Abstract:
Electrical apparatus having at least one parametrizable function, comprising at least one potentiometer having an actuation member, able to take positions, each position corresponding to a desired value of a parameter, means of analogue/digital conversion and interpretation receiving an analogue voltage delivered by the potentiometer, dependent on the position taken by the actuation member and delivering a digital signal representative of the position of the actuation member and hence of the desired value of the parameter, this digital signal serving as parametrization control signal for the apparatus, wherein the positions of the actuating member are discrete positions, the actuation member cooperating with notched indexation means, these notched indexation means demarcating these discrete positions such that a restoring force compels the actuation member to stabilize in one of the discrete positions without resting between two discrete positions.
