Abstract

PURPOSE:To make possible high density packaging of the photo switch and enable the same to be driven with small electric power by focusing light from the optical fibers which are parallel disposed in close contact, allowing the same enter a movable reflecting mirror through a convex lens and controlling the inclination of the movable reflecting mirror. CONSTITUTION:Light from optical fibers 1 passes through focusing type optical elements 2 and convex lens 3 and is projected to a movable reflecting mirror 4, the reflected light whereof again passes through the convex lens 3 and focusing type optical elements 2 and is entered to the optical fibers. It is possible to selectively let the exit light from the optical fibers 1 enter the other optical fibers 1 by changing the inclination of the movable reflecting mirror 4 by the external control signal, thus the photo switch may be constituted.
