# Cherry MX PCB-mount stabilizer holes (2u, 2.25u, 2.75u, 6.25u)

> Where do the stabilizer holes go for 2u, 2.25u and 6.25u keyboard keys?

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Keys 2u and wider (Shift, Enter, Backspace, numpad 0, spacebar) carry a wire stabilizer: two housings, one each side of the switch, joined by a wire so the key goes down level when pressed off-centre. PCB-mount (Cherry-style) stabilizers clip or screw into two holes per housing.
- Spacing is the same for 2u, 2.25u and 2.75u keys (housings 23.8 mm apart, ±11.9 mm from the switch) and 100 mm apart for a 6.25u spacebar (±50 mm), positions from the KiCad Cherry MX footprints. The small Ø3.05 hole is on the switch-pin side, the large Ø4.0 hole opposite (same y-up, keycap-side view as the switch footprint page).
- The files are drill jigs at true size: a ring round every hole (switch and both housings) joined by bars, to print and drill through or to import as the exact hole pattern.

## Sizes

| key | stabilizer |
|---|---|
| 2u key | housings at ±11.9 mm (23.8 mm apart) |
| 2.25u key | housings at ±11.9 mm (23.8 mm apart) |
| 2.75u key | housings at ±11.9 mm (23.8 mm apart) |
| 6.25u key | housings at ±50 mm (100 mm apart) |
| small hole (each housing) | Ø3.05 at y = +7.00 mm |
| large hole (each housing) | Ø4.0 at y = −8.24 mm |
| vertical 2u (numpad + / Enter, ISO Enter) | housings at ±11.9 mm along the key's long axis |

## Questions

**How far apart are 6.25u spacebar stabilizers?**

100 mm: each housing 50 mm from the switch centre.

**Do 2u, 2.25u and 2.75u keys use the same stabilizer?**

Yes: housings ±11.9 mm from the switch (23.8 mm apart) for all three.

**What size are PCB stabilizer holes?**

Two per housing: Ø3.05 at 7.00 mm towards the switch-pin side and Ø4.0 at 8.24 mm on the other side.
