Honeyman - Retail orders} γ 1158 Rm{William Robotham - Chief Engineer}/Std.17/MM.11.5.38. CAR HEATER RHEOSTATIC SWITCH. Further to our request for a suitable rheostatic switch for use with either Clayton or R.R. type car heaters, we send you herewith a list of the test figures which have been taken with these heaters and also some of Messrs.Clayton's performance charts for their heater. We also send you herewith a sample knob which JLE.{J. Lee Evans - Chassis Test Manager} considers suitable for this rheostat switch - see Lc.10/C.3.5.38 attached. We would like to have your design of the switch as soon as possible so that we can get a sample made and tested. Rm{William Robotham - Chief Engineer}/Std. | ||
