Know before you buy
Yes, these are 3-pin switches, which means they are fully compatible with both 3-pin and 5-pin hot-swappable mechanical keyboards.
The Jarvis JJ switches feature a dual-color POM and silicone stem designed specifically for silent operation. The silicone dampening significantly reduces the 'clack' sound, making them much quieter than standard linear switches.
No, these switches come pre-lubricated from the factory using high-quality PR03 lubricant. They are ready to install right out of the box for a smooth, consistent feel.
A 47g actuation force is considered a medium-light weight. It provides enough resistance to prevent accidental keypresses while remaining light enough to minimize finger fatigue during long typing or gaming sessions.
The 18mm extended spring provides a snappier, more responsive rebound compared to standard-length springs. This helps the switch return to its original position faster, which many users find improves typing speed and consistency.
Yes, these switches feature a standard MX-style stem, making them compatible with the vast majority of aftermarket mechanical keyboard keycaps.
