一种电视调谐器具有壳体和安装在壳体上的旋转频道选择轴。有多个独立的支撑构件通过所述轴的平行平坦区域定位并安装在其上，所述平坦区域的大小不同，以确保支撑构件的正确放置。单个线圈带，每个携带一个调谐螺钉，固定到轴组件。用于控制螺钉调整的简化抓紧装置利用线圈弹簧提供用于将小齿轮移动到与调谐螺钉的操作接合处的初始力。调节螺钉由弹性臂保持，该弹性臂使螺钉的头部偏向轴，从而牢固地保持螺钉在任何调整位置。每个线圈带都具有从一侧向外延伸的触点，并定位为与固定在印刷电路板上的悬臂弹簧成员进行电气和机械接触，而印刷电路板又由外壳保持。
A TV tuner has a housing and a rotating channel selector shaft mounted on the housing. There are a plurality of individual support members positioned by and mounted on parallel flatted areas of the shaft, which flatted areas vary in size to assure correct placement of the support members. Individual coil strips, each carrying a tuning screw, are fixed to the shaft assembly. A simplified clutching arrangement for controlling adjustment of the screws utilizes a coil spring to provide the initial force for moving a pinion gear into operating engagement with the tuning screws. The tuning screws are held by resilient arms which bias the head of the screws toward the shaft to thus firmly maintain the screws in any adjusted position. Each of the coil strips have contacts extending outwardly from one side and positioned to be in electrical and mechanical contact with cantilever spring members fastened to a printed circuit board which in turn is held by the housing.
