Why rotary-tip on 4mm banana plugs?
tooki:
Yep, totally agree about the terminology! (And having been to north Florida many, many times, I can confirm that gators are everywhere there!)
Please fix the quoting in your reply, though. Your reply is inside the quote, and the quote is misattributed.

There is also this style, I'm not sure if any major manufacturers make them:
The 4th style, IMO, is the best in terms of reliable low contact resistance as far as I've seen. I've had all the other styles degrade over time, even from major manufacturers. These multi spring style ones seem to hold up better? The downside is of course its a bit harder to insert.
Here you can see Hirschmann rate them 30A and 3mOhm contact resistance:

hah while I was searching I saw this photo:

I want to second that, I've tried a few different styles and I think this one is the most reliable/durable for the money:
DELTRON COMPONENTS 550-0500 (there are variations of part numbers for different colours).
It does go in a bit harder but the contact is superior.
The OP's type, I was using that one for a while, until the thing snapped inside of the psu and took me hours to get little pieces out.
tooki:
I’ve used many of the Deltron 553 series (the stackable banana) and they work well.
