| E. {Mr Elliott - Chief Engineer} from Hs. {Lord Ernest Hives - Chair} X4431/ HS {Lord Ernest Hives - Chair} 2/LG6.1.22.1 Y4431 STARTER SWITCH FOR GOSHAWK. Referring to Mr. Royce's memo. R2/M29.12.21. We have never had any trouble or have heard of any trouble with the simple form of starter switch used on the Delco, Bijur, Lucas, C.A.V., etc. We are using on the Goshawk cars fitted with the starter motor, a Lucas simple switch which has never given any trouble. The only advantage we can see in the relay switch is that it may be more convenient for operating. Hs. {Lord Ernest Hives - Chair} | ||
