Method for the initial adjustment of a control device for electronic equipment, having: - an upper actuating element having an upper actuating face, on which a user can exert at least one control action by applying a generally downwardly directed pressure to this upper face; - a lower supporting mounting, the upper actuating element being mounted so as to be movable relative to this mounting by a vertical movement between an upper rest position, towards which the upper actuating element is returned elastically, and an active lower position; - a switch which is actuated by the upper actuating element when the upper actuating element is in its active lower position; and - an articulated structure which is interposed vertically between the upper actuating element and the lower mounting to keep the upper actuating element parallel to a horizontal plane during its vertical downward movement relative to the frame, and which includes at least one shaft, characterized in that the method consists of the following successive steps: - a) applying, in the vertical direction, a preload having a predetermined value to said at least one shaft so as to take up the initial assembly play; - b) providing an adjustment stop (104, PC), fixed relative to the lower mounting and forming a stop surface which interacts with a facing portion of said at least one shaft associated with this stop, for positioning said at least one shaft relative to the lower mounting, this step b) of providing the adjustment stop consisting in: b1) positioning a stop member relative to the lower mounting in such a way that a front end of this stop member is in contact with said facing portion of said at least one shaft; and b2) immobilizing said stop member relative to the lower mounting; - c) removing said preload, while the stop member remains immobilized. - an upper actuating element having an upper actuating face, on which a user can exert at least one control action by applying a generally downwardly directed pressure to this upper face; - a lower supporting mounting, the upper actuating element being mounted so as to be movable relative to this mounting by a vertical movement between an upper rest position, towards which the upper actuating element is returned elastically, and an active lower position; - a switch which is actuated by the upper actuating element when the upper actuating element is in its active lower position; and - an articulated structure which is interposed vertically between the upper actuating element and the lower mounting to keep the upper actuating element parallel to a horizontal plane during its vertical downward movement relative to the frame, and which includes at least one shaft, characterized in that the method consists of the following successive steps: - a) applying, in the vertical direction, a preload having a predetermined value to said at least one shaft so as to take up the initial assembly play; - b) providing an adjustment stop (104, PC), fixed relative to the lower mounting and forming a stop surface which interacts with a facing portion of said at least one shaft associated with this stop, for positioning said at least one shaft relative to the lower mounting, this step b) of providing the adjustment stop consisting in: b1) positioning a stop member relative to the lower mounting in such a way that a front end of this stop member is in contact with said facing portion of said at least one shaft; and b2) immobilizing said stop member relative to the lower mounting; - c) removing said preload, while the stop member remains immobilized. - a) applying, in the vertical direction, a preload having a predetermined value to said at least one shaft so as to take up the initial assembly play; - b) providing an adjustment stop (104, PC), fixed relative to the lower mounting and forming a stop surface which interacts with a facing portion of said at least one shaft associated with this stop, for positioning said at least one shaft relative to the lower mounting, this step b) of providing the adjustment stop consisting in: b1) positioning a stop member relative to the lower mounting in such a way that a front end of this stop member is in contact with said facing portion of said at least one shaft; and b2) immobilizing said stop member relative to the lower mounting; - c) removing said preload, while the stop member remains immobilized.
