With the U4 switches being universally loved, some of you wondered: what if the silent tactile switch wasn't silent? The U4 Thocky is the result: with a modified stem, these switches will provide a more familiar audible feedback, similar to other tactile switches. This switch is an all-black recolor of the U4T switch.

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!

Tech specs

• Available in two weights: 62g and 68g;
• U4 Silent Tactile "D" stem: no pretravel, all bump, no post bump travel;
  
• A familiar audible feedback due to a modified switch stem;
• 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 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.

Remarks

The version sold is slightly different from the picture. It has a circular cutout for a per-key LED instead of a rectangular slot. For most uses, this difference does not matter.
