Top-Tier Custom Frankenswitch Replica
Kailh BCP Linear Switch
Tired of the endless sea of ultra-light, hollow-sounding linears? Miss that incredibly solid, deep, and satisfying bottom-out that only true vintage mods can provide?
For years, hardcore custom keeb enthusiasts spent insane amounts of money and hours disassembling multiple switches just to frankenswitch the perfect feel—the legendary BCP (Black Cherry Pie). Now, Kailh and Off Studio have officially resurrected this legend in a mass-produced masterpiece.
This isn't just a switch; it's a love letter to the endgame typing feel. Faithfully reproducing the exact recipe—a thickened PA66 Nylon housing with that classic Cherry frosted texture and a Dupont POM stem—it delivers that coveted "gritty yet incredibly solid" feedback. Packed with a medium-heavy 52gf operating force, a lightning-fast 1.4mm actuation, and a snappy 20mm KOS extended spring. Skip the hours of tedious hand-lubing and splicing. The Kailh BCP arrives perfectly factory pre-lubed, ready to deliver that deep, muted thock straight out of the box.

Core Advantages: Why the BCP is the Ultimate Linear Endgame
We know you miss the authoritative, grounded keystroke of old-school switches, and you're sick of floating on mushy, pingy modern linears. The Kailh BCP strikes the absolute perfect balance between "thick and solid" and "snappy and fast."
The Problem: Hollow & Cheap Ping
Modern lightweight linears often use soft plastics to achieve smoothness, resulting in a hollow, scattered bottom-out sound heavily plagued by high-pitched clacks or metallic spring ping.
The Problem: Fat-Fingering & Mushiness
The market is flooded with 30-40g feather-light switches. For heavy typists or intense gamers, this means constant accidental misinputs (fat-fingering) and a sluggish, mushy rebound that ruins rhythm.
The Problem: The Frankenswitch Hustle
Building a true BCP used to require buying three different switch sets, dismantling them, hand-lubing, and reassembling. It cost over $1.50 per switch and wasted dozens of hours of your life.
✨ Kailh BCP Linear Switch: PA66 Nylon + Dupont POM, 52gf snappy KOS spring, and factory pre-lubed. The legendary muted thock, zero assembly required.
End Hollow Ping
100% Authentic BCP DNA & Deep Muted Thock
The Legendary Recipe
Faithfully replicates the exact material formula of the legendary frankenswitch: a thickened PA66 Nylon housing (retaining the pure, classic Cherry frosted texture) paired with a premium Dupont POM stem.
Absolute Advantage
This specific material clash entirely absorbs sharp collisions. Instead of a loud, scattered clack, you get an incredibly concentrated, warm, and low-frequency "Muted Thock."
Sensory Benefit
Every keystroke is premium ASMR. It retains that addictive "gritty yet solid" physical feedback that old-school enthusiasts obsess over, turning typing into a profound acoustic art.
End Misinputs & Sluggishness
52gf Authority & 20mm KOS Snappy Spring
Golden Specs
Precision-calibrated to a medium-heavy 52±2gf operating force with a solid 63.5gf bottom-out. Internally powered by Kailh's renowned 20mm KOS (Kailh Optimized Spring) extended single-stage spring.
Absolute Advantage
The 52g force provides a highly confident, authoritative press that completely prevents accidental fat-fingering. The 20mm spring guarantees a ferocious, snappy rebound.
Gameplay Benefit
Absolute control meets lightning-fast reset. The harder you press, the more satisfying the bounce-back. Your rapid touch-typing and gaming combos will feel incredibly grounded and rhythmic.
End The Modding Hustle
1.4mm Fast Actuation & Factory Pre-Lubed
Hardcore Architecture
Integrates an aggressive 1.4mm ultra-short actuation point. Features a rock-solid 5-pin (PCB Mount) base and undergoes high-precision automated factory pre-lubing on the rails and springs.
Absolute Advantage
The 1.4mm travel gives this heavy switch esports-grade speed. The factory lube perfectly smooths out any unwanted spring ping, and the 5-pin design ensures zero horizontal stem wobble on plateless boards.
Setup Benefit
Save yourself hundreds of dollars and dozens of hours of tedious splicing. You get the peak, endgame BCP experience straight out of the box. Drop them in and dominate.

"This is exactly the BCP I've been waiting for!"
"The feel is incredibly authentic! That solid, slightly gritty yet premium feedback, combined with the extremely muted, deep bottom-out sound, is exactly what making a frankenswitch BCP used to feel like. Factory lube is fantastic. I don't have to ruin my hands splicing switches anymore. Absolute endgame."

"An absolute blessing for heavy-handed FPS players."
"The 52g operating force is perfect for me. I have heavy hands and constantly fat-finger light switches, but this switch gives me total control. The 1.4mm actuation is insanely fast for CS2, and the 20mm spring snaps back beautifully."

BCP (Black Cherry Pie) is one of the most legendary "Frankenswitches" in the custom keyboard community. Years ago, enthusiasts seeking the ultimate deep, solid sound and feel would buy three different switches: a Cherry top housing, a JWK black bottom housing, and a Kailh Cream POM stem. They would dismantle them, hand-lube them, and splice them together. This process was extremely expensive (over $1.50 per switch) and took hours. By partnering with Off Studio, Kailh has officially mass-produced this legendary recipe (thick PA66 housing + Dupont POM stem), allowing you to experience this top-tier endgame feel at an accessible price, straight out of the box.
It falls right into the "Medium-heavy" category. If you are used to ultra-light red or silver switches, it will definitely feel substantial at first. However, the biggest advantage of this weight is absolute control. In tense FPS games, it completely prevents accidental "fat-finger" misinputs. Combined with the ultra-fast 1.4mm actuation and the snappy 20mm extended spring, it provides an incredibly confident, physical confirmation that makes esports and high-speed typing feel incredibly grounded.
Absolutely not. The Kailh BCP switch is precision factory pre-lubed on the rails and springs using automated equipment. It is designed to be a true "ready-to-use" product. The vast majority of enthusiasts agree that its smoothness and acoustic profile already meet high-end custom standards out of the box, saving you the massive headache of re-lubing.
Standard smooth linears typically chase absolute silence or a sharp, high-pitched "clack." The soul of the BCP, however, lies in its "solidity." The collision between the Dupont POM stem and the PA66 Nylon housing creates a very low-profile, muted, and incredibly thick bottom-out sound (often described as a deep "Thock"). It lacks any sharp plastic collisions or metallic spring ping, making it sound intensely premium and grounded—an absolute favorite for heavy Thock lovers.
Yes, you can! The two extra plastic legs on the bottom of the Kailh BCP switch provide extra stem stability and eliminate horizontal wobble on plateless PCBs. If your PCB only supports 3-pin switches, simply use nail clippers or flush cutters to snip off those two side plastic legs flat against the base. They will fit perfectly, and doing so will not void your warranty or affect the switch's functionality in any way.
