Bear Linear Switches by Xuhua – Premium Thocky Sound and Ultra-Smooth Mechanical Keyboard Switches

Elevate your typing experience with the Bear Switches, a high-performance collaboration with the renowned manufacturer Xuhua. Designed specifically for keyboard enthusiasts who crave a deep, "thocky" sound profile and a crisp, clean bottom-out, these switches offer an exceptional balance of stability and smoothness. Whether you are a competitive gamer looking for rapid response or a dedicated writer seeking a rhythmic flow, these switches provide the tactile consistency and premium acoustics required for a top-tier custom keyboard build.

Key Benefits

Deep "Thocky" Acoustic Profile:** Engineered to produce a muted yet resonant sound, these switches deliver the sought-after "thock" that defines high-end custom builds. The combination of a PC top and PA66 bottom housing ensures every keystroke sounds deep and intentional.

Crisp and Clear Bottom-Out:** Unlike standard switches that can feel mushy, the Bear series features a shortened 3.6mm total travel. This design results in a bottom-out strike that feels incredibly dry, snappy, and responsive.

Self-Lubricating POM Stem:** Utilizing a high-grade POM stem allows for a self-lubricating effect over time. This material choice ensures that the switch remains buttery smooth from the very first click, reducing friction and eliminating scratchiness.

Tailored Weighting Options:** Available in three distinct spring configurations, you can choose the perfect resistance for your typing style. Options range from a feather-light 28g for rapid-fire inputs to a more substantial 45g for those who prefer a deliberate, weighted feel.

Precision Manufacturing by Xuhua:** Produced by one of the industry's most respected factories, these switches boast tight tolerances and minimal stem wobble, ensuring a stable typing surface across your entire keyboard.

How to Use

These switches are compatible with mechanical keyboards featuring MX-style sockets. To install, carefully align the metal pins with your PCB's hot-swap sockets or solder points and press down firmly until the switch clicks into the plate. They are suitable for both RGB and non-RGB builds thanks to the translucent PC top housing. For the best acoustic results, use these switches in a gasket-mounted or foam-dampened keyboard case.

Care & Safety

Store these switches in a cool, dry environment to maintain the integrity of the internal springs and housing materials. Handle with care during installation to avoid bending the copper pins; if a pin becomes slightly bent, gently straighten it with tweezers before attempting to insert it into the socket. Keep away from excessive dust and liquids to preserve the factory-smooth actuation.

Notes

These enthusiast-grade components are designed to ensure that your keyboard's "触底清晰干脆" (bottom-out is clear and crisp) with every single press.
