Structure of electric circuit for instrument panel of automobile and method for forming the same

摘要

A flexible flat conductor wiring board 5 having required electric circuits is affixedly disposed on an instrument cluster 2 of an instrument panel portion of an automobile so as to be connected to switches and instruments 3A to 3E that are provided on the instrument cluster 2 in groups so that an electric circuit is formed. Electric functioning components needed to carry out electric control of the switches and instruments are dispersedly provided on the end portions of centrally arranged switches and instruments or provided on the wiring board 5 with the electric control functions being incorporated in the electric circuits of the instrument cluster 2. Switches and instruments 3A to 3E are provided, and electric circuits for the switches and instruments 3A to 3E are provided so as to make the instrument cluster 2 an independent electric component. The instrument cluster 2 as an independent electric component is mounted on the instrument panel portion 1 of an automobile.
