<p>PURPOSE:To reduce the cost by decreasing number of harness sets with respect to kinds of operation switches. CONSTITUTION:Resistors 26, 28 whose resistance differs from each other are connected in series with plural operation switches 12, 13, 14 and connected in parallel, a switch device 15 and an electric device 16 are connected by a single harness 34 and an input voltage V2 to a control means 20 is varied when each of the operation switches 12,13,14 is closed to control the content of operation of the electric device 16 thereby reducing number of harness 34.</p> |
