# JKDK XCJZ - Butterfly Silent Linear Switches

**Experience ultra-smooth and silent typing with the Butterfly Silent Linear Switch—designed for mechanical keyboard users who prefer soft presses and quiet performance.**  
Developed by XCJZ and JDK, this upgraded version of the Dopamine switch delivers clean linear movement with excellent sound dampening, thanks to its TPU soft rubber bottom-out structure and enhanced lubrication.

Manufactured by Outemu, each switch comes pre-lubed with a semi-fluid grease for smoother keystrokes and reduced friction. Its 20mm single-stage extended spring ensures a soft rebound and light feel, ideal for quiet workspaces or night typing sessions.
