[0002] Existing mechanical electric heaters and other electrical appliances use a dial switch structure to adjust the gear position. However, the dial switch structure lacks clear gear position feedback when adjusting the gear position, making it difficult for users to intuitively judge the current temperature setting. In addition, due to the lack of precise gear position limits, gear position jumps or inaccurate positioning problems are prone to occur, affecting user experience and device performance. Summary of the invention

[0003] In view of this, the present invention provides a switch structure and an electrical device to solve the problem that the switch structure lacks clear gear feedback and is prone to gear jumps or inaccurate positioning.

[0004] In a first aspect, the present invention provides a switch structure, comprising:

When the gear adjustment part moves, the gear of the to-be-adjusted structure of the electrical equipment can be adjusted through the switch. During the movement of the operating component, when the protrusion cooperates with different limit grooves, the protrusion will generate slight elastic force and friction when switching between different limit grooves, which increases the user's sliding feel, provides the user with clear gear feedback, and improves the user experience; at the same time, the limit groove can also limit the protrusion to achieve precise gear limiting, avoid gear jump or inaccurate positioning problems, and ensure the user experience and equipment performance.

[0010] In an optional embodiment, at least three limiting protrusions are protruding from the groove wall of the first sliding groove, and the at least three limiting protrusions are arranged at intervals along the sliding direction and form at least two limiting grooves with the groove wall of the first sliding groove.

During the movement of the operating component 3, when the protrusion 111 is limited with different limiting grooves 311, a slight elastic force and friction will be generated when the protrusion 111 switches between different limiting grooves 311, which increases the user's sliding feel, provides the user with clear gear feedback, and improves the user's experience; at the same time, the limiting groove 311 can also limit the protrusion 111, realize the precise limit of the gear, avoid the problem of gear jump or inaccurate positioning, and ensure the user's experience and the performance of the device.
