Ducky One 3 Classic SF Keyboard Gaming USB US English Black White

The Ducky One 3 Classic SF is a compact wired gaming keyboard with a 67-key layout, RGB backlighting and USB Type-C detachable cable. Built with a dual-layer PCB, hot-swappable Kailh sockets and a low-profile case, this keyboard is engineered for stability, reliable signal transmission and long-term use. Keycaps are true PBT with double-shot legends and a frosted finish for resistance to shine and wear. Multi-layer internal padding and an EVA foam layer under the PCB improve acoustic performance and reduce unwanted noise.

Advantages

True PBT double-shot keycaps ensure legends do not fade and provide a durable, stain- and shine-resistant surface. Hot-swap Kailh sockets allow easy installation and replacement of mechanical switches without soldering. Dual-layer PCB enhances signal stability and longevity while supporting N-key rollover or 6-key rollover. The lowered case height and optimized weight distribution keep the keyboard stable during intense use, and three tilt angles via two-step feet accommodate different typing preferences. RGB backlighting offers customizable lighting effects at adjustable brightness and speed.

Suitable for

• Compact gaming setups requiring a 67-key (SF) layout
• Users who want to test or swap mechanical switches frequently (hot-swap)
• Typing and gaming where durable keycaps and stable mounting are important
• Users who prefer customizable RGB lighting and adjustable keyboard tilt

Change lighting effects, brightness and speed using the keyboard’s built-in controls. Adjust typing angle by extending the two-step feet to the desired position.

Recommendations

For prolonged keycap life, avoid exposing the keycaps to direct sunlight and clean them with a soft, dry cloth. When swapping switches, power off the host device to avoid accidental inputs. Use the EVA foam and padding features together with appropriate switch choice to tune acoustic response and minimize unwanted noise.
