Razer Optical Mouse Switches Gen-4

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 you click, the switch’s shutter clears the path for an infrared light beam to pass through—instantly triggering 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.

At the heart of our Gen-4 design is a finely tuned 0.25 mm actuation distance, engineered for the lowest click latency in its class. This precise threshold offers the perfect balance between pre-travel and post-travel^*, creating a crisp, responsive click feel.

* Pretravel describes how far the switch moves before your click actuates. Posttravel describes how much it moves after the click has activated.

ACTUATION FORCE CURVE (TACTILE RESPONSE)

With an industry‑leading click ratio and instantly responsive tactile feedback, every press registers precisely as intended—letting players react with confidence and avoid missed or accidental inputs.

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.
