PURPOSE: A door/window switching apparatus using an optical sensor is provided to open and shut a door and a window without an additional external transmitter by generating an internal optical signal and inputting a secret number. CONSTITUTION: A door/window switching apparatus is used for opening or shutting a door and a window by using signals of an optical signal generator(10) and an optical signal receiver(20). The door/window switching apparatus includes a system controller(30), a non-volatile memory(33), an optical signal converter(21), an operation controller(40), and a driver(50). The system controller is used for inputting a secret number into the non-volatile memory. The optical signal converter is used for converting a received optical signal to a number. The door and the window are opened and shut by the operation controller and the driver.
