Switching apparatus for electric systems

A switching apparatus for electric systems, said switching apparatus having one or more electric pole units, each electric pole unit comprising:

• a fixed contact and a movable contact, said movable contact being reversibly movable between a first operating position, at which said movable contact is separated from said fixed contact, and a second operating position, at which said movable contact is coupled to said fixed contact;
• a motion transmission arrangement adapted to transmit mechanical forces to move reversibly said movable contact between said first and second operating positions, said motion transmission arrangement including a conductive motion transmission member coupled to said movable contact;
• a first pole terminal for coupling with a corresponding first line conductor, said first pole terminal being in electrical connection to said fixed contact;
• and
• a second pole terminal for coupling with a corresponding second line conductor, said second pole terminal being in electrical connection with said conductive motion transmission member,
• wherein each electric pole unit comprises a shielding element formed by a conductive hollow body, said shielding element being arranged in a fixed position with respect to said second pole terminal and said conductive motion transmission member, said shielding element surrounding, at least partially, a first coupling region of said second pole terminal and a second coupling region of said conductive motion transmission member in electrical connection with said first coupling region, such that said first and second coupling regions are located in an internal volume of said shielding element, and
• wherein said first coupling region of said second pole terminal and said second coupling region of said conductive motion transmission member are electrically connected to one another by one or more flexible conductors, said shielding element surrounding, at least partially, said one or more flexible conductors, such that said one or more flexible conductors are located in the internal volume of said shielding element.
