Abstract
582,741. Indicators for switches. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BURNS, G. A. April 27, 1944, No. 7854. [Class 38 (v)] An indicating-board of the mimic-line diagram type including portions such as 16 which are rotatable and represent switches, and portions such as 28 which serve as luminous indicators, is made of a number of detachable units 10 all presenting a smooth front surface, flush with the front surface of the board. Contacts 17, 18 mounted behind the panel remotely control the apparatus represented by a switch unit 16, and are operated by a cam 18 when a portion 16 is pushed in against spring pressure, and rotated. An indicating-lamp 25 mounted behind the panel and shining through the material, is used to indicate when the position of the apparatus controlled does not correspond to the position of the indicator 16. Each unit except the switch unit is provided with a circular extension 12 which protrudes through the panel and is secured at the back by a spring clip 14 which engages a groove in the extension and is used as a fixing for the indicating lamp assembly.
