| X7655 To RHC.{R. H. Coverley - Production Engineer} from EFC. c. HS{Lord Ernest Hives - Chair}/AJL. EFC/T14.5.29. PUSH BUTTON SWITCH FOR 23-EX. The duplex automatic switch has already been handed over for this chassis, having passed test satisfactorily. The starter motor is at present with us for test and we hope will be passed to you shortly for fitting to 23-EX. We are, however, concerned about the push button switch which should be produced to IY/RDB/N10.5.29. We also require a duplex push button switch for our rig - to replace the one recently handed over for 9-EX. This is rather urgently required to enable us to proceed with the arrangement of automatic switch for testing gear ring materials. EFC. | ||
