Electrical switching unit with separable contacts

An electrical switching device with separable contacts, comprising a switching apparatus including:

• a fixed electrical contact and a mobile electrical contact that can be moved between a closing position and an opening position;
• a control lever mechanically coupled to the mobile electrical contact, the control lever being rotatable, about a first axis of rotation, between a first position and a second position, the movement of the control lever from the first position to the second position causing a movement of the mobile contact from the closing position to the opening position;
• an anti-rebound lever, that is mounted on the control lever by a pivoting link and can be rotated, thanks to the pivoting link, about a second axis of rotation parallel to the first axis of rotation, between a rest position and an opened-out position;
• wherein the anti-rebound lever is arranged so as to move from the rest position to the opened-out position when the control lever reaches the second position;
• and wherein the anti-rebound lever is arranged to engage a stop of the switching apparatus when the anti-rebound lever is in the opened-out position thereof and when the control lever is in the second position so as to prevent the control lever from leaving the second position.
