ABSTRACT:
A mouse scroll wheel module includes a retention part, a holding part sitting on the retention part to swing from front to back and from left to right, a revolving part installed on the holding part, a mechanical revolving encoder to receive output of encoded electronic signals as the revolving part rotates, and a circuit board for controlling a middle switch and right and left switches, fixed between the retention part and the holding part. The holding part comprises a swing base and a holder that supports the swing base. With the support of the holding part, the scroll wheel of the revolving part is able to rotate and swing laterally, making the currently selected window on the screen to scroll in four directions: up, down, left or right.
