The invention relates to an actuator (7) which comprises: a frame (11) intended for being in contact with the tactile interface via a contact wall (13) so as to transmit haptic feedback to the tactile surface; a stator (15) connected to the frame (11); a movable core (19) connected via at least one resilient element to the frame (11) and intended for being moved by the stator (15) so as to generate the haptic feedback; an electromagnet (17) and at least one permanent magnet (20), one of which is supported by the stator and the other by the movable core (19). The actuator (7) also comprises a shock absorber (23) arranged between the movable core (19) and the contact wall (13), and said resilient element is sized so that, when the electromagnet is not powered, the movable core (19) applies a bearing force towards the contact wall (13) and, when the electromagnet is powered according to a predetermined polarisation, the movable core (19) moves away from the contact wall (13).
