ABSTRACT:
The member comprises: a support structure presenting a control zone, said control zone having a through hole; a non-conductive elastic covering covering a control face of the control zone, at least in register with the through hole; and a touch-sensitive detector at least partially in register with the through hole and mounted on or in the vicinity of the face of the control zone that is opposite from its control face; the elastic covering having a rest position in which the finger of an operator contacting the free surface of the elastic covering lies outside the touch detection space of the detector, and a deformed position in which the finger of the operator in contact with the free surface of the elastic covering lies within the touch detection space of the detector. According to the invention, in the rest position, the elastic covering is spaced apart from the touch-sensitive detector, and in the deformed position, the elastic covering is in contact with the touch-sensitive detector.
