Key Switches

🌐中文

This is a KiCad footprint library of mechanical keyboard switches, released under the CERN-OHL-P v2.

Usage

It is recommended to use this library with KiCAD KLE Placer or kicad-kbplacer for automatic switch placement.

If you're using Git, you can include this library as a submodule via git submodule add https://github.com/siderakb/key-switches.pretty.git

Keyboards created using this library: ErgoSNM, Calcite, MS60.

Footnotes

1. Preview images are for reference only and may not be updated with the footprints. ↩

2. Omit the "SW" prefix from the footprint name. ↩

3. Kailh Choc V1 also known as PG1350. ↩

4. Kailh Choc V2 also known as PG1353. ↩

5. Gateron Low Profile 1.0 (aka KS-27) and 2.0 (aka KS-33) footprint are compatible. ↩

6. THT means through-hole soldering. ↩

7. The footprint with "nSilk" suffix means no top layer silkscreen. ↩

8. The footprint with "swap" suffix means the pin number swap. ↩

9. PTH means the holes of the Hot-Swap socket are plated, and the switches can be soldered directly without using a socket. However, the soldering difficulty is higher compared to the standard THT edition. ↩ ↩² ↩³ ↩⁴

10. TTC KS32 and Cherry MX Low Profile are very similar, basically compatible. ↩ ↩²

11. The center fix pin of Choc V1 is smaller than Choc V2, however Choc V1 has two additional fix pins ensuring its stability. ↩ ↩² ↩³

12. The center fix pin of Cherry MX is smaller than Choc V2, however some Cherry MX has two additional fix pins ensuring its stability. ↩

13. The center fix pin of Choc V2 is smaller than Cherry MX Low Profile, Choc V2 may not be securely fastened. ↩
