    • A relay includes a leaf spring for bearing an armature at a free end of a yoke, the leaf spring forming, first, a bearing plate lying against the yoke and, second, a pull-back spring applied thereto in one piece. The pull-back spring has a first section cut free from the middle of the bearing plate so that the bearing plate is subdivided into two plate sections on which the armature rests only at its lateral regions on its bearing edges. Further, the pulled-back spring as its free end cut arcuately roughly symmetrical to the center axis of the bearing plate to exert an approximately symmetrical pull-back force on the armature.

    • The relay has a base (1) with stationary mating contact elements (11, 12, 13, 14), a coil (5), a permanent magnet (4) and also a rocker armature (3) which is arranged between the coil and the base, is connected to movable contact elements (21, 22, 23, 24) and is mounted on the base by means of bearing strips, the bearing strips simultaneously serving as electrical connections for the movable contact elements. The bearing strips (25, 26) are secured to the bearing supports (15, 16), which are designed as connection elements, of the base in planes extending at right angles to the basic plane of the base. As a result, the contact separation can be set with low tolerance even during production, and it is not dependent on tolerances of the individual parts. This structure consequently permits non-problematic, cost-effective production of the individual parts and accurate assembly without the requirement of subsequent adjustment.

    • A relay includes a spool, or coil (3 and 4), and a yoke (5) next to the spool. In front of the spool, an armature (8) that activates a contact spring (16) is accomodated in a contact space positioned upstream in one of the free sides of the armature. The contact spring has an initial leg (16a) extending straight across the overall width of the relay and a U-shaped second leg (16b) mounted on the first. The free end of the U-shaped spring leg (16b) operates in conjunction with two reciprocal-contact elements (13 and 14). The generally Y shape results in a contact spring (16) with a maximum possible free length and hence a low spring constant, meaning a low relay-response output, while retaining the prescribed compact design.
    • 继电器包括线轴或线圈(3和4)以及靠近线轴的轭(5)。 在线轴的前面,启动接触弹簧(16)的电枢(8)容纳在位于电枢的一个自由侧上游的接触空间中。 接触弹簧具有直线延伸穿过继电器的整个宽度的初始支脚(16a)和安装在第一支架上的U形第二支脚(16b)。 U形弹簧腿(16b)的自由端与两个往复接触元件(13和14)一起工作。 通常Y形状导致接触弹簧(16)具有最大可能的自由长度,因此具有低弹簧常数,意味着低的继电器响应输出,同时保持规定的紧凑设计。
