    • Rotary electronic component of the invention has a contact board and an elastic contact. The contact board, including an annular contact having an arc-segmental portion split by a slit with a predetermined width and signaling contacts disposed at spaced positions and in electrical continuation with the arc-segmental portion, is fixed in a resin molding with the annular contact exposed on the top plane of the resin molding. The elastic contact slides on the contact board along the annular contact. In this rotary electronic component, a stress occurring when the annular contact is fixed by molding on to the contact board is relaxed owing to presence of the slit. Thus, a rotary electronic component generating an electric signal with a stabilized waveform over a long time can be obtained.
    • 本发明的旋转电子部件具有接触板和弹性接触。 接触板包括具有由具有预定宽度的狭缝分割的弧形部分的环形接触件,并且设置在间隔开位置并且与电弧段部分电连续的信号触点在环形接触件中固定在树脂模制件中 暴露在树脂成型的顶面上。 弹性接触件沿着环形接触件在接触板上滑动。 在这种旋转电子部件中,由于存在狭缝,所以通过模制在接触板上将环形接触件固定时产生的应力被放宽。 因此,可以获得长时间产生具有稳定波形的电信号的旋转电子部件。
