KS27 KS33 Hotswap footprint hole too big.

[Finnitio]

I just received pcbs and the hole diameter is too big with 5.25 mm. The switches are completely lose and only stay loose in place due to the hotswaps.

Thanks for reporting this! Only got to check it out now...

The footprints are following Gaterons recommended landing pattern, which is quite confusing. I wonder how wide I should make the hole.

Kailh Choc have a 3.2mm center pole and the recommended footprint states 3.4mm, so 0.2mm "clearance" just like Gateron did here. That seems to work fine on Kailh. I wonder why it does not on Gateron.

Did you measure the actual hole with calipers to make sure the factory did not make a mistake and used the wrong drill bit?

I did not measure them, but considering the other drawing it is obvios that there is some play in the contact pair.
