SMK second generation switch - looking for datasheet

I've already checked this page:
wiki/SMK_second_generation

I'm designing a PCB and backplate for a keyboard that will be using SMK switches. The variety I have is the second generation, tactile Alps mount variant. I already know that the square hole on the backplate is 14mm square. What I need are the precise measurements for the two leads on the switch, so that I can create a part in my PCB software. A datasheet would have given me all this information. Thank you!

You’re making a PCB for Montereys? Good on you. They’re fantastic.

Best of luck sourcing the info. Nothing an existing keyboard’s PCB and some callipers could do?

LFKeyboards are sharing their PCB footprints, including footprints for SMK here:
https://github.com/lfkeyboards/public/t ... ard.pretty

They have used these for PCBs for sale, including for SMK in 65%, "78%" and TKL, so I suppose they have been tested.
