See what sits beneath each key.

A keyboard is a stack of fitted parts. Changing one layer can affect what else fits, so start with the exact board and part variants.

  1. Keycap

    The piece your finger touches. Check stem fit, row shape and whether the set covers every key size on your layout.

  2. Switch

    The moving mechanism beneath the cap. Match the switch system to the board and check the exact socket or soldered PCB.

  3. Plate

    Holds many switches in position. Cutouts and mounting style need to match the intended layout and case.

  4. PCB

    The electrical board that receives keypresses. Socket type, layout support and firmware are model-specific.

  5. Case

    The enclosure that supports the assembly. Its dimensions and mounting system set the fit boundary.

FIRST FIT CHECK

Match the exact board version.

Two variants with the same name can have different socket or layout options. Use the manufacturer's variant and PCB details before ordering parts.
