Referring to your memo Rm.{William Robotham - Chief Engineer}7/R.25.11.36, we agree there is some difficulty in finding the instrument board light switch on the Phantom III when one is not accustomed to driving the same car always. In the new type of adjustable rheostat switch we are locating the knob at the bottom of the instrument patch pointing vertically downwards, so that it will only be necessary to run the hand along the bottom edge of the instrument board to find this switch.
