Ragna is a linear switch characterized by its crisp clicking sound.
Compared to the magnetic key switches that have become popular recently, these have a slightly deeper stroke length of 3.7 mm, giving them a feel that’s characteristic of mechanical keyboards.
Although nothing has been announced yet, I wonder if the theme color will be green.

In any case, I’m looking forward to seeing how it turns out.
Let’s wait for further information.
