Bsun Roselle Switches

The Bsun Roselle is an innovative mechanical keyboard switch designed for enthusiasts seeking a smooth and unique typing experience. It stands out due to its use of a new material for the stem and specialized manufacturing techniques, resulting in a distinctive feel and performance.

Innovative Stem Material

One of the defining features of this switch is its stem, which is made from Y3, a newly developed material. The introduction of Y3 required the creation of new molds and a custom factory lubing process, ensuring optimal compatibility and performance with the new material.

• Stem material: Y3 (brand new, proprietary material)
• Custom-designed molds for precise fit and finish
• Specialized factory lubing technique for smooth operation

Switch Specifications

This switch is designed as a linear type, offering a consistent and uninterrupted keystroke from top to bottom. Its actuation and bottom-out forces are carefully balanced for both typing and gaming applications.

• Switch type: Linear
• Actuation force: 45g
• Bottom-out force: 52g
• Pre-travel distance: 2mm
• Total travel distance: 3.6mm
• Spring length: 20.5mm

Construction and Materials

The switch is built with high-quality materials to ensure durability and a premium feel. Both the top and bottom housings are made from POM, a material known for its smoothness and longevity.

• Top housing: POM (Polyoxymethylene)
• Bottom housing: POM
• Stem: Y3 material
• Mount type: 5-Pin for secure PCB mounting

Factory Lubed for Enhanced Performance

Each switch is factory lubed using a process specifically developed for the Y3 stem and new mold design. This ensures a smooth keypress right out of the box, reducing friction and unwanted noise.

• Factory-lubed for consistent smoothness
• Reduces friction and enhances overall feel

Compatibility and Installation

The keyboard switch features a 5-pin mount, making it compatible with a wide range of mechanical keyboards that support PCB mounting. This allows for easy installation and a stable fit.

• 5-pin design for secure and stable mounting
• Compatible with most custom mechanical keyboards
