    Presentation of the invention
    In order to overcome the aforementioned problems, in accordance with the invention, the light-emitting diode and the pressure sensor are printed on the support film.
    Thus, the light-emitting diode can be positioned relative to the pressure sensor during the printing operation on the support film, which allows reliable relative positioning and easy industrialization. In addition, the printing operation produces thin flat layers of consistent hardness reducing the risk that when pressure is exerted on the aspect face of the control panel the light-emitting diode and the pressure sensor will deteriorate.

    According to another characteristic according to the invention, preferably the pressure sensor and the light-emitting diode are superimposed on each other on the support film.
    The pressure sensor and the light-emitting diode are thus made on the same side of the support film.
    According to an alternative characteristic according to the invention, preferably the pressure sensor and the light-emitting diode are arranged on opposite sides of the support film, the light-emitting diode is arranged between the pressure sensor and the decorative layer, and the support film is flexible.
    Thus, the printing of the pressure sensor and the light-emitting diode do not interfere with each other while being easily positioned satisfactorily with respect to each other. The light emitted by the light-emitting diode is not impeded by the pressure sensor. The deformation of the support film allows the pressure sensor to effectively detect the pressure exerted on the aspect face.
