XY Studio/BSUN Jade Rosales switches are made to be smooth, deep-sounding, reliable, and pretty. The stem is made of Y3X in a brand-new mold. Y3X is an advanced UPE blend with enhanced smoothness and clean sound. The top and bottom housing are made with customized molds for better smoothness and refined top-out and bottom-out sound. Jade Rosales are factory lubed with brand new formulated lube and new lubing machines which BSUN recently acquired. The leaf used on Jade Rosales switches is made with palladium gold alloy to improve its durability. XY Studio also adjusted the leaf spring angle so it would actuate precisely with no leaf noise.

The second QC happens at XY studio, and the third QC was done by Unikeys. 1 quantity = 10 switches Switch Type: Linear Manufacturer: BSUN Designer: XY Studio Stem material: Y3X Top Housing: Modified PC Bottom Housing: Milky thickened housing with industrial adhesive additive Operating Force: 45g Bottom-out Force: 53g Pre-travel: 2.0mm Total Travel: 3.5mm Spring: 20.5mm single-stage nickel-plated spring Factory Lube: Yes.
