| 摘要 |
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). |
