Abstract : An electro-mechanically actuated light switch is provided for transferring light energy into or out of a fiber optic light transmission path. Liquid material contained within the switch provides a continuity between two fiber optic light transmission path. The liquid material is chosen to have an index of refraction higher than the material which contains it, so that substantially total internal reflection is sustained along the optical axis of the fiber optic light transmission path. A transparent member is movably mounted in a port in the switch and resiliently supported for extension into the liquid material.
