I'm a newbie guitar maker. I wanted to be able to quickly swap out pickups or capacitors. I saw other vendors selling pots with these preinstalled, so I thought I'd try it myself. The tines were just a little too thick to fit into the free-way 10 position blade switch I used, so I ended up soldering solid core wire to bridge the gap. Otherwise, they fit nearly perfectly into everything else.
These work great. My only complaint is that when I stuffed multiple pre-tinned wires into a slot (most were 22 gauge, some was 24 gauge), sometimes they wouldn't stick when screwed into place. I think if I hadn't tinned them, or if they were all the same gauge, it wouldn't have been a problem. Also, the silicone coating on some of them was really thick, which made it harder to stuff other wires into the same slot. My workaround was to solder those wires together before putting into the slot, which kind of defeated the purpose of them. But, it was a great learning experience.
Finally, the provided screw driver works, but you have to pay attention to the angle more than other drivers if you want it to work.

They stack mechanically. I found it easier to build them up one piece at a time on the board. If you stack a run of them and then try and insert them onto a prototype board it’s just about impossible.
