The Jam Ice Cream switch is a linear switch jointly customized by Jianlu and Kailh, part of the Ice Cream Universe series. With its unique design and outstanding performance, it is the perfect choice for gaming and typing enthusiasts. Design: The switch stem features a vibrant berry red color, while the housing is a creamy off-white. The overall aesthetic is visually appealing and comfortable. Material: The switch stem is made of PUK material, and both top and bottom housings are crafted from POM, ensuring durability and a premium feel. Special coating: Both pins have an anti-oxidation coating, enhancing longevity and stability. Light guide: The high-transparency PC light guide provides excellent light diffusion and a glowing effect – diykey. | The HMX Lunar Stone linear switches are manufactured using HMX's brand-new full POM housing mold. It is the first full POM HMX switch. As the first full POM HMX switch, we expected it to sound and feel a bit different from other HMX switches in the market. They have proven to be quite unique; They sound fuller and thockier than most HMX switches yet still come with the bassy bottom-out sound. The travel feels very smooth yet there is audible scratch since that's what most people love about full POM switches – Unikeys. |
