R.R. 199 (250T) (S.D.676 19-7-17) MP 180865 X.4583. EFC Mr Brock X.4583. BY2-P27.4.23. 40/50 CHASSIS. STEERING COLUMN. RE STEERING COLUMN SWITCH. The present switches at the bottom of the Steering Column are made up as mouldings with a rubber base material - they are expensive to make and have a very poor appearance when finished. Mr Brock has therefore prepared a similar unit using Mouldensite in place of the rubber base (Vulcanite) material. The only point which I think is likely to arise in connection with this is, whether Mouldensite is likely to track by the Mouldensite itself being transferred on to the brass and preventing contact being made, or, on the other hand the brass rubbing a thin film on to the Mouldensite which would allow leakage to occur. We think you ought to put this switch on to a column and make and break it for days together so as to have a large number of make and breaks in the shortest possible time. We are anxious to adopt this material if it is satisfactory. BY.{R.W. Bailey - Chief Engineer} By | ||
