Detailed Embodiment

[0019] The present utility model will be further described in detail below in conjunction with the drawings and the detailed embodiment.

[0020] In this embodiment, referring to Figures 1-5 , a DIP switch convenient for cleaning implemented specifically includes a housing 1, a push button 2 installed in the housing 1, a guide piece 3 fixed to the push button 2, and pins 4 respectively fixed on both sides of the housing 1. Detachable transparent plates 6 are installed on both sides of the housing 1 through card slots 5, and the transparent plates 6 are provided with buckles 7 that cooperate with the card slots 5. An opening 14 is provided on the housing. Usually, the transparent plate 6 is firmly fixed on the housing 1 through the cooperation of the buckle 7 and the card slot 5, and the internal parts can be directly observed through the transparent plate 6 at the opening 14 to check whether they fall off or need to be cleaned. When it is necessary to clean the inside of the DIP switch, the buckle 7 is disengaged from the card slot 5, and the transparent plate 6 can be taken out, so as to clean the dust and other impurities on the internal parts through the opening 14. Thus, the practicability and convenience of the DIP switch are improved.

[0021] Furthermore, the transparent plates 6 on both sides enable tools such as air guns to blow gas into the inside of the DIP switch from one side, and impurities are discharged through the other side. This speeds up the cleaning speed and improves work efficiency.

[0022] Furthermore, the transparent plate 6 is made of a transparent plastic material with toughness and high temperature resistance, so that the transparent plate 6 not only has excellent transparency, facilitating the observation of the internal parts, but also its toughness and high temperature resistance ensure that the transparent plate 6 can maintain stable performance in a high temperature environment and is not easily deformed or damaged.

[0023] Furthermore, the housing 1 and the buckle 7 are respectively provided with a limiting groove 8 and a limiting block 9 for mutual cooperation. Through the cooperation of the limiting groove 8 and the limiting block 9, the transparent plate 6 has higher stability and firmness when fixed to the housing 1. During the installation process, only need to align the limiting block 9 with the limiting groove 8 on the housing 1, and then insert the transparent plate 6 into the housing 1 to complete the installation of the transparent plate 6. This design not only improves the installation efficiency, but also reduces the possibility of deformation or fracture of the buckle 7 caused by improper installation.

[0024] Furthermore, the limiting block 9 is T-shaped. By designing the limiting block 9 to be T-shaped, it can ensure a tighter fit between the limiting block 9 and the limiting groove 8, thereby further improving the stability between the transparent plate 6 and the housing 1. It can also limit the sliding or displacement of the transparent plate 6 on the housing 1, ensuring that the transparent plate 6 always remains in the correct position for facilitating the observation of the internal parts.

[0025] Furthermore, the housing 1 is provided with an outwardly inclined guiding structure 10. Through the guiding structure 10, when installing the transparent plate 6, it can push the buckle 7 to move outward, avoiding the situation that the buckle 7 slides inward or gets stuck during installation, resulting in the fracture of the buckle 7.

[0026] Furthermore, several positioning blocks 11 are provided on the transparent plate 6, and a sealing ring 12 is installed on the positioning blocks 11. When installing the transparent plate 6, it drives the positioning blocks 11 to insert into the openings 14 on the housing 1, and makes the sealing ring 12 cooperate with the openings 14, preventing dust and other impurities from entering the inside of the DIP switch, and further ensuring the stability and reliability of the DIP switch.

[0027] Furthermore, a pressing piece 13 for easy disassembly is provided on the outside of the buckle 7. By pressing the pressing piece 13, the buckle 7 is tilted outward, so that the buckle 7 is disengaged from the card slot 5, completing the rapid disassembly of the transparent plate 6, making the disassembly process more convenient and fast.

[0028] Advantages of the present utility model: Through the detachable transparent plates 6 on both sides of the housing 1, when it is necessary to clean the dust inside the DIP switch, only the transparent plates 6 need to be removed, and tools such as an air gun can be used to clean the internal dust. Moreover, through the cooperation of the buckle 7 and the slot 5, the installation of the transparent plate 6 is more stable and not easily detached. At the same time, the design of the transparent plate 6 also enables users to directly observe the position states of the push button 2 and the guide piece 3 without disassembling the DIP switch, facilitating timely replacement or adjustment. Thereby, the practicability and convenience of the DIP switch are improved.
