    • The invention relates to a magnetic trigger mechanism at least comprising a yoke having an armature opening, in which yoke an armature is placed, which armature is coaxially surrounded by at least one section of the coil body having at least one excitation coil and which is acted on by the force of a preloaded spring element and which remains in a first end position due to the magnetic retaining force of a permanent magnet when current is not flowing through the excitation coil, the permanent magnet being arranged in the area of the first end of the armature together with a base extending between the armature and the permanent magnet, and the second end position of the armature being achieved by means of a brief flow of current through the excitation coil together with the accompanying lowering of the magnetic retaining force and the spring force, which is effective then. The invention is characterized in that the first end of the armature, which first end faces away from the armature opening, is guided in the coil body in a centered manner, and the second of the armature, which second end faces the armature opening, is likewise guided in a centered manner by means of a centering ring centered in the coil body, the highly permeable centering ring lies against the yoke at the armature opening and can move radially relative to the yoke, the base is centered in the coil body, the centering ring together with the coil body ensuring that the armature lies flat in the area of the first end without tipping and always guaranteeing maximum retaining forces due to the armature lying flat, the spring element having a larger diameter than the armature, and the magnetic flux commutating upon triggering from a series connection to a parallel connection.
    • 磁性触发机构本发明涉及一种至少包括具有电枢开口的磁轭的磁性触发机构,在该磁轭中放置电枢,该电枢由至少一个具有至少一个励磁线圈的线圈体的至少一个部分同轴环绕, 通过预加载的弹簧元件的力而被接通,并且当电流不流过励磁线圈时,由于永磁体的磁保持力而保持在第一端部位置,永磁体布置在第一端部区域中 衔铁与在衔铁和永久磁铁之间延伸的底座一起,衔铁的第二端位置通过短暂的电流流过激励线圈以及伴随的磁保持力的下降和弹簧 力量,这是有效的。 本发明的特征在于,衔铁的第一端部远离衔铁开口的第一端部以中心方式在线圈体中被引导,并且衔铁的第二端部面对衔铁开口的第二端部 同样借助以线圈体为中心的定心环以中心的方式引导,高度可渗透的对中环在衔铁开口处靠在轭上并且可相对于轭作径向运动,基体在线圈体中居中, 定心环与线圈体一起确保电枢在第一端的区域中平坦地平放而不倾斜并且始终保证由于电枢平放而产生的最大保持力,弹簧元件具有比电枢更大的直径,并且磁通量 在从串联连接触发并联时进行换向。
