Features: All parts are perfectly matched, and the claw spring sleeve is perfectly matched to the original shell's micro-movement opening, which is more stable and more stable. During the clicking process of the mouse, the micro-movement is force up and down instead of left and right. When the mouse shell is installed, under the action of the lower PCB and the upper button column, you will not feel the micro-movement during use at all. In the case of "shaking", it is crucial to know the direction of the force. The principle of the claw spring sleeve can be referred to the hot-swappable shaft seat of the mechanical keyboard. It is the elastic conductor material to grasp the fretting feet. Even if the fretting feet are replaced many times, no matter whether the feet are thick or thin, there will be no problem of poor contact. The reason why the claw spring socket shakes is that the elastic material grabs the fretting foot, and the elastic deformation is inevitable, but this is also the foundation to ensure that the socket can continue to conduct electricity after many times or even hundreds of times of unplugging and plugging. This key board is remade, no need to change the original pcb, just a screwdriver can be done, unscrew the screw to remove the original key board, plug in the cable and screw back the screw, and use it immediately. There is no need for a soldering iron to replace the micro-motion. brand new and high quality Package Includes: 1 x Logitech GPX hot-swap micro-motion motherboard Specifications: Type: for Logitech GPX hot-swap micro-motion motherboard Material: Plastic Quantity: 1PC Color: Purple Compatible models: for Logitech G Pro X Superligt Gaming Mouse note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
