PURPOSE: A coupling structure of an elevator switch is provided to prevent different colored light emitted from a first light emitting cell and a second light emitting cell from being mixed each other by a coupling structure of an internal frame. CONSTITUTION: A coupling structure of an elevator includes an outer frame(300), a circuit board, and an inner frame(500). The outer frame comprises a guide ring(200) and a press plate(100). A tact switch and a light emitting diode are integrated on the circuit board. The light emitting diode comprises multiple first light emitting cells(940a) arranged in the edge of the circuit board and multiple second light emitting cell(940b) arranged in the center part of the circuit board. The inner frame is arranged separately from the inner periphery of the outer frame in predetermined interval and the light of the first light emitting cell is emitted to the guide ring by the inner frame. A projection part is formed in one side of the inner frame and a through-hole in which the second light emitting cell is inserted is formed in the projection part to emit the light of the second light emitting cell to the press plate.
