An optical switch comprising one input optical fiber, two output optical fibers, a stationary mirror for reflecting a light beam from the input optical fiber to cause it to enter into one output optical fiber, a movable mirror moving into and out of an optical path of a light beam from the input optical fiber, and a means for driving the movable mirror; whereby when the driving means drives the second mirror to a position at which it interrupts the optical path, a light beam from the input optical fiber is reflected by the movable mirror so that it enters into the other output optical fiber.
