Herewith is D.CD.126 Revised Horn Switch for use in connection with F.CD.103 Modified Steering Column Controls. The assembly and manufacture of the components have been simplified, and one or two difficulties, such as the rivetting of the contact blade in the inner casing and the small horizontal retaining screws, have been eliminated. A rubber stop has been provided to eliminate the noise on release. Would RHC{R. H. Coverley - Production Engineer}/CAN. give an idea of the cost saving before we proceed to detail.
