Leading the way in linear switch performance, the Kailh Jellyfish switch has many of the benefits of its namesake—with almost none of the drawbacks. Part of Kailh’s Box and Master Series, the Jellyfish features durable polycarbonate housings, a high-molecular polyamide stem, and a Master-Series-exclusive structure to improve service life. And with corrosion-resistant, gold-plated hardware, it’s anything but fragile. Requiring a moderate 50 grams of force to actuate, it has 4 millimeters of total travel. Plus, it’s factory pre-lubed, so it takes to each keystroke like a (jelly)fish to water. Alongside its linear smoothness, a transparent stem and housings add to the jellyfish similarities. Great for showcasing RGB lighting, these transparent components also reveal the gold-plated spring—which measures a lengthy 18 millimeters to minimize noise and maximize rebound.
