ABSTRACT:
An optical switch includes at least one optical fiber exit terminal disposed in a plane, at least first and second optical fiber entrance terminals disposed in the plane, and a movable reflector disposed in the plane and angularly movable about a point in the plane for reflecting and/or refracting a light ray from the optical fiber exit terminal selectively into one of the first and second optical fiber entrance terminals for thereby optically coupling the optical fiber exit terminal and said one optical fiber entrance terminal. When the optical fiber exit terminal and the optical fiber entrance terminal are optically coupled to each other, the movable reflector is held against a stopper while it is being subjected to a certain torque, so that the movable reflector is stably stopped.
