Dear Sirs, With reference to our telephone conversation of to-day, we have pleasure in sending you herewith outline drawing N.5.D.H showing the dimensions of our master battery switch. This switch has been approved by the R.A.E., for use on civil aircraft. We are also sending outline drawing N.5.E.O, giving particulars of an alternative switch which can be used as a two way switch for the battery on the craft and a ground battery. These switches are not suitable for use as operating switches and are intended to be switched on or off with the circuit dead. An order for one of each of these switches has been put out on our Works, and these will be forwarded to you as soon as available. Yours faithfully, for ROTAX LIMITED.
