Abstract: An elastomeric keypad (1) is shown having at least one key (3) having an elastomeric dome (41) defining a chamber (42) and provided inside with an activating means (43), an activation means (44) cooperating with the activating means (43), and at least one compensating channel (48) opening at the chamber (42) to enable for a flow of fluid from the chamber (42), while the elastomeric dome (41) collapses, and to the chamber (42), while the elastomeric dome (41) releases. In order to suppress the sound intensity of the push up event, at least one of the compensating channels (48) includes at least one valve arrangement (5) generating fluid restrictions while the fluid returns to the chamber (42). Preferably the valve arrangement (5) has a form of a Tesla Valve.

Abstract: A motor vehicle control panel includes a front face including a control zone; a printed circuit board; at least one electrically conductive capacitive detection element extending along a vertical axis from the rear surface of the front face to an electrical contact zone of the printed circuit board; a light source mounted on the printed circuit board and able to produce a back lighting light beam toward the control zone through the capacitive detection element; the capacitive detection element also comprises at least one rigid tubular part forming a light guide for the light beam and at least one elastic part made in one piece with the rigid tubular part so as to compensate the clearances between the rear surface and the detection element and between the printed circuit board and the detection element.
