Comments on MMD Vivian switches | Comments on HMX Twilight switches |
MMD Vivian linear switch delivers a satisfying thocky sound profile. The switch features a modified UPE stem that enhances durability. Its top housing is constructed from PA12, while the bottom housing uses modified PUM – Lume Keebs. | The HMX Twilight linear switch can be seen as a Cheese switch with a longer travel. It has the same materials as the Cheese switches, but the total travel is now around 3.85mm. The change in travel distance makes the Twilight switches a tiny bit quieter and lower-pitched than Cheese, but they are still the OG clacky HMX switch you are familiar with. |
