A light diverting and switching device connected in cascade between a transparent cylindrical optical conductor at a light source side and another transparent cylindrical optical conductor at a light emission side for diverting and picking up a part of light transmitted through the optical conductor. The light diverting and switching device is constructed with a first transparent cylindrical member having one surface formed on a horizontal plane connected with the optical conductor at the light source side and another surface formed on an inclined plane, a second transparent cylindrical member having one surface formed on an inclined plane connected with the inclined surface of the first cylindrical member and another surface formed on a horizontal plane connected with the optical conductor at the light emission side and further provided with a circular hole elongated in a horizontal direction toward the inclined surface, a third transparent cylindrical member for adjusting the diverted light installed so as to move back and forth in the circular hole of the second cylindrical member and having an edge surface formed on an inclined plane the same as the inclined surface of the second cylindrical member, and a fourth transparent cylindrical member for receiving the diverted light connected with the first cylindrical member and having a connected surface opposed to the third cylindrical member.
