The Haimu Sea Salt Switch (110-pack) is a high-quality linear mechanical switch designed specifically for custom keyboard enthusiasts. It combines premium materials and craftsmanship with pre-lubrication, making it ready to use right out of the box and ensuring a smooth typing feel. The housing is made of polycarbonate (PC) on top and nylon on the bottom, while the stem is made of POM. Thanks to its 5-pin mounting, it's compatible with many MX footprint PCBs. The spring is a dual-stage design with a length of approximately 22 mm, and the travel specifications are approximately 2.0 mm pre-travel and 3.6-4.0 mm total travel. A modern design with fresh color options (e.g., light blue housing, lemon yellow stem) completes the package.
