Abstract (en)

It is a load-break or short-circuit current switch (1) comprising a main circuit (2) for the circulation of electric current and a secondary circuit (3) for the circulation of shunt electric current. The main circuit (2) comprises a switch-disconnector (4) with a fixed contact (5) and a moving contact (6), while the secondary circuit (3) comprises a vacuum switch (7) that is actuated by the moving contact (6) of the switch - disconnector (4), so that the load-break or short-circuit current switch (1) of the invention can execute at least three operating positions, making - breaking - disconnecting - grounding.
