Kailh Deep Sea Silent Pro Box Switch

Kailh Deep Sea Silent Pro Box Mechanical Keyboard Switches

The Kailh Deep Sea Silent Pro Box Switch series is designed for mechanical keyboard enthusiasts who want a quieter typing experience without giving up the feel of a mechanical switch. Featuring a distinctive transparent blue protective cover, dark blue nylon base, factory lubrication, and integrated noise-reduction cushioning, these switches combine functional design with a striking deep-sea appearance.

Available in two distinct variants, the Islet Linear offers smooth keystrokes, while the Whale Tactile provides a noticeable tactile bump. Choose the version that best matches your typing preferences.

Silent Typing with Noise-Reduction Cushioning

The Deep Sea Silent Pro Box switches use a cushioning structure designed to reduce the noise produced during key presses and release. This makes them suitable for offices, shared workspaces, libraries, and home setups where quieter typing is preferred.

Although designed for silent operation, the actual sound profile can vary depending on the keyboard case, plate, keycaps, mounting system, and typing technique.
