Abstract

1520813 Optical switch STANDARD TELEPHONES & CABLES Ltd 11 Nov 1976 [18 Nov 1975] 47427/75 Heading G2J A flexible light-conductive body is arranged to be flexed from one curvature to another of reverse curvature. On opposite sides of the body are arranged respectively light-reflecting and lightabsorbing regions and depending on which is on the outside of the curve, the light is reflected for onward transmission in the body, or is absorbed.
