THE BIT THEY DIDN'T PUT ON THE BOX.
Clicky switches. Quietly enormous margins.
Custom keyboard shops sell packs of 10 performance switches to consumer hobbyists for £8–£12. Sourcing the exact same manufacturer part numbers (like Outemu or Gateron) directly from commercial electronic component distributors (like Mouser or AliExpress industrial) drops the unit cost to under £0.15 per switch.
SO WHAT'S THE CATCH?
£1.50 is an inferred ten-unit equivalent from the supplied under-£0.15-per-switch figure.
“The interesting bit isn't the badge. It's what happens when you search for the part behind it.”
THE INTERNET DETECTIVE'S CHECKLIST
Look for complete part numbers and revisions, make sure you're comparing the same quantity, and check the exact model/application. That's especially important with electrical, braking, steering, battery and other safety-related components.
