Abstract
392,381. Secret contact-combination switches. DANN, H. C., The Laurels, Ruskington, Lincolnshire, and PALLOT, A. C., Aultone, Barrow Hedges Way, Carshalton Beeches, Surrey. July 14, 1932, No. 19921. [Class 38 (v).] A secret contact - combination switch comprises a series of insulating discs A loosely mounted on a spindle B. Each disc has a contact H passing through it so that when the discs are all in their correct positions, as shown by symbols on the edges of the discs, circuit is made between the fixed contacts J. A further disc C is slidably mounted on a squared part of the spindle and can be moved by a disc D screw-threaded on the spindle to clamp the pile of discs together to make good contact. The symbols may be marked on separate rings which are keyed on to the discs so that the combination may be changed at will.
