AFLION Iceberg is a smooth linear switch with minimal stem wobble; thanks to the dust-proof stem and factory lube, ensuring no extra work is needed to bring them to a usable state. It also has less spring and leaf ping than competing switches. Iceberg uses an extended dual-rate (two-stage) spring, ensuring flawless activation and satisfying feel every time. The actual actuation forces are slightly heavier than listed because of the spring.
