    • A switch apparatus for use in a vehicle in which the DC signal path electrically connecting between the horn switch disposed on the steering wheel in the steering apparatus and the horn disposed on the vehicle body is utilized to transmit, for example, a constant-speed running control signal from a signal transmitting unit disposed in the steering apparatus to a signal receiving unit disposed in the vehicle body. The signal transmitting unit includes a plurality of switches provided for the purpose of constant-speed running control, and a signal frequency generated in response to manipulation of a selected one of these switches is superposed on the DC signal which is supplied by way of the DC signal path to energize the horn. The DC signal path is also utilized to supply required power to the signal transmitting unit in the steering apparatus.
    • 一种用于车辆中的开关装置,其中电连接设置在转向装置中的方向盘上的喇叭开关和设置在车体上的喇叭之间的直流信号路径被用于例如传输例如恒速行驶 控制信号从设置在转向装置中的信号发送单元传送到设置在车体中的信号接收单元。 信号发送单元包括为了进行恒速运行控制而设置的多个开关,并且响应于这些开关中选择的一个开关的操作而产生的信号频率叠加在通过DC供给的DC信号上 信号通路来激励喇叭。 DC信号路径也用于向转向装置中的信号发送单元提供所需的电力。
