The MMD Princess V4 linear switch is the newest iteration of the MMD Princess linear series. The current version has improved by adding a light diffuser to the top housing for a better RGB shine-through experience. The Princess V4 linear switches are also made with BSUN's newest molds to further increase its smoothness and decrease stem wobble. Other than that, when compared to Princess V2 switches, the bottom housing of the V4 is changed to PC material for an even more poppy and clacky sound profile.
