    • An improved electrical commutator which is particularly useful in a vehicle steering wheel system, includes sets of wire brushes or fingers on a first plate. The wire brushes or fingers contact plural co-planal rings on a second plate. The two plates rotate relative to each other. The wire brushes or fingers decrease the likelihood that any one of the sets will have a short circuit. Should any one of the wires bend, break, or come out of contact with its associated contact ring, there is a likelihood that at least several of the other wires will remain in contact. In addition, there are plural sets of wire brushes or fingers associated with each of the contact rings, again increasing the likehood that the circuit will remain intact. In other features, the plural sets may be mounted such that circumferentially spaced ones of the sets face opposed directions. In this way, there is no difference in the resistance to rotation, or the quality of the electrical communication, when the wheel is turned either clockwise or counter-clockwise.
    • 在车辆方向盘系统中特别有用的改进的电换向器在第一板上包括多组线刷或手指。 线刷或手指接触第二板上的多个共平面环。 这两个板相对于彼此旋转。 钢丝刷或手指减少了其中任何一组发生短路的可能性。 如果任何一根导线弯曲,断裂或脱离与其相关的接触环的接触,则至少有几根导线可能会保持接触。 另外,与每个接触环相关联的有多组线刷或手指,这又增加了电路保持完好的相似性。 在其他特征中,多组可以被安装成使得这些组中的周向间隔的组面向相反的方向。 这样,当车轮顺时针或逆时针转动时,转动阻力或电通信质量没有差别。
