Herewith D.CD.1145 which is a modification to F.CD.1112 to improve the wiring and provide more clearance between the switch terminals and earth. The cables which are taken through a rubber grommet in the metal floorboard, are kept well clear of the clutch casing, and protected by an extension formed at the top of the cover plate. The switch base has been turned through 90º to assist the run of cables, but the centre of plunger remains as before. DA.{Bernard Day - Chassis Design} DCD. 1162 | ||
