Hi Lawrence,
I'm not sure if I am entirely qualified to answer that question. As far as I can see there are three switches on this unit: One switch that cuts or connects the mains to the power transformer. This switch is actually controlled by the 1000K volume pot in that there is a "metal tag" at the far end of the potentiometer that opens or closes a toggle switch that goes to the mains/OT. Clever little device. I just left it out of the "caveman's schematics" to simplify things. Above the volume pot/power switch, there is another toggle switch, that connects something-something to one of the (I would presume) RF coils? From my overly primitive sketches, it seems like the switch simply connects one of the leads from the coil to ground, if that makes sense. The last and third switch is the one on rear end that you saw in my previous drawing. I'll try make a schematics for the entire receiver as soon as I'm able to.
