An electrical apparatus having at least one parametrizable function and which includes at least one potentiometer having an actuation member, cooperating with notched indexation devices demarcating several discrete positions of the actuation member. Each discrete position corresponds to a desired value of a parameter. An analogue/digital conversion and interpretation circuit receives an analogue voltage delivered by the potentiometer, dependent on the discrete position taken by the actuation member, and delivers a digital signal representative of the position of the actuation member and hence of the desired value of the parameter.
