[0002] In recent years, with the development of wireless communication and information technology, various consumer electronic products such as personal computers and mobile phones have developed rapidly, enabling consumers to enjoy various conveniences brought by high technology. At the same time, the functions of these electronic products have become increasingly diversified, and it is necessary to switch between different functions. To facilitate the switching between different functions, switches are provided on the peripheries of these electronic products. However, in existing switches, one switch is used to control the connection or disconnection of one circuit. At this time, it can meet general usage situations. However, in some special cases, it is necessary to control the mutual conversion between normally open and normally closed circuits through one switch. At this time, if an ordinary switch is used, this requirement cannot be achieved. Summary of the Invention

[0003] The purpose of the present invention is to provide a single-pole double-throw push-button switch in which the switching action can control the mutual conversion between a normally open circuit and a normally closed circuit formed by a terminal assembly.

[0004] To solve the above technical problems, the present invention can adopt the following technical solutions to achieve:

The terminal assembly is disposed inside the base. A first through hole is provided in the middle of the face cover. The button is disposed inside the base and the face cover through the first through hole and is cooperated with the terminal assembly through the spring. The terminal assembly includes a first static terminal, a second static terminal, a first moving terminal, and a second moving terminal. The first moving terminal and the second moving terminal are respectively disposed on both sides of the button. The button includes a button shaft and a sliding block. The button shaft and the sliding block are movably connected. A first pressing portion protruding outward is provided on one side of the button shaft, and a second pressing portion protruding outward is provided on the other side of the sliding block. The first pressing portion and the second pressing portion are symmetrically arranged.

[0006] Further, the first static terminal and the second static terminal are integrally connected to each other at the bottom. First connecting portions are provided on both the first static terminal and the second static terminal, and a first wiring portion is further provided at the bottom of the first static terminal, which is the common end of the circuit. One ends of the first moving terminal and the second moving terminal are respectively provided with a spring pressing portion and a second connecting portion. The other ends of the first moving terminal and the second moving terminal are respectively provided with a second wiring portion and a third wiring portion, which are the normally open end and the normally closed end of the circuit. The first wiring portion, the second wiring portion, and the third wiring portion respectively penetrate through the base and are disposed outside the base.

[0007] Further, a pressing column and hooks are provided in the middle of the pressing shaft. The hooks are respectively arranged on both sides of the pressing column. A second through hole is provided in the middle of the sliding block, and step grooves are respectively provided on both sides of the second through hole. The hooks pass through the second through hole and cooperate with the step grooves.

[0008] Further, the base is provided with a hollow column. The pressing column passes through the second through hole and cooperates with the hollow column. The spring is arranged between the pressing shaft and the base, surrounds the pressing column and the hollow column, and is respectively abutted against the pressing shaft and the base at both ends.

[0009] Further, limiting blocks are respectively provided on the other two sides of the pressing shaft and the sliding block, and limiting grooves cooperating with the limiting blocks are respectively provided on both sides of the base and the face cover.

[0010] The beneficial effects of the present invention are as follows: The single-pole double-throw push-button switch of the present invention makes the pressing shaft move downward by pressing the button, and through the interaction between the first pressing part of the pressing shaft and the elastic pressing part of the first moving terminal, the second connecting part of the first moving terminal and the first connecting part of the first static terminal are changed from being connected to being disconnected. When the pressing shaft is pressed down to a certain position, the sliding block moves downward, so that the second pressing part of the sliding block is separated from the elastic pressing part of the second moving terminal and loses the interaction therewith. Thus, the second connecting part of the second moving terminal comes into contact with the first connecting part of the second static terminal, and the circuit is changed from being disconnected to being connected to each other. After operation, the sliding block and the pressing shaft are reset by the spring, so as to realize the mutual conversion of the normally open and normally closed circuits formed by the terminal assembly controlled by one switch action, and the structure is simple and reasonable; the assembly of its single-pole double-throw push-button switch is also extremely convenient.

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the products of the present invention will be further described in detail below in conjunction with the embodiments and the attached drawings.

[0021] As Figures 1 to 8As shown in the figure, a single-pole double-throw push-button switch includes a base 1, a face cover 2, a button 3, a terminal assembly 4, and a spring 7. The face cover 2 is snap-connected to the base 1. The terminal assembly 4 is disposed inside the base 1. A first through hole 5 is provided in the middle of the face cover 2. The button 3 is disposed inside the base 1 and the face cover 2 through the first through hole 5 and is matched with the terminal assembly 4 through the spring 7. The terminal assembly 4 includes a first static terminal 41, a second static terminal 42, a first moving terminal 43, and a second moving terminal 44. The first moving terminal 43 and the second moving terminal 44 are respectively disposed on both sides of the button 3. The button 3 includes a button shaft 31 and a sliding block 32. The button shaft 31 and the sliding block 32 are movably connected. A first pressing portion 33 protruding outward is provided on one side of the button shaft 31. A second pressing portion 34 protruding outward is provided on the other side of the sliding block 32. The first pressing portion 33 and the second pressing portion 34 are symmetrically arranged. The single-pole double-throw push-button switch of the present invention is composed of a base, a face cover, a button, a terminal assembly, and a spring. The components are few, and the structure is simple and reasonable. The face cover and the base can be snap-connected, and can also be connected by riveting, screw connection, etc., making it convenient to disassemble. The first pressing portion is provided on one side of the button shaft, and the second pressing portion is provided on the side of the sliding block opposite to the first pressing portion. In the original state of the circuit, the first moving terminal and the first static terminal are kept in an open state, and the second moving terminal and the second static terminal are kept in a closed state. When the circuit is switched, by pressing the button shaft of the button, it moves downward. The first pressing portion of the button shaft acts on the first moving terminal, causing the first moving terminal and the first static terminal to be separated and disconnected. At the same time, when the button shaft is pressed down to a certain position, it drives the sliding block of the button to move downward, causing the second moving terminal to lose the acting force of the second pressing portion, so that the second moving terminal and the second static terminal are connected to each other. After switching, through the reaction force of the spring, the button shaft and the sliding block are reset and restored to the original state, so as to achieve the mutual conversion of the normally open and normally closed circuits formed by a switch action. And its operation is simple and reasonable, only need to press the button. During the conversion process, it can also maintain the unique wave contact feel and the "click" pleasant sound function of a mechanical ordinary push-button switch.

[0022] As Figure 3As shown in the figure, the first static terminal 41 and the second static terminal 42 are integrally connected to each other at the bottom. The first static terminal 41 and the second static terminal 42 are both provided with a first connection portion 411, and the bottom of the first static terminal 41 is further provided with a first wiring portion 412, which is the common end of the circuit. One end of the first moving terminal 43 and the second moving terminal 44 is provided with a spring pressing portion 45 and a second connection portion 46 respectively. The other ends of the first moving terminal 43 and the second moving terminal 44 are provided with a second wiring portion 47 and a third wiring portion 48 respectively, which are the normally open end and the normally closed end of the circuit. The first wiring portion 412, the second wiring portion 47, and the third wiring portion 48 respectively penetrate through the base 1 and are arranged outside the base 1. When the circuit is in the original state, the first pressing portion is separated from the spring pressing portion of the first moving terminal, so that the second connection portion of the first moving terminal is connected to the first connection portion of the first static terminal, and the second pressing portion interacts with the spring pressing portion of the second moving terminal, so that the second connection portion of the second moving terminal is separated from the first connection portion of the second static terminal. When the circuit is switched, by pressing down the pressing shaft, the pressing shaft moves downward, so that the first pressing portion contacts the spring pressing portion of the first moving terminal and generates a certain acting force, so that the second connection portion of the first moving terminal is separated from the first connection portion of the first static terminal. At the same time, the pressing shaft drives the sliding block to move downward, separating the second pressing portion from the spring pressing portion of the second moving terminal, so that the second connection portion of the second moving terminal is connected to the first connection portion of the second static terminal. After the switching is completed, through the reaction force of the spring, the pressing shaft and the sliding block are reset and the circuit returns to the original state, so as to realize the mutual conversion of the normally open and normally closed circuits formed by the terminal assembly controlled by a single switch action.

[0023] As Figures 4 to 6 shown in the figure, a pressing column 311 and a hook 312 are provided in the middle of the pressing shaft 31. The hooks 312 are respectively arranged on both sides of the pressing column 311. A second through hole 321 is provided in the middle of the sliding block 32. Step grooves 322 are respectively provided on both sides of the second through hole 321. The hooks 312 pass through the second through hole 321 and cooperate with the step grooves 322. The pressing shaft and the sliding block can be slidably connected. Through the cooperation of the hooks and the step grooves, the pressing shaft and the sliding block can slide relative to each other, and they will not be separated through the step grooves. And through the second through hole, the pressing column can be kept in cooperation with the base to realize the button function, so that the structure of the single-pole double-throw push-button switch is simple and can operate reasonably.

[0024] As Figure 7As shown, the base 1 is provided with a hollow column 6. The pressing column 311 passes through the second through hole 321 and cooperates with the hollow column 6. The spring 7 is arranged between the pressing shaft 31 and the base 1, surrounds the pressing column 311 and the hollow column 6, and abuts against the pressing shaft 31 and the base 1 at both ends respectively. When pressing the pressing shaft, the pressing column moves into the hollow column to achieve the operation. After completing the circuit switching control, the pressing shaft and the sliding block are bounced up and reset by the rebounding force of the spring, so that the operation of the single-pole double-throw push-button switch is convenient and the structure is reasonable and operable.

[0025] As Figure 7 and Figure 8 shown, the pressing shaft 31 and the sliding block 32 are respectively provided with limiting blocks 35 on the other two sides. The base 1 and the face cover 2 are respectively provided with limiting grooves 8 that cooperate with the limiting blocks 35. The limiting grooves on both sides of the base and the face cover can limit the pressing shaft and the sliding block, so that the pressing shaft and the sliding block will not deviate during operation, thereby improving the quality of the single-pole double-throw push-button switch and extending its service life.
