Abstract:
1. A hybrid current switching device comprising: a casing having protruding outside thereof a first terminal and a second terminal configured for input and output electrical connection with an associated electrical circuit, respectively, wherein the hybrid current switching device comprises, positioned inside the casing: a main current switch including a first fixed contact and a corresponding first movable contact, the first fixed and movable contacts being connected in series with and positioned between the first and second terminals; a power electronics switch configured to be connected in parallel with the main current switch and to be switched between an on-state and an off state; a secondary current switch having a second fixed contact and a corresponding second movable contact, the secondary current switch being connected in series with the power electronics switch; and a movable-contacts holding shaft on which the first movable contact and the second movable contact are mounted, the movable-contacts holding shaft being positioned inside the casing rotating around a rotation axis so as to move the first and second movable contacts between a closed position in which the first and second movable contacts are coupled with the first and second fixed contacts, respectively, and an open position in which the first and second movable contacts are electrically separated from the first and second fixed contacts, wherein the first and second movable contacts are mounted on the movable-contacts holding shaft with an angular offset relative to each other when in the open position.
