Hello, I have keyboard (year 1995) with black clicky space invaders without a logo. The keyboard looks like in excellent condition, but the key travel is not smooth (almost stucking). I would like to clean them and grease, and maybe to remove clickers. As far as I understood, it is impossible to disassemble without breaking anything. What do you think about this? Will soldering off help?

De-soldering Hi-Tek "Space Invaders" is very difficult, even removing caps must be done with great care.
Also, the click mechanism is integral to the construction of the switch. I have not taken one apart in several years, but as I remember there is probably no way to remove it.

Makes me wish I had grabbed one from the recycling place the last time I saw a few, then I might know.

Whoa! Never pass up clicky "Space Invaders" they are one of the very best switches out there, although they are extremely delicate and fussy to try to work with.
The "legs" are just wires, and there is no strain relief, so you have to remove all of the original solder to get them off.

I have never bad an issue damaging space invaders by taking the sliders out. You just have to pull up on them and make sure to not let the spring go flying across the room which is pretty hard most of the time. Just make sure to not damage the contacts when taking the slider off or putting it back on, they do bend easily but can be fixed if you don't crumple them.
I have taken apart a few boards worth to clean an never had a switch issue because of it.

They seem relatively common to me. I see them on Ebay for reasonable prices pretty often, and the recycling place had at least 2-3 of them in a single visit. I think the only thing they had more of was Model Ms, and those weird SKCC cream terminal boards from the early 80s. They do feel nice, for sure, but I was already leaving the place with a Zenith Z-150, a metal badge M, a Fujitsu with Peerless switches, and one of the SKCC boards, and I had already tossed them $200 for those. lol

Thank you for sharing your experience! I think I will succeed, I will be attentive to flying springs))
