Magnet armature, comprising - a first spring element with a first stiffness k1, - a second spring element with a second stiffness k2, - a bush between the first spring element and the second spring element, - a cylindrical section, wherein the cylindrical section has a first subsection with a first diameter, a second subsection with a second diameter and a step between the two subsections (ZA1, ZA2), - the step between the two subsections (ZA1, ZA2) constitutes a magnet armature stop, and - the magnet armature can move between an idle position, an end position and a central position between the idle position and the end position, wherein the idle position is that position in which the magnet armature is located when there is no magnetic force acting on it, characterized in that - the magnet armature stop constitutes a stop for the bush, - the bush touches the magnet armature stop during the movement from the idle position to the central position, and - the bush does not touch the magnet armature stop during the movement from the central position to the end position, - the second spring element is biased or the stiffness of the second spring element is considerably higher than that of the first spring element, so that: - the first spring element is elastically deformed during the movement from the idle position to the central position, but not during the movement from the central position to the end position, and - the second spring element is elastically deformed during the movement from the central position to the end position, but is not deformed or is deformed only to an insignificant extent during the movement from the idle position to the central position. - a first spring element with a first stiffness k1, - a second spring element with a second stiffness k2, - a bush between the first spring element and the second spring element, - a cylindrical section, wherein the cylindrical section has a first subsection with a first diameter, a second subsection with a second diameter and a step between the two subsections (ZA1, ZA2), - the step between the two subsections (ZA1, ZA2) constitutes a magnet armature stop, and - the magnet armature can move between an idle position, an end position and a central position between the idle position and the end position, wherein the idle position is that position in which the magnet armature is located when there is no magnetic force acting on it, characterized in that - the magnet armature stop constitutes a stop for the bush, - the bush touches the magnet armature stop during the movement from the idle position to the central position, and - the bush does not touch the magnet armature stop during the movement from the central position to the end position, - the second spring element is biased or the stiffness of the second spring element is considerably higher than that of the first spring element, so that: - the first spring element is elastically deformed during the movement from the idle position to the central position, but not during the movement from the central position to the end position, and - the second spring element is elastically deformed during the movement from the central position to the end position, but is not deformed or is deformed only to an insignificant extent during the movement from the idle position to the central position.
