Abstract
A multiple signal transmitting apparatus for automobiles includes a plurality of switches mounted on the steering wheel of an automobile, a multiplexing circuit mounted on the steering wheel for multiplexing the output signals of the switches, at least one light-emitting device mounted on a moving part rotatable together with the steering wheel so as to be arranged on a circumference lying in a plane perpendicular to the central axis of rotation of the steering wheel and concentric with the central axis of rotation to generate a light signal in response to the multiplexed output signal of the multiplexing circuit, at least one light-sensitive device mounted on the surface of the steering wheel bearing portion facing the light-emitting device to receive the light signal from the light-emitting device and generate an output signal, and a decoder circuit mounted on the body portion of the automobile to decode the output signal of the light-sensitive device to generate signals corresponding to the output signals of the switches.
