| matters, and the inspection lamp socket might also be included in this ammeter mounting. The press button for the Dashboard light should be very conveniently situated relative to the driver's hand, therefore with the ignition switch. On our cars, it is now the right hand, where these should be, rather than near the ammeter which would probably be near the centre of the car. Regarding the Bosch switch, mechanically and electrically this does not seem to be a very good piece of mechanism. The case also appears too big with two much face, and although the finish is nicely carried out, we do not think it would keep in very good condition owing to the extensive plain surface. We assume that while we are using the double wiring we shall want a distributing board on the lines of the R.R., but we think it would be quite a good move to substitute the Delco buzzer for the fuses. This would make the distributing board somewhat less complicated, although it would not be any smaller, as the buzzer would take up about as much room as the fuses. Judging from this, if the Delco switchbox is adopted, and the Delco buzzer, it looks as though the Delco should also make the distributing board. I do not think, however, it is a very serious matter whether satisfactory fuses (in carriers of the R.R. type) made of copper wire Contd. | ||
