The button includes a body (12) with a button-pusher (14) slidingly mounted in it, between a recessed position, when the button is pressed and a protruding position when it is at rest. There is an arrangement for vibrating the pusher when it is pressed by the user. A portion of the pusher is made of a ferromagnetic material, and a winding (46) of a conductor wire is fixed on the body of the button, along which a portion of the pusher passes. This winding is fed by an alternating current produced by an electric oscillator (48) which is controlled by a control unit (50) of the lift when the pusher is pressed. On the body of the button, is fixed a permanent magnet (52) oriented in the pusher axis to attract and repel the pusher when the current flows through the winding.
