Under the flags of the K series, the Swiss brand Logitech produces a variety of keyboards that, according to one criteria or another, are not suitable for the Logitech G, MK, MX and Folio lines. Accordingly, you can find literally anything here ― from simple office keyboards to specialized models for televisions and tablets.

The locomotive of this series is the Logitech Keyboard K120 office legend. Like many other representatives of the K series, this model is an excellent example of a moderately convenient and reliable tool that will serve faithfully for more than one year. If its capabilities are not enough, there are similar membrane models in the range of the K series, which differ in connection options (USB or radio), the type of keys (classic or island), the presence of water protection and additional functions like a handstand or multimedia keys. For a wireless model, stores can ask for about $ 50, while the option with a USB cable will cost a maximum of $ 25.


On the other side of the barricades are compact and ultra-compact keyboards a la K380, K480 or K580, which are usually bought for printing on the go, using a tablet or smartphone as a docking station. Most often, these are quite expensive devices with high-quality Bluetooth receivers, instant connection, good battery life and a holder for a smartphone or tablet. Usually they differ in the design of the keys (membrane or scissor) and some specialized chips. For example, the K480 was specially made heavy so that it would not outweigh when connecting a large and heavy tablet. And the K580 has a separate Easy Switch button for quick switching between several connected devices.

Special mention should be made of the TV keyboards of the K series, which are equipped with a built-in touchpad to simplify navigation through the TV menu. Their design, layout and functionality resemble the tablet keyboards described above, with the difference that the emphasis is placed on managing multimedia functions instead of printing quality or speed.
