A switching apparatus including one or more electric poles. For each electric pole, the switching apparatus includes a first pole terminal, a second pole terminal, and a ground terminal. The switching apparatus further includes a plurality of fixed contacts spaced apart one from another, a movable contact, which is reversibly movable about a corresponding rotation axis according to opposite first and second rotation directions, so that said movable contact can be coupled to or uncoupled from one or more of the above-mentioned fixed contacts, a vacuum interrupter including a vacuum chamber, in which a fixed arc contact and a movable arc contact are enclosed and can be coupled or separated, and a motion transmission mechanism operatively coupled to the movable arc contact of said vacuum interrupter.
