Abstract
A magnetic damping top-speed optical wheel which includes a PCBA board; a middle button, a right swing button, and a left swing button are arranged on the PCBA board; a bracket is arranged on a surface of the PCBA board; an optical sensing assembly is arranged inside the bracket and electrically connected with the PCBA board. A pressing portion is arranged on the bracket between the left swing button and the right swing button. The pressing portion is parallel to the left swing button and the right swing button, such that vertically pressing the wheel would only trigger the middle button but the left swing button or the right swing button.
