The Jarvis JJ Silent Linear Switch is a custom mechanical switch designed by JamesDonkey and What The JARVIS, combining whisper-quiet performance with smooth, responsive actuation.
Built for those who prefer a soft touch and minimal sound, the switch features a 47g actuation force and a total travel of 4.0mm. Its 18mm extended spring provides responsive rebound and consistent feel, while the dual-color POM + silicone stem delivers a clean linear motion without scratchiness.

Each switch is factory-lubed with Japan-imported PTFE-based PR03 lubricant, ensuring long-lasting smoothness and stable sound performance. Designed for 3-pin MX-compatible hot-swap boards, it's ideal for custom mechanical keyboard builds focused on silent operation and tactile control.
