💬 What Users Say
⭐⭐⭐⭐⭐
"The double dust protection is a lifesaver. I eat at my desk, and my old switches would get crunchy after a few months. These stay smooth. 40g is perfect for fast typing."
— @DeskSnacker
⭐⭐⭐⭐⭐
"Coming from Cherry MX Reds, these feel even smoother and more responsive. The gold spring gives a snappy rebound that helps in FPS games. Highly recommend."

❓ Frequently Asked Questions
What's the difference between BOX V2 Red and standard BOX Red?▼
BOX V2 Red features an extended gold‑plated spring for snappier rebound and better corrosion resistance, plus improved dust wall design for even better protection. The V2 also has refined factory lubrication for smoother out‑of‑box feel.
Is the switch pre‑lubed?▼
Yes. Every Box V2 Red switch comes factory pre‑lubed on rails, spring, and stem. You can use them immediately without any additional work.
How does the double dust‑proof structure work?▼
There's a physical dust wall around the stem that blocks large particles, combined with the sealed BOX housing that prevents fine dust and moisture from reaching the internal contacts. This dual layer ensures long‑term reliability.
Can I use these on a 3‑pin PCB?▼
Yes. The switch has 5 pins, but the two plastic positioning pins can be clipped off with flush cutters to fit 3‑pin PCBs without any issue.
Is the gold‑plated spring really beneficial?▼
Absolutely. Gold plating prevents rust and corrosion, ensuring consistent spring performance over years. It also provides a slightly crisper, more consistent rebound compared to standard steel springs.
How does 40gf feel for heavy typists?▼
40gf is considered light – similar to Cherry MX Red. Heavy typists may find it very comfortable for long sessions, reducing finger fatigue. If you prefer more resistance, consider BOX V2 Black (60gf).
