Razer Optical Mouse Switch
Every click you make actuates at the speed of light. The Razer™ Optical Mouse Switch utilizes an infrared light beam to register a click, resulting in an industry-leading response time of 0.2 milliseconds. Its instant actuation eliminates debounce and unintended clicks, giving you complete control in execution.
