Abstract:
1. A switching device which comprises: a switching unit comprising an external case that houses one or more electric poles, said switching unit comprising, for each of said electric poles, a first disconnection contact, a second disconnection contact and one or more solid state switches, which can be switched between an on-state and an off-state, and vice versa; a supporting frame comprising, for each of said electric poles, a third disconnection contact and a fourth disconnection contact, wherein said switching unit is movable, with respect to said supporting frame, between an insertion position (A) where said first disconnection contact and said second disconnection contact are coupled with the corresponding third disconnection contact and fourth disconnection contact, respectively, and a withdrawn position (B) where said first disconnection contact and said second disconnection contact are separated from the corresponding third disconnection contact and fourth disconnection contact, respectively, and vice versa; actuating means for moving said switching unit between said insertion position (A) and said withdrawn position (B), and vice versa; a control unit, which is configured to control the operation of said switching unit and said actuating means, said control unit comprising control means that are configured to coordinate the operation of said actuating means and said solid state switches, when an insertion/withdrawn operation of said switching unit has to be performed, so that said actuating means move said switching unit only when said solid state switches are in an off-state.
