A multi-function switch contact structure for an automobile is provided to reduce weight by decreasing sizes of a movable plate and a fixing plate and to reduce cost without using grease and gold plating. A multi-function switch contact structure includes a movable plate(30), a fixing plate(40), and a photocoupler(50) for movable and fixing contact groups. The movable plate is installed at one end of a lever(10). The fixing plate is installed to face the movable plate. The photocoupler installs one LED(Light Emitting Diode)(51) on the movable plate and nine transistors(52) on the fixing plate. Each of the transistors is composed of first to third contact groups(53,54,55) which are installed at regular intervals.
