Abstract: A direct driving type optical switch is proposed. A row of V-grooves is formed on a base and a plurality of output optical fibers is arranged on one side of the base and respectively placed in the V-grooves. A movable input optical fiber is placed on another side of the base and atop a selected V-groove. The movable input optical fiber is pressed by a positioning block 446 and clamped tightly into the selected V-groove, whereby the input optical fiber is aligned with the output optical fiber in the selected V-groove for signal transmission.
