Bsun Jade Rosales Linear Switches

The Bsun Jade Rosales Linear is a smooth, linear mechanical switch designed for users who prefer consistent keystrokes without tactile bumps or clicks. It suits gamers and typists seeking a light actuation force with a moderate total travel distance. Its factory lubrication and polycarbonate housing aim to provide a quieter, smoother typing experience. This switch fits standard MX-compatible keyboards with PCB mount support.

Feel & Sound

• Linear feel delivers smooth keypresses without tactile feedback, making it suitable for fast, uninterrupted typing or gaming.
• Factory lubrication reduces scratchiness, contributing to a quieter and softer sound profile.
• Pink polycarbonate housing may produce a slightly muted sound compared to harder materials, but overall noise level is moderate.

Actuation Characteristics

• Light actuation force of 45g allows for quick key activation with less finger fatigue during extended use.
• Pre-travel of 2.0mm and total travel of 3.5mm balance responsiveness with a comfortable bottom-out distance.
• Bottom-out force of 53g provides a noticeable but not harsh resistance at the end of the keypress.

Build Quality

• Modified polycarbonate top housing and custom milky bottom housing offer durability and a smooth keystroke feel.
• 20.5mm nickel-coated spring supports consistent force and reduces spring noise (spring ping).
• Y3X stem design ensures compatibility with MX-style keycaps and stable keypresses.

Compatibility & Mounting

• PCB mount with five pins provides secure installation on compatible PCBs but may not fit hot-swap sockets designed for plate mount switches.
• Standard MX stem supports a wide range of keycaps, including aftermarket options.

Trade-offs

• Linear design lacks tactile feedback, which may be less satisfying for users who prefer a bump or click.
• While factory lubed, additional lubrication could further reduce any residual scratchiness, but this depends on user preference.
• Unknown long-term durability and break-in behavior due to limited data.
