In any competitive battle, the tiniest fractions of a second matter. That’s why we’ve designed a mouse switch that actuates at the speed of light. The Razer™ Optical Mouse Switch is a stark upgrade from the traditional mechanical mouse switches used in gaming, with instant actuation and unparalleled durability to deliver a competitive edge.


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.


As no mechanical contact is needed for the transmission of electrical signals, the Razer™ Optical Mouse Switch is less prone to wear and tear from extensive usage. This allows an industry-leading durability of up to 70 million clicks—40% more than the previous best.
