According to information from the China National Intellectual Property Administration, Beijing ABB Low Voltage Electrical Appliance Co., Ltd. has filed a patent titled “Electrical Device,” with publication number CN121366837A, submitted in July 2024.

The patent abstract describes an electrical device composed of multiple components, including a disk assembly, a handle, and a connecting rod. The disk assembly consists of an upper disk, a middle disk, and a lower disk, all rotating around the same axis. The handle can switch between an open position and a closed position. The connecting rod is connected at one end to the handle, while the other end is inserted into a slot formed by the three rotating disks.

This structural design shortens the kinematic chain of the device, resulting in a simpler overall architecture while improving operational stability and reliability. It reduces mechanical complexity and enhances consistency in switching performance.

The invention reflects ongoing efforts in low-voltage electrical equipment design to optimize structural efficiency and improve system robustness, supporting more reliable performance in industrial applications.
