❓ Frequently Asked Questions
What makes the 1.0mm actuation special?▼
The 1.0mm pre‑travel is significantly shorter than standard linear switches (typically 2.0mm). This means the switch registers your keystroke almost instantly — perfect for competitive gaming and rapid typing where every millisecond counts.
Is 37g too light for typing?▼
Not at all. The 37g force is designed to reduce finger fatigue while still providing enough resistance to avoid accidental presses. Many users find it ideal for long typing sessions, gaming, and office work.
Do I need to lube these switches?▼
No. They come factory pre‑lubricated with a light oil on the stem rails and spring. The full POM construction also provides inherent self‑lubrication, so they are smooth and scratch‑free out of the box.
Are they compatible with 3‑pin PCBs?▼
Yes, these are 5‑pin switches. The two plastic positioning pins can be clipped off to fit 3‑pin PCBs without any issue.
How durable is the BOX structure?▼
The BOX design seals the internal contact leaf from dust and moisture, offering IP54‑like protection. Combined with gold‑plated contacts, it's rated for 50 million keystrokes — reliable for years of heavy use.
What's the return policy if I don't like the feel?▼
We offer a 30‑day no‑questions‑asked return policy. If the switches don't meet your expectations, simply contact our support team for a full refund or exchange.
