| RHC.{R. H. Coverley - Production Engineer} from EFC. X7655 EFC3/ADL 3.11.30. X.7655. MAIN STARTER SWITCH TO Lec.2804. In view of the fact that an endurance test of this switch was called for on the LeC and that one of these switches is to be fitted to 27-EX, we consider we ought to have a second switch to the above mentioned LeC. For this purpose we hand to you our experimental switch representative of present standard, which will you please have modified at your ealiest convenience so as to produce another one to Lec.2804. The main flexible copper contact in this case should be similar to the one with leaves of thicker gauge as asked for in our previous note EFC1/ADL3.11.30. We propose to proceed with an endurance test on the switch we have at present so that the one now asked for will, after test, be allocated to 27-EX. HEW. EFC. | ||
