A smooth, silky light 41gf linear with TTC's long guide-rail stem for wobble-free travel, a lengthened 21.5mm spring, and POM-on-POM contact — factory-lubed and sorted straight out of the box.
Read the full description
The TTC Neptune is a 5-pin linear switch built for a smooth, silky keystroke straight out of the box. With a light 41gf operating force and a 2.0mm actuation point, it's an easy-going linear suited to fast gaming inputs and relaxed, low-effort typing alike — a well-rounded pick for anyone after an effortless feel without a heavy press.
The standout is TTC's long guide-rail stem structure (marketed as the "high-speed rail" design), which lengthens the stem's contact track versus a standard switch for steadier, wobble-free travel along the full stroke. Paired with a lengthened 21.5mm spring, the return is springy and consistent across the 3.8mm total travel, with a clean reset that keeps rapid presses feeling crisp.
Materially, the Neptune runs a POM stem and POM top housing over a polycarbonate bottom. The POM-on-POM contact gives the switch its characteristic smoothness, while the PC bottom lends a slightly rounded, controlled sound rather than a sharp, high pitch. Factory lubrication is applied from the start, so there's no scratch to break in — these feel sorted the moment they're installed. The transparent housing also lets per-key RGB shine through cleanly.
Rated for 100 million keystrokes, the Neptune is a durable, no-fuss linear that lands well for both first-time switch swappers and enthusiasts who want a smooth stock option without lubing.
