GATERON Jupiter Red Keyboard Switches Linear 45gf RGB LED 5 Pin Factory Pre-lubed for MX Mechanical Keyboard (110PCS) Review (2026)

Who this switch set is built for

The Jupiter Red set suits builders and typists who want a smooth linear switch straight out of the bag without spending an evening hand-lubing stems and springs. At 45gf actuation force, these switches favor light, fast keystrokes, which makes them a comfortable pick for long typing sessions and for gaming where quick, repeated presses matter. With 110 pieces in the set, there is enough for a full size keyboard with a numpad and still a handful of spares left over for a smaller board or future repairs. Anyone who bottoms out hard or has a heavier typing style may find the light springs less forgiving, since accidental presses become more likely as actuation force drops.

Construction and specs explained

Jupiter Red switches use a polycarbonate top housing paired with a nylon bottom housing, a combination chosen for a slightly deeper, less hollow sound than an all-polycarbonate build. The stem is POM, a low-friction plastic that keeps keystrokes gliding smoothly rather than scratchy, and a single-stage stainless steel spring provides consistent resistance through the full 4.00mm of travel with actuation at 2.00mm. Every switch ships factory pre-lubed, so the lubrication is applied at the factory rather than left for the buyer to do by hand, and a gold alloy contact point along with an LED light diffuser keeps the switches compatible with RGB boards. The 5-pin design adds two extra plastic pins beyond the standard 3-pin mount, which helps the switch sit more securely in a plate or hot-swap socket.

Living with these switches day to day

Because these switches arrive pre-lubed, most builders can install them straight into a hot-swap board and start typing without any extra prep work, which saves real time compared with switches that need manual lubrication before use. The factory lube job is even and functional, though it will not match the precision of a careful hand-lubing pass, so enthusiasts chasing the smoothest possible feel may still want to relube by hand. During normal use the light 45gf force keeps fingers from tiring over long sessions, but it also means resting fingers lightly on keys can trigger accidental presses more easily than a firmer switch would. Keep spare switches from the 110-count set on hand in case one develops a scratch or stops registering, since swapping a single switch on a hot-swap board takes only a switch puller and a few seconds.

Trade-offs and how it compares

In the site's linear switches guide, Jupiter Red ranks second of eight behind the Gateron Milky Yellow Pro V2, which scores 8.8 with a firmer 50gf spring and a similar pre-lubed factory finish. The two switches share a lot of DNA as Gateron products, but the Milky Yellow's slightly heavier spring reduces accidental presses for typists who rest their fingers on the keys, while Jupiter Red's lighter 45gf pull suits faster, lighter typing and gaming. Further down the guide, JWICK Red switches at 62g offer a firmer, budget-friendly alternative for anyone who wants to avoid the light-spring trade-off entirely. If a whisper-light keystroke is the priority, Jupiter Red delivers it well, but if accidental key presses are a concern, the Milky Yellow Pro V2's extra 5gf of resistance is worth the small step up.

Verdict and who should pick something else

Jupiter Red earns its high ranking by combining a smooth factory pre-lube, a generous 110-piece count, and a light 45gf pull that suits fast typists and gamers who do not bottom out heavily. It is a sensible default for anyone building or upgrading a hot-swap keyboard who wants good performance without extra lubing work. Typists with a heavier touch, or anyone who has struggled with accidental key presses on light linear switches before, should look at the top-ranked Milky Yellow Pro V2 or a firmer switch like JWICK Red instead. For a smooth, ready-to-install linear switch in full size quantity, Jupiter Red remains a strong second-place choice in this guide.
