An optical switch includes at least one input end, at least one output end, a reflective device and a switching device. The reflective device includes at least one flat glass and at least one reflective element provided on the flat glass. The switching device changes the position where the at least one ray enters the reflective device. The at least one output end selectively output the at least one ray after the at least one reflective element reflects it. Alternatively, a plurality of reflective elements are provided. The reflective elements are disposed in the reflective device such that the reflective device has a plurality of reflective regions. When the switching device switches the rays to enter different reflective regions, the rays can be output from different output ends.
