[sdiy] Wiring

[Paul Perry]

Put heat shrink on it. Whatever you do.
Especially if you are worried about multi-strand wire breaking.

They're called solder tags or solder lugs.

Wrapping the wire around the lug makes maintenance harder,
especially with multi-strand wire. (Try it !)

I don't know how much better it is from a mechanical point of
view. In my experience, when a solder joint between multi-strand
wire and a pot breaks, it's the wire itself that breaks, not the
solder. Whether or not the wire is wrapped around the lead.

AFAICS, the main reason for doing this is practical : it removes
the need for a third hand to hold the wire while you solder it.
The usefulness of doing more than half a turn is not clear to
me.

Unless maybe you only solder the end. The extra turns might then
serve as strain relief...
