The Majestouch Convertible series, same as Majestouch series, is a series of mechanical keyboards equipped with CHERRY MX switches for each key. 4 types of CHERRY MX switches are used with different spring strength and depression feelings. In the old model, it was necessary to press the recessed switch with the tip of a pen or press multiple keys to perform pairing and switching devices. Convertible 3 allows you to make those settings with a single touch by consolidating them into dedicated Bluetooth buttons. In addition, to prevent accidental button presses, we have adopted a highly usable frame design with special consideration to placement and installation location. With Bluetooth (version 5.1) connection, not only PCs but also various devices such as smartphones and tablets up to 4 devices can be registered, and you can switch between them with one touch. With the Convertible 3, you can change the key code by operating the DIP switch on the back of the main unit. In addition to changing the common functions of switches (1) to (3) for Convertible series, you can now choose from 4 patterns for the Fn key layout by combining the ON/OFF of switches (4) and (5). In addition, a simple Mac mode function has been added to switch (6), and a power saving mode disable function has been added to switch (7). The simple Mac mode functions are pre-engraved on the front of the keys. A key puller and removeable cable are included.
