Key Mechanical Numeric Keypad Features & Considerations
Design
Normally the keyboard design is the first factor we will consider when ordering one thing. Even it is at the lowest price, if we do not like the design , we probably will not take it home.
As a member of Kzzi k series, K20 adopts kzzi classic design that owns 19 keys with a knob. The knob can be used to adjust the kyeboard rgb or your PC volume. If you already hava a keyboard K68 or K75 series, and you are also looking for a glorious numpad. Kzzi K20 would be your choice.

Build Quality
From low-budget to mid-budget to high-end models, mechanical keyboard numpads cover a wide range of choices for different users. At the entry level, we will often find plastic numpads that are lightweight, durable, and perfect for everyday data entry or casual office work.
Moving into the mid-range, many numpads come with better build quality, such as reinforced frames, mechanical switches for a more satisfying typing experience, and even wireless connectivity options.
At the premium level, we can find high-end numpad crafted with aluminum frames, hot-swappable switches, programmable keys, and customizable RGB lighting—ideal for professionals and enthusiasts who want both durability and style.
As a budget-friendly numpad numeric keypad, the KZZI K20 stands out with its sturdy plastic build. It delivers reliable performance without the premium price tag, making it a great entry point for users who want to experience the efficiency of a dedicated numpad without overspending.
Structure
The numpad keyboard structure and mounting style play a crucial role in determining both the typing feel and typing sound. A numpad’s internal filling material, including the type of mounting system used for the switches, significantly impacts how each key responds under pressure, how comfortable typing feels, and how the sound resonates with each keystroke.
The Kzzi K20 numpad adopts a top mount structure, which is designed to enhance the overall consistency of the typing experience. In a top-mount design, the switches are mounted directly onto the top plate of the keyboard, allowing for a more stable, rigid feel when typing. This structure helps to reduce flex and provides a more consistent and predictable typing response across all keys. For users, this means less wobble and a more satisfying feedback with every press.
Connectivity
Generally speaking, usb numpad is more stable when the wireless numeric keypad has higher demand for stable performance of 2.4G and bluetooth. If it is acceptable for us to connect keypad numpad with cable on the desk or there is enough port on the pc, then a wired usb numeric keypad might be a good choice.
But for someone like me, who want to keep the desk as clean as possible, it is necessary for me to get a wireless numeric keypad. So that there is no more cable round the working or gaming area.
Kzzi K20 supports 3 modes connection, including wired, 2.4g, and bluetooth. It will not occupy extra PC port, offering much convenience for laptop user. The mode switch button is near the usb port, which is easy to switch the wireless keyboard numeric keypad between 3 modes.
Switch
In the last blog, we talked about the difference between mechanical numpad and membrane keyboard. Maybe the membrane can offer a quieter typing feeling. But there is a one thing, the switch of membrane keyboard is soldered on the PCB, if one is broken, it is hard for us to repair or replace the switch. While for mechanical numpad, the hot-swappable feature enable us to replace the switches we like.
Kzzi K20 is a hot-swappable numpad. With hot-swappable sockets, we can easily change switches without any soldering skills. If one switch wears out or we simply want a different typing feel—such as tactile, linear, or clicky—we can swap them in seconds. This not only extends the overall lifespan of numpad, but also makes it highly customizable to match your personal typing preference.
Keycap
The most common keycap materials used on numpads are ABS and PBT.
ABS (Acrylonitrile Butadiene Styrene) keycaps are lightweight, smooth, and generally more affordable. They are often found on budget-friendly numpads, but they may develop shine over time with heavy use.
On the other hand, PBT (Polybutylene Terephthalate) keycaps are thicker, more durable, and resistant to wear, making them a popular choice for mid-range and premium mechanical numpads. PBT keycaps also tend to have a textured surface that provides a more comfortable and long-lasting typing experience.
K20 wireless numeric keypad for laptop is equipped with PBT keycaps, and the double-shot keycap process makes the legend on the keycap will not fade. The legends are molded into the keycap rather than printed on the surface. Even years of heavy use, this K20 numberpad keyboard still remains a reliable choice for students, professionals, and anyone who relies on a numeric keypad for daily tasks.
Backlight
A custom numpad with backlight is not only stylish but also highly practical.
The illuminated keys make it easier to work in low-light environments, whether you are entering data late at night, working in a dim office, or gaming in a dark setup. Many best buy numeric keypads offer adjustable brightness levels and even RGB backlighting, allowing users to personalize their typing experience.

A customizable programmable numpad is not just an accessory—it’s a powerful tool to enhance both work and play.
