Abstract
A magnetic actuating device (1) for a current switching device (2) comprises: —a ferromagnetic stator (3) and a ferromagnetic armature (4) which is movable between a first end position (5), which is close to the ferromagnetic stator (3), and a second end position (6) which is spaced apart from the ferromagnetic stator (3), —a compression spring (7)configured for urging the ferromagnetic armature (4) to the second end position (6), —an electrical coil (8) energizable for electromagnetically attracting the ferromagnetic armature (4) to the first end position (5), and —a mechanical locking assembly (10) configured for releasably blocking the ferromagnetic armature (4) in the first end position (5).
