[GreenKeys] Nems-Clarke Teletypewriter Switching Unit

Thanks Jim for some enlightenment.

First time I understood what practical use there was for the solenoid 
and switch.  Probably never saw the combination together at once 
before.  I have an RO with the switch, but the printer with it didn't 
have the solenoid.  Printers I've seen with the solenoid weren't with 
keyboards with switches.  I suppose I should have inferred it from WDs, 
but didn't.

So one could program the stunt box to only print when your call sign was 
received or switch to print everything.

It just accomplishes the same thing that little clip does on the left 
end of the code bars does in a more elegant way.
