Probably not a problem in modern solid-state rigs (and an electronic
keyer would be used in any case). However, that might not be a good
idea for a hand key in some cases :^)
I was thinking the same approach could be used for a single-paddle
design by placing the moving part in the center
Yep. That's what fooled me. I just assumed the center post would be the hot
connection since one normally arranges things to touch only grounded parts.
(Normally doesn't always mean always...).
Might produce some interesting results if there's significant RF around when
touching them.

Well, actually, those clever paper clip paddles will only operate iambic
if you use the center post as ground. That puts the part your fingers
touch at positive potential. Probably not an issue, but I'd feel a bit
better if the finger pieces were ground. That would require the center
piece to be
ample:

A small variation in the center contact and you'd have Iambic paddles.
What an elegant design!

Yep, I think Eric wins the 'Simplest Elegant Award' - real neat, never
felt like making home-brew key or paddles before - still working on my
Morse anyway - but I gotta try that!.
Now, I wonder if Eric would like to start a 'Clipper Kits' business :-)

How about paper clips? I made this one a while back and it works great.

Does anyone have a design for a very simple iambic key that can be made
with simple materials and hand tools? The kids
