| X 7655 RHC.{R. H. Coverley - Production Engineer} from EFC. EFC1/ADL 3.11.30. X.7655. REVISED AUTOMATIC SWITCH TO Lec.2804 INSTRUCTED BY By/RD3/W15.8.30. We have duly received this switch and on inspection we are of the opinion that the leaves making up the spring contact assembly E.72921 should be tried in one gauge thicker material as given alternatively on Lec.2804 though not instructed by By/RD. Will you please arrange to have such a modified spring contact assembly made up as soon as possible as fitted to the switch as soon as we have completed a test of same in its present condition. HEW.
