SOURCE BOUNDARY / EXPLAINABLE COMPARISONFind nearby fields without inventing compatibility.
Start with a switch you know. Candidates remain inside the same electrical system. Low-profile and Hall-effect records also require an explicit retained fit group; ordinary MX results remain physical-fit unresolved until the exact pins, PCB, plate and housing are checked.

Why it appears—and what still differs
Published fields that match- Same MX mechanical system; physical fit remains unresolved
- Same broad linear mechanism label
- Same normalized operating force
- 0.2 mm pre-travel difference
- 0.4 mm total-travel difference
Still unresolved- MX system membership is not a physical-fit verdict
- Different maker family: BOX V1 vs CAP V2
- Factory-lube fields differ: No vs Yes

COMPARE → What this is useful for
It narrows a source register before sample purchase while keeping every result contestable. Similar force and travel can justify a side-by-side test; they never prove interchangeability.
