| 摘要 |
The invention relates to a contactor/disjunctor type switch device having at least an energy commutation pole comprising fixed contacts (1, 2) which cooperate with movable contacts (5) coupled to an actuating member (15) actuated by a solenoid (8) or by a fastening lever (12) linked to a subjection (23), characterized in that fastening lever (12) actuates movable contacts actuating member (15) directly and in that solenoid movable parts (10) actuate actuating member (15) through a coupling lever (13) adapted to be coupled to movable parts (10) by a demountable coupling (19, 21) associated with fastening element (14) conditioned by fastening state.
