    • The invention concerns a steering-column switch with a buffer spring which permits rotational contact between contacts rigidly mounted on the housing (2) of the steering-column switch and contacts on the rotatably mounted steering wheel. The aim of the invention is to simplify the mounting for the buffer spring. This is achieved by virtue of the act that an open recess for the buffer spring is cast on the switch housing, the recess being closed off by a cover which is mounted to rotate with respect to the housing. The buffer spring is thus integrated into the switch housing in such a way that a special spring housing is unnecessary. Preferred embodiments of the invention relate to an additional locking element which locks the cover so that it cannot rotate with respect to the switch housing when the switch is mounted. The locking element also ensures that the cover cannot be rotated with respect to the switch casing until the steering wheel has been mounted in place on the steering-wheel columns
    • 本发明涉及一种转向柱开关用的螺旋弹簧,其提供到冲程开关的壳体(2)壳体固定连接之间的可旋转的接触,并且连接到可旋转地安装车轮。 本发明的目的是简化为时钟弹簧接收器。 这在一个开放的锅开关外壳,它是由一个可转动地安装相对于所述壳体盖闭合上模制完成。 因此,卷绕弹簧被集成在开关壳体可以与使得一个单独的弹簧壳体被分配。 涉及一个附加的锁定构件,其相对于所述盖到所述开关壳体以旋转固定在开关的存储状态锁定有利的进一步发展。 所述锁定构件还使得有可能的是,盖仅仅通过相对于所述开关壳体转向柱在方向盘上的组件是可旋转的。
