触发开关技术领域本发明涉及一种触发器开关，其具有用于操作自行车电路的杠杆或旋转手柄开关中的上紧，保持和释放机构。 该开关由一个带集成车把夹的外壳和一个Aufzieh，保持，释放和显示机构组成。 Aufzieh-，保持和释放过程齿段所需的每个啮合Aufzieh-，保持和棘爪被安置在单个盘状部件中。 在这种情况下，优选具有内齿的锯齿段布置在盘元件的开口中的圆周内。 Aufziehbewegung通过一个细长的Aufziehklinke从执行元件通过位于光盘元件Aufziehzahnsegment内的支撑板传输。 当前的档位通过弹性显示带传送，该弹性显示带在驾驶员的视野中沿着车把夹从那里围绕车把绕过电缆卷筒的齿。 为了改善显示识别，显示带的透明盖形成为透镜或放大镜。 开关机构由开关外壳和塑料覆盖元件封闭。 在这个包覆元素也是Schaltzugspannung调节螺丝的记录。

The invention relates to a trigger switch with a wind-up, holding and release mechanism with lever or twist grip shifters for operating bicycle circuits. The switch comprises a housing with an integrated handlebar clamp and a wind-up, hold, release and display mechanism. Required for the wind-up, holding and releasing operation toothed segments, in each of which a wind-up, holding and locking pawl engages, are housed in a single disc-shaped member. Here is a toothed segment, preferably arranged with internal gearing, within the scope in an opening of the disk element. The priming movement is transmitted via a slender wind-up pawl from the actuator through the support plate through to point to another within the disk element Aufziehzahnsegment. The current gear position is transmitted via an elastic display band which meshes in a toothing of the cable reel, from there to the handlebars around, along the handlebar clamp in the view of the driver. To improve the screen recognition the transparent cover of the indicator strip is designed as a lens or magnifying glass. The switch mechanism is enclosed by the switch housing and a covering element made of plastic. There is also the inclusion of the adjustment for the rear derailleur At this lining element.
