With correct bedding of this switch there will be no trouble due to the passage of the heavy current at this point. It may be advisable by making the cores taller to reduce the air gaps in the 'on' positions of the levers of the two units. As already arranged, this involves reducing the stop,originally .050", on the main switch lever as has been done in this particular model. We return the switch herewith to RHC.{R. H.
