Can anyone provide any factual/documented data as to the history of the "Navy Knob" on a telegraph key? I have heard that the flat disc was to guard against electric shocks...and another theory was that the ball aided in stabilizing your "touch" to the motion of the ship's roll in rough seas (hence Navy knob). Hummmm??? Any other theories as well? Thanks!

That's what I have always heard, too.

           Hello,
     Wayne K9DI & Leader Dog Patriot here.  It's amazing that you should raise this question as I was just discussing the origin of the "Navy Knob" with Bob W1ZZL this afternoon.  
     According to Bob the skirt on the "Navy Knob" was to protect the operartor during operation of the early spark gap transmitters.  As the key broke the primary and each time the transmitter was keyed a bright spark would be generated and without the skirt things could get "lively" for the operator.

Just look up the old practice of "plate circuit keying" the cause of many SKs before their time.
