A multi-functional remote control switch on a steering wheel includes a housing installed at the steering wheel. A printed circuit board is secured in the housing and formed with a plurality of manipulation switches and switch circuits. A dial is rotatably installed between the housing and printed circuit board. A switching device outputs a manipulation signal of the manipulation switches to a system selected by turning the dial. This switch manipulates various systems of the vehicle by using one remote control switch mounted on the steering wheel, thereby reducing the cost of materials and obtaining a sufficient installment space.
