| X8660. C. EFC. BY/RDS/ML12.11.25. RE E.A.C.11 AUTOMATIC SWITCH - SEC:8660. Please receive herewith blueprints of the following parts representing an alternative scheme for securing the non-inductive resistance on the above switch. D.71013 - Resistance Frame. D.71015 - Stud for Resistance Frame. D.71016 - Assembly of Resistance Wire and Frame. D.71017 - Screw. Will you please put this in hand and compare same with the present bobbin type, the new one we think will be much more robust. BY/RD. | ||
