The FJ 400 switch is one of the HMX Film switches. Among the film Switch series, FJ400 is the one with a medium clack sound. It also has a T series stem, but the P2 bottom housing which you see on Cloud switches, generates a clacky but full bottom-out sound. Like the Classic and KD200 switches, FJ400 switches are also made using HMX's newest stem and bottom housing molds. The new molds come with a refined typing feel.
