Abstract

A hybrid current switching device comprises two terminals for electrical connection with an associated electrical circuit and a casing containing: - a main current switch (MS) comprising a first fixed contact and a corresponding first movable contact which are connected in series with and positioned between the two terminals; - a power switch device (PES) which is connected in parallel with the main current switch and can be switched between an on-state and an off-state; - a secondary current switch (IS) having a second fixed contact and a second movable contact, the secondary current switch being connected in series at least with the power switch device; - a movable-contacts holding shaft (4) on which the first and second movable contacts are mounted. The contacts-holding shaft is positioned inside the casing rotating around a rotation axis so as 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 there from; the first and second movable contacts are mounted on the rotating shaft with an angular offset relative to each other when being in the open position.
