PURPOSE: A multfunction switch is provided to easily perform an assembly process by simplifying a structure of a light emitting part and a light receiving part on a PCB surface in a switch. CONSTITUTION: A body(10) includes an opened upper end portion and a vertical groove formed in a central portion. A lower PCB switch assembly(20) is inserted within the vertical groove on the body. The lower PCB switch assembly includes a through-hole formed in the central portion. A spacer(30) having the through-hole formed in the central portion is arranged on an upper portion of the lower PCB switch assembly. A top PCB(40) having the through-hole formed in the central portion is arranged on the upper portion of the spacer. An elastic board(50) having the through-hole formed in the central portion is arranged on the upper portion of the top PCB. A ring shaped loop(60) having the through-hole formed in the central portion is arranged surrounding the elastic board on the upper portion. A stick assembly(70) is arranged on the upper portion of the ring shaped loop. A combining projection for interconnecting a peripheral part of the stick assembly is formed on a reflector wheel(80). A cover(90) has the through-hole passing through the upper portion of the stick assembly.
