First seeing this on my home feed on Jan 7th. Relieved to find the post is 5 days old…

That’s great. Thank you again!

Thank you! Something concrete to go on. Is there a specific name these go by? I couldn’t find them by searching.

I think I have two issues to work through. I’m not sure I applied enough pressure to actuate the spring (access may be a limiting factor in-situ), and I was using an extremely fine gauge of wire. I doubt it would have the stiffness to push in.

Would a stalk lug work to provide added stiffness to the conductor, or does this terminal expect something malleable?

That was my initial thought, but there’s little to no give in the orange button. If anything it only felt like a little play you get between loosely coupled mechanical pieces. That’s when I tried operating it like a clamp and broke one off.
