Bsun X Switches

The Bsun X is a mechanical keyboard switch designed for enthusiasts seeking a unique typing experience. It stands out due to its innovative use of materials and precise engineering, offering a smooth, clacky, and durable performance for demanding users.

Material Innovation

A defining feature of this switch is its use of polyketone (POK) for both the top and bottom housing. POK is a relatively new material in the switch market, notable for its exceptional properties:

• Extremely low coefficient of friction (0.04), making it one of the smoothest materials used in switch manufacturing.
• Outstanding durability, with wear resistance 14 times greater than POM.
• Superior shock resistance, 2.3 times better than Nylon and 1.4 times better than POM.

These attributes result in a switch that is not only smooth and satisfying to use but also highly resistant to wear and impact over time.

Switch Characteristics

This model is a linear switch, engineered for a consistent and uninterrupted keystroke. Its construction and specifications are tailored for both performance and comfort.

• Stem Material: Modified LY, contributing to the switch's smoothness.
• Top and Bottom Housing: POK (polyketone) for enhanced durability and a distinct clacky sound profile.
• Operating Force: 45g, providing a light and responsive feel.
• Bottom-out Force: 52g for a balanced typing experience.
• Spring: 21mm single-stage extended spring, ensuring a consistent return and smooth actuation.
• Pre-travel Distance: 1.6mm for quick key registration.
• Total Travel Distance: 3.5mm, slightly shorter than standard for faster actuation.

Factory Lubrication

Each switch comes pre-lubricated from the factory, enhancing the smoothness and reducing friction even further. The lubrication process includes:

• A mix of 205 and 105 lubricants applied to the sliders.
• Dry film lube on the sides of the stem and on the spring.

This meticulous lubrication ensures a refined and consistent keystroke right out of the box.

Sound and Feel

The combination of POK housing and modified LY stem delivers a unique auditory and tactile profile. Users can expect:

• A distinct, clacky sound signature that stands out from conventional switches.
• Exceptionally smooth keypresses with minimal friction.
• Durability that maintains the switch's feel and sound over prolonged use.

Summary of Features

• Linear switch design for smooth, uninterrupted keystrokes.
• Innovative POK (polyketone) housing for superior durability and smoothness.
• Modified LY stem for enhanced glide.
• Light operating force (45g) and balanced bottom-out (52g).
• Extended 21mm spring for consistent actuation.
• Factory-lubed for optimal performance.
• Unique clacky sound profile.
• Pre-travel: 1.6mm; Total travel: 3.5mm.

Conclusion

This switch is an excellent choice for keyboard enthusiasts who value innovation, smoothness, and durability. Its advanced material composition and thoughtful engineering make it a standout option for anyone looking to enhance their typing or gaming setup with a distinctive and reliable switch.
