The light projecting means 1 provided to penetrate the elastic body 9 at an angle projects an optical signal, and only when no pressure is applied to the elastic body 9, The provided light receiving means 3 receives the reflected light signal from the reflecting surface 11, but does not receive the reflected light signal when the elastic body 9 is deformed under pressure.

A smooth reflective surface 1 inclined at a predetermined angle with respect to the inner wall surface between the inner wall surfaces.
1 is formed on the inner surface of the elastic body 9 itself by metal vapor deposition or the like, and a light projecting means 1 and a light receiving means 3 are provided through the other two walls 9c and 9d, respectively.

An optical fiber or the like is provided passing through the wall portion 9d at a position where it receives a reflected light signal from the reflecting surface 11 only when the elastic body 9 is not deformed.

As shown in the figure, the optical signal projected from the light projecting means 1 is reflected by the reflecting surface 11 and received by the light receiving means 3, and is in an on state. In order to control the optical signal in this state, for example, as shown in FIG. 2, when pressure is applied from the outside to the wall 9a of the elastic body 9, the elastic body 9 is elastically deformed and the inclination angle of the reflective surface 11 is changed. As a result, the light receiving means 3 is no longer able to receive the reflected light signal, and the light receiving signal at the light receiving means 3 is turned off.
When the pressure on the elastic body 9 is removed, the elastic body 9 is restored to the state shown in FIG. 1, and the reflected light signal can be received by the light receiving means 3 again.

なるような使用の仕方もできる。 In the above-mentioned optical switch, as shown in FIG. 2, the inclination angle of the reflecting surface 11 is usually changed by applying pressure to the elastic body 9. Leave it as the state,
When the pressure on the elastic body 9 is removed in order to control the optical signal in this state, the elastic body 9 becomes the state shown in FIG. 1, and the reflected light signal can be received by the light receiving means 3. It can also be used in such a way that the light reception signal is turned on.

The number of parts required can be reduced, and a light projecting means is provided by penetrating the elastic body at a position where the optical signal is projected at an angle inclined to the reflecting surface, and pressure is applied to the elastic body. By providing a light-receiving means through the elastic body at a position that receives the reflected light signal from the reflection surface only when the reflection surface is not in the state, the inclination angle of the reflection surface can be changed by elastic deformation of the elastic body, Since the reflected light signal to the light receiving means is controlled on and off, it has the remarkable effect of being able to be made smaller and manufactured at lower cost than conventional optical switches.
