An electrical switching apparatus with separable contacts, comprising a switching device with: a fixed electrical contact and a movable electrical contact that can move between a closed position and an open position; a control lever mechanically coupled to the movable electrical contact, the control lever being rotatable, about a first axis of rotation, between a first position and a second position, movement of the control lever from the first position to the second position causing movement of the movable contact from the closed position to the open position; an anti-rebound lever, which is mounted on the control lever by means of a pivot connection and which is rotatable by means of the pivot connection about a second axis of rotation parallel to the first axis of rotation between a rest position and a deployed position; the anti-rebound lever being arranged to move from the rest position to the extended position when the control lever reaches the second position; the anti-rebound lever being arranged to mate with a stop of the switching device when the anti-rebound lever is in its extended position and the operating lever is in the second position to prevent the operating lever from leaving the second position; the control lever having a first arm on which is formed the pivot connection with the anti-rebound lever and a second arm on which is formed a further pivot connection with a connecting piece connected to the movable contact to ensure coupling between the control lever and the movable contact, the first arm and the second arm being perpendicular to the first axis of rotation and being integral with a control shaft of the apparatus extending along the first axis of rotation; the first arm and the second arm being connected by a rounded portion in the form of a circular arc centred on the axis of rotation; in the folded rest position, the anti-rebound lever overlapping the rounded portion and the upper edge of the anti-rebound lever being aligned with the outer edge of the rounded portion, so that the anti-rebound lever does not protrude from the rounded portion, so as not to hinder the movement of the control lever and the control shaft; characterised in that the centre of gravity of the anti-rebound lever is displaced relative to the pivot link towards the outside of the control lever with respect to the path followed by the pivot link when the control lever moves to its second position from the first position; and in that the centre of gravity is aligned with a first straight line passing through the first axis of rotation and being perpendicular to a second straight line coplanar with and passing through the pivot connection, the centre of gravity being offset towards the outside of the control lever with respect to the second straight line. a fixed electrical contact and a movable electrical contact that can move between a closed position and an open position;
