Abstract:
A hybrid current switching device has a casing which includes a main current switch having first fixed and movable contacts connected in series with first and second terminals, a power switch device connected in parallel with the main current switch and switchable between an on-state and an off-state, a secondary current switch having second fixed and movable contacts and being connected in series with the power switch device, and a movable-contacts holding shaft on which the first and second movable contacts are mounted. The contacts-holding shaft is positioned inside the casing rotating around a rotation axis to move the movable contacts between a closed position where they are coupled with the corresponding fixed contacts and an open position where they are electrically separated therefrom. The first and second movable contacts are mounted on the rotating shaft with an angular offset relative to each other when in the open position.
