[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In one embodiment, see Figures 1-4 A novel push button switch includes a contact base housing 15, with a middle base frame 11 snapped onto the top of the contact base housing 15. A push rod 14 is slidably connected to the middle of the contact base housing 15. A switch base 7 is mounted on the middle base frame 11, and a switch housing 5 is mounted on the switch base 7. A self-locking ring 6 that mates with the switch housing 5 is provided on the outer side of the switch base 7. Moving contact pieces 19 that mate with the push rod 14 are provided on both sides of the contact base housing 15. The contact base housing 15 is an interference fit between the switch body and the top cover, securing the contact feet and spring pieces 21, etc., and has an internal guide groove for the push rod 14 to move up and down. The upper end of the middle base frame 11 is connected to the switch housing 5 via a snap-fit, and the lower end is connected to the contact base housing 15 via a snap-fit, serving as the link between the two. The push rod 14 is the exposed operating component of the contact base assembly, and its exposed length can be varied to meet customer requirements. The switch base 7 is internally connected to the button base 3 and the self-locking ring 6 via rib grooves, and externally connected to the switch housing 5. It is also externally connected to the central frame 11 via a snap-fit. The switch housing 5 includes various outer diameter housings, which can be installed on the panel according to different switch size requirements of customers. Different colors can also be selected according to appearance performance requirements. The upper end of the self-locking ring 6 is connected to the button base 3, and the lower end is connected to the switch base 7. Driven by the button base 3, it moves on the switch base 7 to achieve the self-locking function of the switch. The moving contact component 19 has moving contacts on its surface, possessing good conductivity and wear resistance to ensure the electrical performance requirements of the button switch. When a vertical downward force is applied externally, the switch base 7 moves downward to press the push rod 14. The moving contact spring 18 drives the moving contact component 19 downward. When the movement reaches a certain stroke, the moving contact component contacts the contact foot component, realizing the switch on / off function.

[0021] In one embodiment, a button base 3 is provided on the switch housing 5, a button cover 1 is provided on the button base 3, and a light-diffusing cover 2 is provided between the button cover 1 and the button base 3. A waterproof rubber 4 is fitted over the button base 3. The upper end of the button base 3 is connected to the button cover 1, and the lower end is engaged with the switch housing 5 through a rib groove. The button cover 1 applies force and moves up and down, thereby driving the self-locking ring 6 to press the contact seat push rod 14, realizing the switch on / off function. The button cover 1 is an external operating component, and various colors and patterns are available, which can be selected according to customer needs. The light-diffusing cover 2 utilizes the light transmittance of the material to achieve uniformity of the switch's light emission performance. The inner ring of the waterproof rubber 4 is thicker at the head, providing better inward contraction force, allowing it to fit tightly onto the button base 3. The button base 3 is then used for interference compression to fix it, making it difficult for the rubber to come off during movement. The bottom ring wraps around the head of the base, and the pressure between the switch housing 5 and the switch base 7 ensures that water cannot flow into the switch from this point, thus achieving high waterproof performance of this button switch.

[0022] In one embodiment, a nut 9 is threaded onto the outside of the switch housing 5. A sealing gasket 8 and a mounting panel 23 are disposed between the nut 9 and the switch housing 5. A screw 10 is disposed on the side of the nut 9. The nut 9 and the switch housing 5 are threaded together, allowing the switch to be tightly fitted and fixed to the mounting panel 23. The sealing gasket 8 is made of silicone rubber and is installed on the outside of the switch housing 5. When the switch housing 5 is fastened to the mounting panel 23 by the nut 9, it can effectively prevent water from flowing into the mounting hole on the upper side of the mounting panel 23, ensuring the waterproof performance of the mounting panel 23. The screw 10 is installed on the nut 9, which can increase the tightness between the switches and prevent loosening caused by the rotation of the nut 9.

[0023] In one embodiment, a center seat buckle 13 is provided on the side of the center seat frame 11, and a center seat spring 12 that cooperates with the center seat buckle 13 is provided inside the center seat frame 11. The center seat buckle 13 contains a limiting buckle, which, after being assembled with the center seat frame 11, can prevent the button switch from falling off. Moreover, by pressing and applying force, the limiting structure can be offset, thereby allowing the button switch to disengage. The structure is simple and easy to assemble. The center seat spring 12 has a black surface, good elasticity, and provides force and feel.

[0024] In one embodiment, a contact seat cover 16 is provided on the side of the contact seat housing 15. Inside the contact seat housing 15, a contact foot component 20 is provided to cooperate with the moving contact component. A spring piece 21 and a spring push rod 22 are provided between the contact foot component 20 and the contact seat housing 15. A moving contact spring 18 is provided between the moving contact component 19 and the contact seat housing 15. A push rod spring 17 is provided inside the contact seat housing 15. The contact seat cover 16 and the contact seat housing 15 are fixed with an interference fit. The contact foot component 20, spring piece 21, push rod 14, and other parts cooperate with the contact seat housing 15 to form a cavity. The surface of the contact foot component 20 has a stationary contact, which has good conductivity and wear resistance, ensuring the electrical performance requirements of the push button switch. When the switch is moved, it contacts the moving contact component to realize the switch on / off function. The contact foot is connected to an external circuit. The spring 21 has good elasticity. When the external circuit wires are connected to the contact, the elastic force secures them together, ensuring the stability of the switch connection. The spring push rod 22 is located at the terminal of the contact seat. By applying force, the spring 21 can be compressed and deformed, thus facilitating the connection of the external circuit wires to the contact pin. After the force is released, the spring 21 is secured by the restoring force, preventing the wires from coming out. The moving contact spring 18 has a blackened surface and good elasticity, providing contact force and tactile feedback between the contacts. The push rod spring 17 has a blackened surface and good elasticity, ensuring the reset function of the switch while providing force and tactile feedback.

[0025] In this embodiment, the push-button switch is installed into the mounting panel 23 from above, and the nut 9 is tightened from below and engaged with the screw 10, so that the switch is assembled firmly and conveniently; then it is installed into the middle base frame 11 through the snap-fit ​​structure; finally, the contact base housing 15 is installed into the middle base frame 11 from below.

[0026] When force is applied to the downward button switch, the button cover 1 moves the button base 3 and the self-locking ring 6 downward, thereby pressing the push rod 14 down at the bottom of the self-locking ring 6, and the moving contact piece 19 also moves downward, contacting the contact foot pieces 20 on both sides, connecting the moving and stationary contacts, thus realizing the function of connecting the contact feet at both ends of the switch; when the force is released, the self-locking ring 6 will stop moving due to the structural limitation with the switch base 7, and at this time the moving and stationary contacts are not separated, thus realizing the self-locking function of the switch; finally, when force F is applied again and then released, the self-locking ring 6 will return to its initial state, and the push rod 14 will move upward under the restoring force of the return spring, thereby driving the moving contact piece 19 and separating the moving and stationary contacts on both sides, thus realizing the function of disconnecting the contact feet at both ends of the switch.

[0027] This utility model applies to a novel push-button switch. The inner ring of the waterproof rubber 4 head has a larger round rib, resulting in greater inward contraction force. It can be tightly fitted onto the push-button base 3. The push-button base 3 and the push-button cover are connected by an interference fit, and the flange prevents the waterproof rubber 4 from easily coming off. The bottom is pressed against the switch housing 5 and the switch base 7 by an interference fit, preventing water from entering the switch. These features make the switch more stable and superior in waterproof performance, less prone to coming off, lower in cost, and simpler and more convenient to assemble, making it more suitable for automated assembly. A novel middle seat is used for connection, which uses a snap-fit ​​mechanism. The upper end connects to the push-button switch, and the lower end connects to the contact point base. The internal snap-fit ​​limiter allows for easy replacement and disassembly of the push-button switch. It is easy to assemble, has lower cost, and is suitable for automated assembly. It adopts a new wiring structure. The force generated by the deformation of the spring 21 inside secures the contact foot to the external wire. It also contains a spring push rod 22. By applying force to the spring push rod 22, the spring 21 is deformed, thereby easily removing the external wire. This structure makes the switch simpler and more convenient to connect to the circuit, and the contact is stable and not easy to fall off. It has lower cost, simple and convenient assembly process, and is suitable for automated assembly.
