Yilima QS-500 Mechanical Numeric Keyboard (22-Key Layout, Wired USB Plug-and-Play, Ergonomic Mechanical Switches, LED Backlit, White, QS-500)

The Yilima QS-500 Mechanical Numeric Keyboard is a specialized, compact external keypad engineered to streamline data entry, accounting workflows, financial calculations, and complex spreadsheets. Featuring a robust 22-key layout that expands beyond a traditional numpad, it includes vital productivity keys like Backspace, ESC, and Tab, putting complete mathematical control directly alongside your compact laptop or tenkeyless (TKL) desktop keyboard.

Built with high-quality mechanical key switches, the QS-500 delivers a crisp, satisfying tactile feel with every single keystroke. This physical response helps eliminate mistypes and reduces finger strain during long hours of repetitive data logging. The premium ABS double-shot keycaps are durable enough to withstand millions of continuous presses without fading. Illuminated by bright, subtle LED backlighting, the keypad ensures complete layout visibility in low-light office environments or night shift conditions. Operating on a simple wired USB connection, it is completely plug-and-play with no drivers or software installations needed, making it an excellent computing companion for accountancy professionals, Excel wizards, and data analysts on the move.
