| 56139. Ha/Wat./YMA. 13th September, 1935. Messrs.Rotax, Ltd., Aviation Dept., Willesden Junction, London, N.W.10. Push Button Switches for Electric Starters. Dear Sir, With reference to the type N5CD button switch which you have supplied we still feel that although the button is recessed it is necessary to provide a small swivel cap over the button to prevent accidental operation in the aeroplane. We should prefer you to do this on switches you supply to us and we shall be glad if you will look into the matter as soon as possible and submit the altered drawing for our approval. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
