Abstract

An optical switching means including an optical fiber moving means which is moved by an electromagnetic force, a spring body which has a guide hole through which an optical fiber passes and at least one magnetic body. The magnetic body is fixed on one of its ends and one end is arranged so as to be almost parallel with the moving optical fiber. The moving optical fiber is connected with a fixed optical fiber by moving the magnetic body with an electromagnetic force, thereby effecting optical switching with low attenuation and high accuracy.
