Traditional toggle switch designs typically employ a single or double slide structure, which is simple and easy to implement. However, with the increasing functional requirements of electronic equipment and the increasing complexity of circuit design, higher requirements are placed on the performance and reliability of toggle switches. During operation, traditional toggle switches often suffer from problems such as inflexible operation and unstable contact due to the limitations of the slide structure. Especially in applications that require multi-state switching, a single slide structure cannot meet the requirements of complex circuits. In addition, traditional toggle switches also have certain limitations in terms of waterproofing and dustproofing, making them difficult to adapt to harsh working environments. Utility Model Content

[0005] Compared with the existing technology, the beneficial effect of the above structure is that: by designing two slide grooves with upper and lower offsets, combined with the structure of the conductive column and the compression spring, the toggle switch can achieve multi-state switching, thereby adapting to the needs of different circuits and control systems. At the same time, the compression spring and the conductive column structure in the slide groove ensure stable contact between the conductive column and the static contact piece, thereby improving the reliability and stability of the switch. By arranging a waterproof cover above the positioning seat and setting a pressure plate on the waterproof cover, the waterproof cover is tightly fixed to the bottom shell, thereby effectively improving the waterproof and dustproof performance of the switch, enabling the switch to work normally in harsh environments such as humidity and dust, and extending its service life.
