1. A detection device for sensing user given control commands in terms of activation on a cover plate with the finger by a single touch, or by a force on the cover plate or along the plane of the cover plate, where said detection device is connected via capacitance to digital converter means to a micro-processor where said device is characterised by:

  • Said cover plate having a plane in a XY plane and a thickness along a Z-axis, substantially perpendicular to said XY planea first member being the cover plate being made from a conductive material, the cover plate has a certain ability to be depressed along the Z-axis upon activation from a finger; and

    the first member being configured to act as one electrode of a capacitor; and

    a second member being made from a conductive material and configured to act as the other electrode of a capacitor; and

    where the first member is electrically isolated from the second member; and

    the first member and the second member is assembled in a manner so the assembly constitutes an electrical capacitor having as electrodes, the first and the second members; and

    where the second member is divided into 3 or more sensing pads, each sensing pad detecting separate inputs.
