DIVISION COMMUNICATION METHOD OF AN EXTENSION WIRE ASSEMBLY FOR A COMBINATION SWITCH FOR A VEHICLE TO TRANSMIT AND RECEIVE SIGNALS BETWEEN A LIGHT UNIT AND A WIPER UNIT USING LESS CORD WIRES

摘要

PURPOSE: A division communication method of an extension wire assembly for a combination switch for a vehicle is provided to improve the assembly efficiency of the combination switch by reducing the number of cords of the extension wire assembly which connects a light unit and a wiper unit.;CONSTITUTION: A division communication method of an extension wire assembly for a combination switch for a vehicle is as follows. Signals transmitted from a light unit(1) to a wiper unit(2) are classified into five groups with a voltage division scheme, where the first group includes passing and high beam signals, the second group includes head lamp off, head lamp low and auto light signals, the third group includes fog lamp or head lamp washer signals, the fourth group includes right/left turning signals and right/left change signals, and the fifth group includes tail light signals.;COPYRIGHT KIPO 2010
