    The renowned switch designer Gazzew has worked in tandem with Outemu to produce perhaps his best switch yet: the Boba U4. Tactile, yet silent, this is an ideal switch for those who like to feel their switches actuate while not being a nuisance to their (or others') ears.

    What's in a name? U4 is short for Euphoria, which you'll for sure experience on these switches. If you're one to lube your switches - be sure to give these a try unlubed first, as I've been told they feel great fresh from the factory already. Enjoy!


    You can purchase these switches per 10, or in a convenient bundle. Purchasing switches in a bundle will be more affordable than buying them per 10:

    • 200 - for multiple keyboards;
    • 110 - for a full size keyboard;
    • 90 - for a tenkeyless keyboard;
    • 70 - for a 65% keyboard;
    • 50 - for a 40% keyboard (like the Kyria or Planck).

    Tech specs

    • Available in two weights: 62g and 68g;
    • Available in two switch tops: Boba, which matches the base housing, and Clear, which is more suited to keyboard builds featuring per-key RGB switches;
    • U4 Silent Tactile "D" stem: no pretravel, all bump, no post bump travel;
    • Very smooth feel, removing the need to lube the switch (if you insist, do try them without lube first);
    • Reduced leaf ping due to metal composition and newly designed base along with factory lubed spring bottoms and leafs (the slide rails are not lubed);
    • Five pin housing allows for more stable seating on PCBs;
    • Universal base with RGB slot, compatible with all LED styles;
    • Compatible with hotswap sockets such as 7305 Mill Max sockets, Kailh and Gateron MX sockets, and Outemu-only sockets;
    • Korean stainless steel springs for a long lasting, consistent weight.

    For Gazzew silent switches, there should be no noticeable difference in sound and feel between the color matched top and the clear top, as the down- and upstrokes will be dampened. In non-silent switches this is different, where the down- and upstrokes would make a different sound when typing.
