Abstract: A switching apparatus for medium voltage electric systems, said switching apparatus comprising one or more electric poles, wherein, for each electric pole, said switching apparatus comprises:
- a first pole terminal, a second pole terminal and a ground terminal, said first pole terminal being electrically couplable with a first conductor of an electric line, said second pole terminal being electrically couplable to a second conductor of said electric line and said ground terminal being electrically couplable to a grounding conductor;
- a first contact arrangement including a first fixed contact member and a first movable contact member, said first fixed contact member being electrically connected to said first pole terminal and including a first fixed contact, said first movable contact member being electrically connected to said second pole terminal and including a first movable contact, said first movable contact member being reversibly movable along a translation axis, so that said first movable contact can be coupled with or decoupled from said first fixed contact;
- a second contact arrangement including a second fixed contact member and a second movable contact member, said second fixed contact member being electrically connected to said ground terminal and including a second fixed contact, said second movable contact member being electrically connected to said second pole terminal and including a second movable contact, said second movable contact member being reversibly movable about a corresponding rotation axis, so that said second movable contact can be coupled to or decoupled from said second fixed contact;
- an actuation assembly for actuating the first and second movable contact members of each electric pole during a switching manoeuvre of said switching apparatus, said actuation assembly including an actuation shaft reversibly movable about a corresponding rotation axis;
- a motion transmission assembly for transmitting mechanical forces provided by said actuation shaft to the first and second movable contact members of each electric pole.

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

Abstract: Method for manufacturing a switching apparatus for electric systems, comprising the following steps:
- providing a first housing shell (3) of said switching apparatus, said first housing shell being of thermoplastic material and including a first coupling edge (4) for coupling with another housing shell, said first coupling edge having a first coupling surface and first ribs protruding from said first coupling surface and extending along said first coupling edge;
- providing a second housing shell (5) of said switching apparatus, said second housing shell being of thermoplastic material and including a second coupling edge (6) for coupling with said first housing shell, said second coupling edge having a second coupling surface and second ribs protruding from said second coupling surface and extending along said second coupling edge;
- assembling said first and second housing shells and a number of operating components of said switching apparatus, thereby obtaining a preliminary assembly (99) of said switching apparatus;
- joining the first and second coupling edges of said first and second housing shells through a vibration welding process, thereby forming a junction between said first and second housing shells and obtaining a sealed outer casing for said switching apparatus.
