摘要
The present invention relates to an operating mechanism (1) for M.V. earthing switch comprising an operating disk (10) rotating about a main axis (100), a connecting assembly (11) which connects operatively said operating disk (10) to said earthing switch. The operating mechanism (1) also comprises an operating lever (12) for rotating said disk (10) from a first angular position to a second angular position according to a closing movement (Wl) and from second angular position to said first angular position according to an opening movement (W2). According to the invention the operating mechanism (1) comprises an interlock assembly (15) that prevents a re-closing movement of said disk (10) when, starting from said second angular position and according to said opening movement, said disk (10) reaches a pre-established angle (α).
