Abstract
A switching apparatus includes one or more electric pole units, each electric pole unit comprising a fixed contact, a movable contact, a first pole terminal, a second pole terminal, and a motion transmission arrangement to reversibly move the movable contact. The motion transmission arrangement includes a conductive motion transmission member coupled to the movable contact. The first pole terminal is in electrical connection to the fixed contact while the second pole terminal includes a first coupling region in electrical connection with a second coupling region of the conductive motion transmission member. Each electric pole unit further includes a shielding element formed by a conductive hollow body and arranged in a relative fixed position with respect to the second pole terminal and the motion transmission member. The shielding element is arranged to at least partially surround the first coupling and the second coupling region.
