1. A device, including:
- an assembly comprising;
an upper panel having an upper face, anda locating subsystem configured to locate a point of contact of a pointing element on the upper face of the upper panel;
a supporting frame; and
a detecting subsystem configured to detect a control action, the control action comprising applying, by means of the pointing element, an amount of pressure greater than a threshold value to the upper panel, independently of a location of a point of contact on the upper face of the upper panel,wherein the detecting subsystem comprises a disengageable stop for the assembly configured to move between a high rest position and one or more low positions in response to the control action,wherein movement of the disengageable stop produces a mechanical impulse of a vertical principal orientation on the upper panel while the disengageable stop allows the assembly to move generally downward relative to the supporting frame in response to the control action,wherein the mechanical impulse is transmitted to the pointing element to generate a tactile sensation in response to the control action, andwherein a part of a peripheral edge of the assembly is configured to be in upward abutment against the supporting frame in response to the control action and when the point of contact of the pointing element is offset horizontally relative to the disengageable stop.

Abstract
The invention proposes a touch-sensitive faceplate (18) comprising:
- a horizontal upper panel (32);
- means (34) for locating the point (P) of contact of a pointing element (30) on the upper face (32s) of the upper panel (32); and
- means for detecting at least one control action, independently of the location of the point of contact (P) on the upper face (32s) of the upper panel (32),
- characterized in that it comprises means (48, 52) for producing a mechanical impulse of a vertical principal orientation on the upper panel (32), when the value of the pressure (F2) is greater than or equal to the threshold value and that is transmitted to the pointing element (30) to generate a tactile sensation in response to the control action.
