Quick Summary

The Kailh BCP is a factory recreation of the old Black Cherry Pie frankenswitch: a Cream-style POM stem dropped into nylon housings. It is a 52g linear with a distinctly clacky, slightly dry voice that lands between a smooth daily driver and a character switch. If you liked the original BCP’s poppy nylon sound but never wanted to assemble one by hand, this is the easy way in.

Specs and Feel

This is a short-throw linear: roughly 1.4mm pre-travel and 3.5mm total travel, with a 52g actuation rising to about 63.5g at the bottom. The 20mm single-stage spring keeps the push fairly even rather than ramping up hard at the end. The stem is the same Cream-style POM, and both housings are PA66 nylon with no fiberglass, which is exactly what gives this switch its clacky, woody pop instead of a glassy click. Smoothness is good but not glass. There is a faint POM-on-nylon graininess that some read as creamy and others as light texture. The bottom housing is thickened versus the original recipe, so it reads a touch deeper and less rattly. Factory lube is present and helps.

Tuning

It is usable stock, which is the whole point of buying the recreation. That said, the POM/nylon pairing responds well to a thin coat of 205g0 on the rails plus a dab on the spring. It pushes the slight texture out and lets the nylon thock breathe. Films are mostly unnecessary because the BOX-adjacent stem already keeps wobble low; spend your effort on lube and a good keycap set instead.

Verdict

Buy the Kailh BCP if you want a nylon-housed clacky linear with personality and you would rather not source a Cream stem and Cherry housing yourself. It is louder and more characterful than a smooth-and-quiet Gateron Milky Yellow, and warmer than a polycarbonate BOX linear like the Box Black. Skip it only if you want dead-silent smoothness; the nylon clack is the point of the switch.

Frequently asked

How heavy is the Kailh BCP?

It actuates around 52g and bottoms out near 63.5g, so it sits in medium-weight territory, firmer than a 45g daily linear but a long way from a heavy switch.

Does it need lube?

It comes factory-lubed and is fine stock, but a thin coat of 205g0 on the rails and spring cleans up the slight nylon graininess and lets the clack ring out.

What does it sound like?

Clacky and woody. The fiberglass-free PA66 nylon housings give it a poppy, slightly hollow tone rather than the glassy snap of a polycarbonate switch.
