) co-operating with indexing means (52, 53) with notches representing physically several discrete positions (511 to 51n) of the actuating member (4), each position corresponding to a desired value of a parameter. Analog-to-digital converting and interpretation means (6) receive an analog voltage (Ve) delivered by the potentiometer (3) and deliver a digital signal representing the position of the actuating member and therefore the desired value for the parameter.
