What customers say
The Kailh BCP Linear Switch earns high praise for its exceptional smoothness and unique sound profile. Users consistently report a deep, resonant auditory experience that sets it apart from standard linears. A key highlight is the performance straight from the factory; the stock lubrication and tight tolerances deliver a near perfect feel, often negating the need for extensive modification. Reviewers appreciate the minimal stem wobble and the satisfyingly quick return from the custom spring. While positioned as a premium option, the consensus is that the BCP justifies its investment for serious builders seeking unparalleled stock smoothness and a specific, high-end acoustic depth. It is highly recommended for dedicated linear enthusiasts.
Know before you buy
The Kailh BCP switches feature a standard MX-style cross stem and a 5-pin mount. They are compatible with most hot-swappable mechanical keyboards that support 5-pin switches, though you should verify your PCB supports the extra two plastic guide pins.
No, these switches come factory lubricated for immediate smoothness. While some enthusiasts choose to apply additional lube for personal preference, they are designed to perform consistently right out of the box.
The 20mm extended single-stage spring provides a snappier return compared to standard-length springs. This creates a more responsive, consistent feel during rapid typing sessions.
The operating force of 52gf is the pressure required to register a keypress, while the 63.5gf bottom-out force is the pressure needed to press the key all the way down. This range offers a balanced feel that is neither too light nor too heavy for most users.
The housing is constructed from durable PA66 plastic, while the stem is made from Dupont POM. This combination is chosen for its low friction and long-term wear resistance, ensuring a smooth keystroke over time.
