Gateron - KS-33 3.0 Low Profile Switch V2 Black Bottom

Low-profile, silent mechanical switches for compact keyboards

GATERON KS-33 Low Profile Silent 3.0 mechanical switches are designed for compact mechanical keyboards that require a slim switch design and quieter typing operation. Thanks to their linear mechanism and carefully selected housing materials, they offer different actuation force variants, allowing the typing feel to be tailored to individual preferences.

The KS-33 Silent 3.0 series features a POM stem, a transparent polycarbonate (PC) top housing, and a black nylon bottom housing. Each switch is factory-lubricated, ensuring smooth key movement and stable operation. The 5-pin design and SMD LED backlighting support make these switches suitable for compatible keyboard PCBs.
