Bsun Dragon Linear Switches

The Bsun Dragon Linear is a smooth linear switch available in two actuation force options, suited for users who prefer consistent keystrokes without tactile feedback. It fits well for gamers or typists seeking a light to moderate keypress with minimal resistance and a straightforward feel. The switch’s moderate travel and factory lubrication aim to provide a balanced typing experience, though it may require additional tuning for optimal smoothness.

Actuation Characteristics

• Two force options: 33g actuation with 40g bottom-out force, and 42g actuation with 50g bottom-out force, allowing choice between lighter or firmer keypresses.
• Short pre-travel of 1.6mm supports quick key registration, beneficial for fast typing or gaming.
• Total travel of 3.8mm provides a standard keypress depth, balancing speed and comfort.
• Bottom-out feel is moderate, giving tactile feedback through resistance rather than a bump.

Build Quality

• Stem made of POM (polyoxymethylene), a material known for smooth sliding and durability.
• Top housing is polycarbonate, which can slightly affect sound profile by producing a crisp but not overly sharp tone.
• Bottom housing uses PA66 nylon, contributing to structural stability.
• Includes a 22mm spring, standard length for consistent force delivery.
• Factory lubrication is applied, which reduces initial scratchiness but may benefit from additional lubing for smoother operation.

Compatibility

• PCB mount design with 5 pins ensures secure installation on compatible PCBs.
• Standard MX-style stem allows compatibility with most keycaps designed for MX switches.
• Unknown hot-swap compatibility, so suitability depends on the keyboard’s PCB.

Trade-offs

• Linear feel means no tactile bump, which may be less satisfying for users who prefer feedback on actuation.
• Some users may notice minor scratchiness despite factory lube, common in budget switches.
• Sound profile is moderate but not optimized for quiet typing environments.
• Unknown long-term durability and spring noise characteristics.

Use Cases

• Good for gamers who want fast, consistent keypresses without tactile interruptions.
• Suitable for typists who prefer smooth, light to medium resistance keys.
• Less ideal for office settings requiring quiet or tactile feedback.
