You will notice that the Cover and Base are of Aluminium; this is a temporary measure and when the Switch is finally settled these will be Bakelite Mouldings. We have arranged for the necessary insulation where required. With reference to the coils, there are alternative sets issued to EFC's request. The "Glowray" resistance wire is obtainable from The Purit Specialities Ltd., Park Street, Birmingham. The Gold-Silver Contacts are the same mixture as used on the 20 H.P.
