Abstract

PURPOSE:To improve the explosion proofing characteristics, insulation and reliability of an optical thermoswitch, by mechanically controlling a connection between optical fibers provided on substrates differing in terminal expansion when turning on and off an optical signal according to fluctuations of temperature. CONSTITUTION:An optical thermoswitch 1 is constituted by arranged supporting bodies 3 and 4, mde of materials, such as polyethylene and quarts glass, differing in coefficient of thermal expansion bonded in series on a base 2 made of, for example, ceramic. On the supporting bodides 3 and 4, optical fibers 5 and 6 transmitting an optical signal by becoming equal in level when the ambient temperature reaches a prescribed value are opposed to each other with a difference in level and fitted by being bonded together. At the other end of the fiber 5, a light emitting element 7 is arranged and at the other end of the fiber 5, a photodetecting element 8 is arranged. The switch 1 having the said constitution is operated when light from the element 7 is detected by the elemnt 8 because of optical axis alignment with the optical fibers 5 and 6 equal in level owing to the thermal expansion of the supporting bodies 3 and 4 depending upon the ambient temperature.
