[0006] As a preferred solution of the utility model, the limit groove consists of a first oblique groove, a vertical groove, a V-shaped groove and a second oblique groove. The first oblique groove is connected to the vertical groove, the vertical groove is connected to the V-shaped groove, and the V-shaped groove is connected to the second oblique groove. When the limit hook enters the V-shaped groove from the first oblique groove and the vertical groove in turn, it is in a self-locking state, and when the limit hook returns to its original position from the V-shaped groove and the second oblique groove in turn, it is in an unlocked state.

[0007] As a preferred solution of the utility model, a plug hole is provided inside the chamber, one end of the limit hook is inserted into the plug hole, and the other end of the limit hook extends and bends upward.

[0008] As a preferred solution of the utility model, a positioning cone is provided inside the chamber, and the spring is sleeved inside the positioning cone.

[0009] As a preferred solution of the utility model, the length is 5.8 mm, the width is 5.8 mm, and the height is 7.3 mm.

[0010] Beneficial effects: The structural design of the small-size self-locking electronic switch of the utility model is ingenious. When the self-locking button is pressed, the limit hook enters the limit groove to achieve self-locking. After the limit hook leaves the limit groove, the spring presses the self-locking button to reset to the original position. The state switching is convenient and fast, meeting the use requirements.

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings:

[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have specific directions, be constructed and operated in specific directions. Therefore, they cannot be understood as limitations on the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] like Figures 1 to 3As shown, a small-sized self-locking electronic switch includes a shell 1, a spring 2, an upper cover 3, a self-locking button 4 and a limiting hook 5. A chamber 6 is provided inside the shell 1, and a spring 2 is installed inside the chamber 6. An upper cover 3 is installed above the shell 1, and an opening 7 is provided on the upper cover 3. The lower part of the self-locking button 4 is installed in the chamber 6 and the upper part extends from the opening 7. The upper cover 3 serves to limit the self-locking button 4. The spring 2 presses the self-locking button 4. A limiting groove 8 is provided on the side of the self-locking button 4. A limiting hook 5 is installed on the side of the shell 1. Pressing the self-locking button 4 causes the limiting hook 5 to enter the limiting groove 8 to achieve self-locking.

[0023] like Figure 4-6 As shown, conductive terminals 9 are installed on the side of the housing 1. In this embodiment, the conductive terminals 9 are on both sides, and there are three conductive terminals 9 on each side. The tail of the conductive terminal 9 extends from the housing 1 and is inserted into the PCB board. Correspondingly, the self-locking button 4 is provided with a contact piece 10 corresponding to the position of the conductive terminal. When the self-locking button 4 is in a high position, the two contact pieces 10 on one side contact the corresponding conductive terminal 9, and the other one is disconnected (i.e., 1 and 2 are connected, 4 and 5 are connected, 2 and 3 are disconnected, and 5 and 6 are disconnected). When the self-locking button 4 is pressed down and is in a low position, it is in a self-locking state, and the other ports are connected, i.e., 1 and 2 are disconnected, 4 and 5 are disconnected, 2 and 3 are connected, and 5 and 6 are connected.

[0024] Specifically, the limit groove 8 consists of a first oblique groove 81, a vertical groove 82, a V-shaped groove 83 and a second oblique groove 84. The first oblique groove 81 is connected to the vertical groove 82, the vertical groove 82 is connected to the V-shaped groove 83, and the V-shaped groove 83 is connected to the second oblique groove 84. When the button is pressed, the limit hook 5 enters the V-shaped groove 83 from the first oblique groove 81 and the vertical groove 82 in turn, which is in a self-locking state. When the button is pressed again, the limit hook 5 returns to its original position from the V-shaped groove 83 and the second oblique groove 84 in turn, which is in an unlocked state.

[0025] Specifically, a plug hole 11 is provided inside the chamber 6, one end of the limit hook 5 is inserted into the plug hole 11, the other end of the limit hook 5 extends upward and bends, a positioning cone 12 is provided inside the chamber 6, and the spring 2 is sleeved in the positioning cone 12. The small-size self-locking electronic switch is 5.8 mm long, 5.8 mm wide, and 7.3 mm high.

[0026] The above content is a further detailed description of the utility model in combination with specific preferred implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the protection scope of the utility model.
