LUCAS AND R.R. DESIGN OF TWO-WAY SWITCH FOR CENTRAL LAMP SCHEME.
Referring to your memo. EFC1/AD26.1.31 we should like to know the present position regarding the testing of the Lucas two-way switches and the design of the R.R. switch.
As regards the former, we have already mentioned that we, at this end, did not consider these switches to be of the same standard as the Bosch two-way switch which we are now using.
