| 6137 Rm{William Robotham - Chief Engineer}/Wst.7/AP. 12th April 1937 The Motor Roof Lamp Co., 609 Lordship Lane, Wood Green, LONDON N.22. Dear Sirs, With reference to the push-pull switches which you supply for use on our chassis, it has been found that the knobs on the same have a tendency to work loose, and we should like to know if you have any propositions to offer to prevent this. When the knobs work loose the plunger inevitably falls back in the switch and it is then necessary to remove the whole switch from the instrument board for repair. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
