Bear Switch by Xuhua | High-Performance Muted Linear Mechanical Switches

Elevate your custom keyboard build with the Bear Switch, a premium linear switch manufactured by the renowned Xuhua factory. Designed specifically for enthusiasts who crave a deep, "thocky" acoustic profile and a refined tactile feel, these switches offer a sophisticated typing experience. By combining high-quality materials with precision engineering, the Bear Switch provides a stable, smooth, and consistent keystroke that is ideal for both high-speed gaming and long-form professional writing.

Key Benefits

Self-Lubricating POM Stem:** The stem is crafted from high-grade POM material, which is naturally low-friction. This ensures a buttery-smooth glide right out of the box that actually improves over time as the material "breaks in."

Signature Muted Sound Profile:** Engineered for a "muted" yet resonant sound, these switches utilize a PC top and PA66 bottom housing to dampen harsh high frequencies. The result is a concentrated, deep acoustic that keyboard enthusiasts highly prize.

Enhanced Housing Stability:** Xuhua’s manufacturing process ensures tight tolerances between the stem and the housing. This significantly minimizes stem wobble, providing a secure and centered feel for your keycaps even during off-center presses.

Advanced Spring Dynamics:** Available in three distinct configurations, the Bear Switch utilizes specialized springs to fine-tune your typing. The light 28g version features a 21mm double-stage spring for a faster, snappier rebound, while the 37g and 45g versions offer traditional single-stage consistency.

Crisp Bottom-Out Feel:** Despite the smooth travel, the switch provides a definitive and clean impact at the end of the stroke, ensuring you receive clear physical feedback for every actuation.

How to Use

The Bear Switch is compatible with standard MX-style mechanical keyboards and keycaps. These switches can be easily installed into hotswap-compatible PCBs or soldered into custom keyboard plates. Before installation, ensure the metal pins are straight. Align the pins with the sockets on your PCB and press down firmly until the switch clicks into the plate.

Care & Safety

To maintain optimal performance, keep your keyboard in a dust-free environment and avoid exposure to liquids. If a pin becomes bent during transit or installation, use a pair of tweezers to gently straighten it before attempting to insert it into a socket. Store any unused switches in a cool, dry place to prevent oxidation of the internal metal contacts.

Notes

The Bear Switch is specifically engineered so that the "bottom-out is crisp and clean," providing a high-end feel for any custom mechanical keyboard project.
