Key Features & Benefits

All-PC Construction

Full polycarbonate housing and stem provide superior clarity in RGB lighting, consistent sound profile, and enhanced durability. PC material offers excellent smoothness and a clean, crisp typing experience.

Factory Lubrication

Pre-lubed from the factory for instant premium performance. Save time and enjoy buttery-smooth keystrokes right out of the box—no manual lubing required.

Gold-Plated Springs

Premium 20mm gold-plated springs resist corrosion and ensure consistent spring weight throughout the switch's lifespan. Longer springs provide smoother return action and reduce spring ping.

Linear Performance

Smooth, consistent keystrokes with no tactile bump or click. Perfect for gaming where rapid actuation is crucial, or for typing enthusiasts who prefer a fluid, uninterrupted keystroke.

Multiple Weight Options

Choose from 37g (ultra-light), 55g (medium), or 62g (medium-heavy) to match your typing preference. Lighter weights reduce finger fatigue, while heavier weights provide more deliberate control.

5-Pin PCB Mount

Full 5-pin design ensures stable mounting and reduces wobble. Compatible with both hot-swap sockets and traditional solder PCBs. Simply clip the extra pins for 3-pin plate-mount keyboards.

Recommended Use Cases

37g - Ultra-Light: Ideal for speed typists, those with lighter key press preferences, or users looking to reduce finger fatigue during extended typing sessions. Extremely fast actuation for competitive gaming.

55g - Medium: The versatile all-rounder perfect for both gaming and typing. Balanced weight provides good tactile feedback without being too heavy or too light. Great for first-time linear switch users.

62g - Medium-Heavy: Best for deliberate typists who want more resistance and control. Reduces accidental key presses and provides a more substantial feel. Excellent for precision gaming and professional typing work.
