Is there any particular plug/socket type connector that is an accepted

Quarter inch phone plug is most common on equipment from the 50's,
60's, 70's. A few use a phono (RCA) plug.

A lot of recent equipment has an 1/8" stereo jack that allows you to
use an iambic paddle on the rig's built in keyer.

There have in the past few months been a couple of QST reviews of
paddles and portable paddles where, for some bizarre reason, the
reviewer assumed that a typical user was incapable of wiring the
connecting plug or correcting the wiring if left and right was
reversed. I thought this was a little odd, but maybe a lot of newbie
hams really cannot wire a plug. I will admit that the cheapie plugs
and jacks from Radio Shack, Mouser, etc., are pretty crappy and melt
the insulator if you are too heavy handed with a soldering gun. The
Switchcraft plugs and jacks (a lot more money than the cheap stuff!)
are a joy to work with.
