Hmx Jammy







I hope the Jammy switches bring you luck in the year to come! Jammy switches is HMX's another attempt to make a quieter, deeper, yet thocky switch. The P4 material used for the bottom housing is a softer nylon blend which is supposed to create a subtle and quieter bottom-out sound and a typing feel that is not so stiff; When combined with the POM stem and PA12 top housing, they create a switch that is smooth and great sounding. PA12 also allows for a transparent top housing which is aesthetic.
