Abstract (en)

A switching device (3)comprising an electric conductor (10), a breaker (6) connected to said conductor (10), and a switch (7), said switch (7) comprising a switch element (9,16) that is pivotable around a rotational axis to a first position in which a first end (13) thereof is electrically connected to the breaker (6) and a second end (14) thereof is electrically connected to the electric conductor (10), and to a second position in which said second end (14) thereof is disconnected from the conductor (10) and connected to a grounded element (12), wherein the switch element (9,16) is also movable to a third position in which it is disconnected from the conductor (10) and from the grounded element (12). The third position is a position in which the dielectric strength between the switch element (9,16) and the conductor (10) and grounded element (12) is higher than in any of the pivotation positions of the switch element (9,16) between the first and second position obtained solely by pivotation of said switch element (9,16).
