What customers say
Enthusiasts highly regard the Kailh MX BCP Custom Linear Switch, primarily for its outstanding acoustic profile. Users consistently report exceptional smoothness, often noting the effective factory lubrication. The long pole stem design generates a distinct, satisfyingly poppy sound on bottom out, which many find superior to standard linears. This unique sound signature makes the BCP a top selection for those prioritizing acoustic performance and a crisp typing feel. While the design contributes to a perceived faster actuation, a few users note the bottom out can feel slightly harsher. Overall, the consensus confirms the BCP offers superb build quality and a truly unique typing experience that justifies its premium positioning.
Know before you buy
The long-pole stem design results in a shorter total travel distance of 3.5mm and a firmer, more immediate bottom-out feel. This design contributes to the switch's signature 'clacky' sound profile by creating a harder impact when the stem hits the bottom housing.
No, these switches come pre-lubricated from the factory for smooth operation right out of the box. While some enthusiasts may choose to apply additional lubricant to suit their personal preferences, they are designed to perform well without any extra work.
These are standard MX-style switches, meaning they are compatible with most mechanical keyboards that use Cherry MX-style sockets. They will work with any MX-compatible keycap set.
With an actuation force of 52g and a bottom-out force of 63.5g, these switches offer a medium-weight feel. They provide enough resistance to prevent accidental key presses while remaining light enough for comfortable long-term typing or gaming.
These are a production-grade alternative designed to replicate the feel and sound of the original BCP using new, high-quality housing molds. They offer a more consistent experience than the original 'Frankenswitch' method, which required combining parts from different manufacturers.
