Abstract: An actuation unit for a switching apparatus is provided. The actuation unit includes a rotating contact shaft coupled to the movable contacts of the switching apparatus and first mechanical actuation means coupled to the contact shaft and configured to actuate the contact shaft during a closing maneuver of the switching apparatus. The first mechanical actuation means include a spring assembly, a first lever member coupled to the spring assembly and a plurality of second lever members coupling the first lever member to the contact shaft. The first mechanical actuation means include a rotating cam assembly including one or more cam members couplable to the first lever member of the first mechanical actuation means. The actuating unit includes a brake member for reducing the rotational speed of the cam assembly, when the cam assembly is rotating towards a rest position, during a closing maneuver of the switching apparatus.
