[Antipodal]

Hi there, Thanks both for your very prompt and helpful replies . I am familiar with the setup you describe for setting pushbutton station settings. But this set is a little different. The head unit is separate from the set proper and has two cable drives to operate the manual tuning and the volume.There are also ,in the head unit the push buttons which seem to operate switches ( not mechanical pushbars ) which in turn are connected to a multicore cable which goes into the set.They appear to operate some sort of solenoid which pulls round a selector switch though the schematic is not very clear on this.On the schematic a "device" shown below the 6SK7 r.f. amp seems to have a latch of some sort ,a return spring and a carriage plate all connected to a rotary switch which may be energised by a solenoid. I will keep looking.The schematic appears on Radiomuseum under Motorola Model 605.But thank you for your help.
