<p>The invention proposes an arrangement which comprises a reinforcement (18), an electrical switch (42) with tactile effect, a force transmission member (50) which cooperates with the electrical switch with tactile effect (42), a permanent magnet (72) which acts on a magnetic disc (62) linked to the force transmission member (50) to slow down the displacements of the force transmission member; and an electromagnet (72) with controlled electrical power supply and which, when powered, produces a magnetic field which cancels the magnetic field of the permanent magnet (72).</p> |
