[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] As shown in the figure, a five-way tactile switch includes a base 1, a conductive plate 2, a spring 3, a directional button 4, a center button 5, and a cover 6. The conductive plate 2 is disposed inside the base 1 and contacts the circuit embedded in the base 1. The spring 3 is disposed inside the base 1 and located on the conductive plate 2. The cover 6 is snapped onto the base 1 and a limiting ring 61 is formed on the cover 6. The center button 5 passes through the directional button 4. The directional button 4 is disposed inside the base 1 and passes through the limiting ring 61, engaging with the spherical surface of the limiting ring 61. The switch also includes a cylindrical dust cover 7 made of flexible material with openings at the top and bottom. The lower end of the dust cover 7 is fixedly connected to the cover 6, so that the dust cover 7 surrounds the outside of the directional button 4 and the center button 5. The upper end of the dust cover 7 is fixedly connected to the part of the center button 5 that protrudes from the directional button 4. A sealing gasket 8 is provided between the cover 6 and the base 1.

[0025] Specifically, the dust cover 7 is fixedly connected to the cover 6 and the center button 5 at both ends: the upper end of the limiting ring 61 is bent outward to form a connecting ring 62, the side of the center button 5 that protrudes from the direction button 4 is provided with a connecting groove 51, and the upper and lower ends of the dust cover 7 are respectively formed with a first connecting part 71 and a second connecting part 72 that match the connecting groove 51 and the connecting ring 62. The first connecting part 71 is inserted into the connecting groove 51, and the second connecting part 72 is fastened to the connecting ring 62.

[0026] In the above structure, the directional button 4 swings within the base 1 through its spherical engagement with the limiting ring 61. Moving the center button 5 causes the directional button 4 to swing, or pressing the center button 5 causes it to slide within the directional button 4. This compresses the corresponding spring piece 3, causing it to contact the circuit embedded in the base 1 on the conductive plate 2, thus conducting the circuit and achieving the corresponding control function. When the center button 5 moves the directional button 4 or slides within the directional button 4, the center button 5 applies force to the dust cover 7 made of a flexible material (e.g., silicone rubber), causing the dust cover 7 to deform with the movement of the center button 5. This allows the center button 5 to move freely, achieving the control function of a touch switch. Throughout this process, the dust cover 7 always surrounds and remains outside the directional button 4 and the center button 5, covering the area between the directional button 4 and the cover 6, and between the center button 5 and the directional button 4. The gaps prevent external dust from seeping into the base 1 through the gaps between the directional button 4 and the cover 6, and between the center button 5 and the directional button 4. Simultaneously, the sealing gasket 8 located between the cover 6 and the base 1 prevents external dust from seeping into the base 1 through the gaps between the cover 6 and the base 1. This provides the tactile switch with better dustproof performance, ensuring its stability during use. Furthermore, the restoring force generated by the deformation of the center button 5 assists in the quick reset of the center button 5 and the directional button 4, improving the tactile feel of the switch. Additionally, the upper and lower ends of the dust cover 7 are fixedly connected to the center button 5 and the cover 6 through the insertion of the first connecting part 71 into the connecting groove 51 and the fastening of the second connecting part 72 into the connecting ring 62, respectively. This makes the dust cover 7 easy to install and remove, facilitating assembly during tactile switch production and maintenance during use.

[0027] Furthermore, based on the above structure, a plurality of limiting protrusions 73 are formed on the inner wall of the lower end of the dust cover 7, and a limiting groove 63 matching the limiting protrusions 73 is provided on the connecting ring 62. The limiting protrusions 73 are inserted into the limiting grooves 63. The rotation of the dust cover 7 relative to the connecting ring 62 is limited by the cooperation between the limiting protrusions 73 and the limiting grooves 63, thereby strengthening the stability of the dust cover 7 fixedly connected to the cover 6.

[0028] Furthermore, based on the above structure, the side of the dust cover 7 is spherical, and several longitudinally extending reinforcing ribs 74 are formed on the side of the dust cover 7. The reinforcing ribs 74 are distributed in the four directions of the swing of the direction button 4. The spherical side of the dust cover 7 makes the dust cover 7 more stable when it deforms with the center button 5, improving the durability of the dust cover 7. The reinforcing ribs 74 make the dust cover 7 generate a greater restoring force when it deforms with the center button 5, so that the dust cover 7 can better assist the center button 5 and the direction button 4 to reset, further improving the operating feel of the tactile switch.

[0029] Additionally, the upper surface of the base 1 is provided with a plurality of positioning posts 11, and the sealing gasket 8 is provided with a plurality of positioning holes 81 that match the positioning posts 11. The positioning posts 11 pass through the positioning holes 81 and abut against the cover 6. The positioning posts 11 and the positioning holes 81 cooperate to limit the displacement of the sealing gasket 8 on the base 1, ensuring the stability of the sealing gasket 8 between the base 1 and the cover 6. After the positioning posts 11 pass through the positioning holes 81 and abut against the cover 6, they provide support for the cover 6, ensuring the stability of the cover 6 when it is snapped onto the base 1.

[0030] Furthermore, based on the above structure, four positioning blocks 12 are formed inside the base 1, located in pairs on both sides of the swing direction of the direction button 4. Several positioning grooves 41 are opened on the lower end surface of the direction button 4. The positioning blocks 12 are located in the positioning grooves 41 and abut against the bottom of the positioning grooves 41. The positioning blocks 12 provide support for the direction button 4 by abutting against the bottom of the positioning grooves 41, ensuring the stability of the direction button 4 when it swings with the center button 5, thereby improving the operating feel of the tactile switch. In addition, when the center button 5 slides in the direction button 4 and squeezes the spring 3, the positioning blocks 12 provide guidance for the center button 5, ensuring the stability of the center button 5 when it slides, thereby improving the operating feel of the tactile switch.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
