Abstract
A reversing linear solenoid polarized in a permanent magnetic manner having a first and second end stroke position as well as at least one armature, wherein it has a spring system or is operated at such a spring system which exerts a force in the direction of the center stroke position on the armature or armatures in the end stroke position(s). The spring system and the reversing linear solenoid are coordinated with one another such that the armature or armatures are held in a permanent magnetic manner against the spring force in both end stroke positions. The spring system is configured such that the potential energy (elastically) stored by movement of the armature or armatures into its/their end stroke movements is of equal magnitude. If external restoring forces caused by the application are present, they must be taken into account in the design of the spring system.
