ABSTRACT:
An electromechanical locking mechanism which can execute a pulse-control for the locking or unlocking of door panels. A bistable electromagnet interacts with an appropriately shaped lever so that a permanent magnet which is fastened to the lever arm and a permanent magnet which is fastened to a mounting plate repel one another and can thereby move the lever into a secure position, namely into a locked or unlocked position.
