Hybrid switch including a mechanical switch (2), at least a first static switch (9) placed on a first branch (R1) parallel with the contacts (2a, 2b) of the mechanical switch (2) and a backup charge (15), in particular a capacitor, placed on a second branch (R2) parallel with the contacts (2a, 2b) of the mechanical switch (2) and couplable with/decouplable from the mechanical switch (2) by means of a second static switch (16). An electronic control unit (35) executes at least one control cycle of the first static switch (9) and of the second static switch (16) to extinguish the arc that forms between the contacts (2a, 2b) subsequent to under load opening of the mechanical switch (2).
