ABSTRACT:
An earthing switch for a medium voltage switchgear comprising a plurality of fixed contacts, a plurality of movable contact surfaces which are suitable to contact said plurality of fixed contacts and a support structure suitable to support moving means which allow the movement of said second plurality of contact surfaces. The earthing switch comprises at least one guide which comprises a fixed element and a moving element coaxially coupled therewith, said moving element being operatively connected to said movable contact surfaces so as to allow their movement along a substantially rectilinear direction from a first position, corresponding to an open condition of said switch, to a second position corresponding to a closed condition of said switch.
