Desktop computer switch replaces the old computer button, allowing for convenient power restarting and control of external USB components on the desktop, enhancing both accessibility and security. The RGB dynamic lighting effect is driven by 4 RGB LEDs through the MCU, showcasing a special effect at startup before transitioning to a dynamic spectrum cycle, creating a harmonious look with water-cooled chassis and RGB peripherals. The button allows for powering on and restarting, and the RGB lights will turn off once the system is powered on or off. Featuring dual USB 2.0 interfaces that are connected directly to the motherboard, it does not occupy the rear panel interface and can be used for peripherals such as USB drives, keyboards, mice, and for charging mobile devices. The adhesive base allows for easy installation on any desktop surface, making it ideal for home users or internet cafes looking to upgrade.
