HMX Saru V2 switches are back! The V1 first released in 2022 as a tactile switch with minimal pre- or post-bump travel. But with recent improvements in this space, we decided to bring back Saru's with HMX. The result is a medium-light, full tactile switch out of the box. After a break-in period, the lube gets more evenly distributed and starts to stand out as a light, full tactile. The combination of a light tactile bump and full tactility creates a unique typing feel that almost feels like a linear – Divinikey. | The Kailh Xuan tactile switch is a light tactile switch designed for enthusiasts who enjoy a clean, clacky, and satisfying typing experience. As the tactile counterpart to the popular Calligraphy linear switch, the Xuan combines a comfortable tactile bump with a lively sound profile that feels responsive and enjoyable for daily typing. The Kailh Xuan uses a premium material combination to achieve its signature sound and feel. MF stem: Produces a crisp and clean clacky sound with a smooth keypress. LCP housing: Enhances overall sound clarity and creates a refined acoustic profile. Light tactile bump: Comfortable and responsive without feeling overly aggressive. Together, these materials create a balanced typing experience with a pleasant clacky character and subtle scratchiness that many enthusiasts enjoy. Like the Calligraphy switches, the Xuan tactile switch features a slight natural scratch that adds character to the typing feel without negatively affecting overall smoothness, making it especially appealing for users who enjoy a more textured typing experience. Perfect for custom mechanical keyboard builds, the Kailh Xuan tactile switch delivers light tactility, clean acoustics, and a uniquely satisfying clacky feel – Unikeys. |
