Abstract

927,957. Switch cases. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 10, 1962 [March 27, 1961], No. 11072/61. Class 38 (5). A switch contact assembly is provided with at least one moulded lens 2 arranged to facilitate contact inspection. The lenses are moulded integrally with a transparent plastics casing 1, e.g. of a small relay. Alternatively, they may be formed as part of a buffer block, &c., forming part of the contact assembly. The lenses may be spherical or cylindrical.
