| X6073 To E.{Mr Elliott - Chief Engineer} from EFC. EFC5/ADLO.3.31. X.6073. R.R. DESIGN OF TWO-WAY SWITCH FOR CENTRAL LAMP SCHEME: We should be pleased to know if you have yet been able to give any attention to the R.R. design of two-way switch. In view of the fact that there has recently been a complaint concerning the loss of voltage in standard head lamp wiring which/have been may due largely to the existence of a changeover switch, we should like to emphasisethe importance of designing such a switch with the absolute minimum loss of voltage through it.
