[Elecraft] CW Paddle A/B switch

[Dave Sublette]

I built, about 20 years ago, a small Bud box, 2 x 2 x 1 3/4, three female
jacks on the back and a DPDT mini toggle switch with center off position.

It has worked perfectly.  The center off position keeps me from sending
when I bump the paddle accidently.
