An optical switch includes a reflective element that may be moved into and out of the path of an input light beam without rotation about a hinge. The switch includes a right angle prism whose hypotenuse is an angularly-fixed reflective surface. The prism is fixed to a base platform that is pivotal about an underlying pivot member. A switchable electromechanical relay is energizable for selectively rotating the platform about the pivot member to move the prism in and out of the path of the input beam. A collimator fixed to the output face of the prism assures proper registration of the output with a beam when reflected.
