Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model discloses a push-button switch, such as Figures 1-5 As shown, the assembly includes a soft pressing shell 1, an outer shell 2, a pressing component 5, and a circuit board 4. The soft pressing shell 1 is located on top of the pressing component 5 and is connected to the outer shell 2. The pressing component 5 consists of an indicator shell 50 and an elastic key 51. The top of the internal cavity of the indicator shell 50 is provided with reinforcing rib protrusions 10, and two sets are provided, which can effectively enhance the overall structural strength of the indicator shell 50 and keep it stable under frequent pressing operations. The top of the elastic key 51 is provided with a groove 11 that cooperates with the reinforcing rib protrusion 10, and the two sides have crescent-shaped protrusions 21. The internal cavity of the indicator shell 50 is provided with a crescent-shaped groove (20) that cooperates with it, so that the pressing force can be evenly and accurately transmitted to the elastic key, the connection is more stable and the fit is more precise. When pressing, the force can be effectively transmitted and evenly distributed, which effectively improves the stability of pressing.

[0022] The elastic key 51 has an integrally formed frustoconical protrusion 111 that connects to the micro-motion component 30 below it. A return spring 3 is fixedly installed between the micro-motion component 30 and the elastic key 51. The top of the micro-motion key 301 is hemispherical, and the top of the frustoconical protrusion 111 has a hemispherical groove 113, which connects to each other. In addition, the hemispherical top of the micro-motion key 301 and its engagement with the hemispherical groove 113 at the top of the frustoconical protrusion 111 make the force transmission between the two smoother and more concentrated, reducing friction and jamming, thereby improving the switch's pressure resistance. The micro-motion components 30 are interconnected through the positioning grooves 7 provided in the base 8. The bottom of the base 8 is provided with a bracket frame 40 for mating and overlapping. The circuit board 4 is placed in the bracket frame 40, and a conductive sheet 9 is provided at its bottom. The electronic component 6 is attached below the conductive sheet 9. The outer shell 2 is composed of two parts, outer shell A and outer shell B, which are connected by a snap fastener to form two upper and lower accommodating cavities after connection. The outer shell 2 has a protrusion 201 on its side, and a threaded hole 202 is provided on the protrusion 201 to make assembly more convenient and to make maintenance and replacement of internal parts faster.

[0023] Furthermore, the pressable soft shell 1 is made of rubber with a transparent outer surface, which allows the built-in indicator shell to be clearly seen. The indicator shell is not only inexpensive to manufacture, but can also be produced in different colors to meet diverse needs. Its ease of disassembly and replacement effectively reduces production costs and material consumption.

[0024] Working principle: in the initial state, press the switch components in the state of no force, press the soft shell 1, indicating shell 50, elastic key 51, micro motion assembly 30 and so on all keep its inherent form and position relationship, the circuit is in the open state. When press the soft shell 1, the pressure is transmitted to the indicating shell 50 through the soft shell 1. Indicating shell 50 is forced to cooperate with the elastic key in the internal cavity through the set reinforcing rib boss 10, at the same time also through the set half moon shaped convex rib 21, its internal cone platform convex 111 synchronous downward and act on the micro motion assembly 30, force is smoothly, concentratedly transmitted between the two, so as to compress the return spring 3, at the same time push the micro motion key 301 to move downward. This movement will trigger the contact or break between the conductive sheet 9 on the circuit board 4 and the electronic element 6, so as to complete the on-off operation of the circuit. Once the user releases the pressure on the soft shell 1, the return spring 3 will push the elastic key 51 and the micro motion assembly 30 back to the initial position.

[0025] The above only for the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. within the design concept of the present application, should be included in the protection scope of the present application.
