Abstract
Control panel including a cover mounted on a support that is provided with a tactile pressing detection zone in which a force sensor that includes a pressure-sensitive zone is arranged behind a detection zone between the cover and the support so as to produce an electrical control signal when a user applies a determined tactile pressing force to the detection zone. The tactile pressing force is transmitted axially (X1) towards the sensitive zone via a spacer made of elastically compressible material interposed between the sensor and the cover. The spacer includes at least one compressible portion that defines a transversal top surface that bears against the cover and a transversal bottom surface that bears against the sensitive zone of the sensor. The top surface has an area smaller than the area of the bottom surface.
