Razer Optical Mouse Switch | Fastest Mouse Actuation

When the difference between victory and defeat can be fractions of a second, the speed, reliability, and durability of Razer™ Optical Mouse Switches will always come in clutch. With a blistering 0.2ms response time, zero double-clicking issues, and a vastly improved 90-million click lifespan, we continue to rise the bar by producing the best mouse switches in the business—the result of three switch generations of development, testing, and validating.

When a click is made, the Razer™ Optical Mouse Switch opens its shutter to allow an infrared light beam to pass through. This is how an electrical signal is sent to your computer. Actuation is achieved at the speed of light, generating the fastest response time in gaming at 0.2 milliseconds — 3 times faster than traditional mechanical switches.

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

Traditional mechanical switches send electrical signals via metallic contact. When these contacts strike each other, they create a residual bouncing effect that can result in multiple signals. A debounce delay software is used to overcome this bouncing effect so that only a single click is registered. With the Razer™ Optical Mouse Switch, no physical contact is needed to send an electrical signal, eliminating the need for a debounce delay. Any click is actuated instantly with no unintended clicks.

With no mechanical contact needed for the transmission of electrical signals, Razer™ Optical Mouse Switches are far less prone to wear and tear, allowing for an industry-leading durability of up to 90 million clicks.
