4.2 Linear Red Switches
The keyboard is equipped with linear red mechanical switches. These switches are characterized by a smooth, consistent keystroke from top to bottom, requiring less force to actuate.

4.3 Full Anti-Ghosting
All 61 keys on this keyboard feature full anti-ghosting (N-key rollover). This ensures that every keypress is registered accurately, even when multiple keys are pressed simultaneously. This feature is crucial for fast-paced gaming and efficient typing, preventing missed inputs.

4.4 Backlit PBT Keycaps
The keyboard is equipped with durable double-injection PBT keycaps. PBT material offers superior resistance to wear, fading, and shine compared to ABS keycaps. The double-injection process ensures that the legends are part of the keycap structure, preventing them from wearing off. The keycaps are designed to allow the RGB backlight to shine through, enhancing visibility and aesthetics.
