ABSTRACT:
A steering wheel switching circuit is provided which is capable of controlling component parts on a car body side through the use of a small quantity of coupling devices in cooperation with a controlling part by connecting a switching part installed on the steering wheel and two sets of series circuits installed on the car body part in parallel with a power supply. The switching portion includes a switch circuit having diodes electrically short-circuited across two terminals in both the positive and the negative direction. These two sets of series circuits have load resistances and switching elements with control terminals with the controlling part applying opposite polarity signals to the control terminals of the switching elements.
