Abstract

PURPOSE:To obtain a thin optical switch by providing a light shield body which is put between optical fibers and cuts off a light signal directly to an operating piece which has elasticity. CONSTITUTION:The optical switch 1 consists of, for example, the plate type operating piece 2 made of an elastic body such as rubber and the light shield body 3 projected from its reverse surface. When the operation piece 2 of the optical switch 1 arranged on an operation board G is pressed down by applying downward force, the light shield body 3 on the reverse surface moves into the gap between optical fibers F and F to cut off the light signal transmitted between the optical fibers F and F. When the operating piece 2 is released from the force, the operating piece 2 restores itself with the restoring force of its own elasticity and the light shield body 3 exits from the gap between the optical fibers F and F, so that the light signal travels between the optical fibers F and F.
