<p>The present invention concerns an electrical apparatus (1) comprising: a base (2); at least one first connection terminal (3); at least one fixed contact (4) that is fixed relative to the base (2) and electrically connected to said first connection terminal (3); at least one second connection terminal (5); at least one mobile contact (6) that is movable relative to the base (2); a conductive blade (7) carrying said mobile contact (6) and electrically linked to said second connection terminal (5); an elastic element (8) for biasing said blade (7) towards one or the other of two stable states, respectively a conduction state in which said mobile contact (6) is applied against said fixed contact (4) and an insulation state in which said mobile contact (6) is separated from said fixed contact (4); and a manoeuvring member (9) that is movable relative to the base (2) and arranged to drive the blade (7); the electrical apparatus (1) being characterised in that the blade (7) comprises a drive tab (10) arranged to drive a yoke (11), said yoke (11) engaging with a receptacle portion (12) of the base (2), together forming a mechanical link having a translational and/or rotational degree of freedom; in that a viscous fluid (13) is provided between the yoke (11) and the receptacle portion (12) of the base (2); such that the shear stress of the viscous fluid (13) brakes the movement of the yoke (11) relative to the base (2).</p> |
