Backed by four generations of development, rigorous testing, and validation, discover how our most advanced switches lead the industry by achieving a new standard for precision and durability.

When a click is made, an optical mouse switch opens its shutter to allow an infrared light beam to pass through, which sends an electrical signal to your computer. As actuation is achieved at the speed of light, this ensures the fastest response time for peak competitive performance.

With the lowest click latency around, our innovative switch design provides a level of response that’s second to none.

Fine-tuned with pro player and community feedback, make every click count with switches that are more reliable, responsive, and tactile than ever before.

By using light-based actuation instead of physical contact points for click detection, optical mouse switches completely bypass the issue of mechanical wear and tear, ensuring exceptional durability and long-term performance.
