MAGNETIC TRIGGER MECHANISM

A magnetic trigger mechanism with a yoke with armature opening. The armature is coaxially surrounded by a coil having an excitation coil, which is acted on by a force of a preloaded spring and which remains in a first end position due to magnetic holding force of a permanent magnet when there is no current flowing through the excitation coil. The permanent magnet is arranged at a first end of the armature and the second end position of the armature being achieved by a brief flow of current through the excitation coil together with the accompanying lowering of the magnetic holding force and the spring force. The first end of the armature is guided in the coil body, and the second end position, which faces the armature opening, is guided by a centering ring, the highly permeable centering ring rests against the yoke at the armature opening and can move.
