Abstract
403,059. Indicators for switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Electricitats-Ges.; 2, Friedrich Karl-Ufer, Berlin.) March 7, 1932, No. 6859. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 7, 1932]. [Class 38 (v).] An indicator for indicating the position of a two-position device, such as an electric switch, comprises translucent strips 6, 7 of complementary colours, viz. red and green, one or other of which is illuminated according to the position of the device by groups of lamps 4, 5 of corresponding colours. When one or other of the groups of lamps is illuminated the corresponding strip appears bright while the strip of complementary colour remains dull. The indicator may be incorporated in a mimic circuit diagram 1 comprising translucent strips 2 illuminated by lamps 3. The diagram 1 may be formed of glass, artificial resin or a material known under the registered trade mark "Cellon" coate with a non-translucent colour at parts not required for indications. The symbols 6, 7 may be coloured by coloured paper strips.
