ABSTRACT:
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.
