This is what I gather from AliExpress.
From this listing for the sp star switches:
The original star switch is 67g tactile. You can see the force curve diagram in the listing. It looks to me somewhat in line with a v1 zealio graph. Pre-travel with a short but defined bump.
The grey stem sp Star is linear. I’m fairly certain the crafting keyboard site has these two variants listed incorrectly.
Both of these variants are 3pin, plate mount.
Then you have the newest variation, the Kon Momo and Nana. Both are 5pin, 65g spring weight.
Momo is the newest tactile variant with a harder polymer housing, also transparent for a different aesthetic. I think they’re trying for a crisp and louder switch. I’m thinking this is more in line with a T1 or Holy Panda.
Nana is the linear option in a nylon housing. Should sound deeper. I believe the OG star above had this same material. These sound interesting to me. Of course, nylon tends to be less smooth, so I would assume they will need to be lubed.
The crafting keyboard site and eBay are charging $2 per switch… AliExpress is much cheaper with volume discounts at $0.65 per switch with shipping. However, the estimated delivery is close to six weeks.
