Abstract
An inexpensive and efficient switching device for use with optical fibers is disclosed wherein at least three optical fibers are mounted in the switching device with one of the at least three fibers mounted in a fixed magnetic block and the at least two fibers are mounted or fixed to a sliding nonmagnetic block. The blocks are held relative to a fixed base to which the fixed block is secured by means of permanent magnets and the switch is actuated by means of an electromagnet. Stops are provided for the sliding block to insure accurate alignment of the fibers to be switched during switch actuation and transmission of information in the fibers.
