| To EJJ. c. to RC {R. Childs} /CAP. 6103 General. Rm {William Robotham - Chief Engineer} /RC. {R. Childs} 8/JH.19.1.38. re Switch for Battery Test Rig. With reference to our Rm {William Robotham - Chief Engineer} /RC. {R. Childs} 1/JH.22.12.37. the switch supplied to that request is a huge 200 amp. - 500 volt double pole iron clad switch quite unsuitable for our purpose and unnecessarily expensive. What we require is a simple single pole knife switch of the capacity mentioned similar to a plating circuit switch which we think can be obtained from Cannings. Will you please arrange for this switch to be changed. Rm {William Robotham - Chief Engineer} /RC. {R. Childs} | ||
