Description

Technical Field

[0002] In the prior art, in the field of control devices, especially in game controllers, robot control systems and high-precision instruments, Hall rocker arms have become a mainstream and advanced control component. Based on the Hall effect principle, a Hall rocker arm realizes precise detection and conversion of control signals by sensing magnetic field changes. A Hall rocker arm mainly consists of key components such as a rocker arm body, a Hall element, a magnet and a circuit board. The rocker arm body serves as the interface for user operation. By the movement of the user, the relative position between the magnet and the Hall element is changed, thereby causing a magnetic field change. The Hall element, as the core sensor, can accurately capture this magnetic field change and convert it into an electrical signal. The magnet is responsible for generating a stable magnetic field to ensure the stable operation of the Hall element. The circuit board is responsible for further processing the electrical signal output by the Hall element and finally converting it into a recognizable control instruction. With the development of technology, higher requirements are also imposed on Hall rocker arms. Summary of the Invention
