Abstract
A control panel comprising a cover that is equipped with at least one zone for detecting tactile contact forming a control button, in which a force sensor comprising a pressure-sensitive zone is arranged between the cover and the support so as to detect actuation of the control button, the force of the tactile contact being transmitted axially to the sensitive zone via a spacer plate made of an elastically compressible material that is inserted between the sensor and the cap, characterized in that the internal surface of the cap comprises a series of protruding elements that are distributed over the internal surface of the cap opposite the sensitive zone so as to form a number of regularly distributed zones of localized overpressure.
