Abstract (en)
A switching device for low voltage electrical circuits comprising at least one pole having an arc chute (50, 51, 100), a stationary contact (2, 6) and a corresponding moving contact (3, 7) that can be operated by a contact shaft (4) in such a manner as to move between a first position in which it is engaged with the stationary contact (2, 6) and a second position in which it is spatially distanced from the stationary contact (2, 6). The switching device comprises at least one moving device, operatively connected to and operated by said contact shaft (4) in such a manner that at least one element of the moving device moves towards the space that is created between the moving contact (3, 7) and the stationary contact (2, 6) when the moving contact (4) moves from the first position thereof towards second position thereof.
