Abstract

1520596 Switch for light SIEMENS AG 12 July 1976 [14 July 1975] 28972/76 Heading G2J Two optic fibres 2 are arranged so that they can be aligned to convey light across the junction between the fibres, or as shown to interrupt transmission. As shown the fibres are in a sealed enclosure 1 and are operated magnetically like a reed switch and for this purpose magnetic sleeves 3 are provided.
