| X7650 To EY/RD. from EFC. EFC1/T21.6.26. SEQUENCE SILENT STARTER MAIN SWITCH. Sometime ago we handed to you a combined main and relay switch unit in which the fixed but flexible main switch contact was rearranged in a manner which we had decided was more appropriate for the job, and it was thought that you would rearrange your instructions accordingly. The switch in question has actually been tested and approved. The reason we prefer to have an instruction to the Expl. Shop from you is that it is part of the new arrangement of the Expl. system that everything done in the Expl. Shop is done to official drawing. In fact RHC.{R. H. Coverley - Production Engineer} is at liberty to refuse to carry out a job on actual chassis components unless he has a drawing to work to. MADE AT CROXLEY EFC. | ||
