Abstract

PURPOSE:To make the moving distance of movable parts small and obtain a switch which is fast in changing-over speed and has no restriction in operatable mode by providing optical guides of which end faces approach to each of two sets of three-dimensionally intersecting optical guides by way of a three-dimensional point of intersection in-between. CONSTITUTION:An optical guide 63 of which the end part 64 provided with a tapered part 68 exists near an optical guide 61 and the other end part 66 provided with a similar tapered part 69 exists near an optical guide 62 is installed by way of the point of intersection of the optical guides 61, 62 which three-dimensionally intersect without mutually intersecting. When the movable part is moved by a small distance, the end part 64 and the end part 65 of the guide 61 and the end part 66 and the end part 67 of the guide 62 attach and detach respectively. When both end parts are held connected, the incident light from the end part 65 etc. is transmitted to the guide 62 via the end part 64, the guide 63, the end part 66 according to the sections of the guides 61-63. In addition, the quantity of the light changed over is controlled according to the refractive indexes of the guides 61-63 and since the moving distance of the movable parts is small, the changing-over speed is fast. Since it is not of directional coupling type, the photoswitch having no restriction in operation mode is obtained.
