The swinging block 5 can swing up and down in the left-right direction relative to the pressing plate 4. On the left and right sides of the top of the pressing plate 4, outer baffles 402 are respectively provided. On the left and right sides of the top of the swinging block 5, inner baffles 501 are respectively provided. A connecting rod 6 is provided between the outer baffles 402 on the left and right sides and the inner baffles 501 on the left and right sides respectively. When the button 1 rotates by a first angle, the button 1 will drive the connecting rod 6 to rotate by a second angle, and the connecting rod 6 will drive the swinging block 5 to rotate by a third angle, where the first angle < the third angle < the second angle. A circuit switch assembly 7 is provided at the bottom of the pressing plate 4. The swinging block 5 can trigger the circuit switch assembly 7 through swinging. Functions: (1) By including a button, with a functional component provided below the button, the button can swing up and down in the left-right direction relative to the pressing plate, and the functional component includes the pressing plate and a swinging block arranged inside the pressing plate, and the swinging block can swing up and down in the left-right direction relative to the pressing plate; thus enabling both the button and the swinging block to swing up and down in the left-right direction relative to the pressing plate.

When the button rotates by a first angle, the button will drive the connecting rod to rotate by a second angle, and the connecting rod will drive the swinging block to rotate by a third angle, where the first angle < the third angle < the second angle; thus enabling the button, through the amplification effect of the connecting rod, when the button swings by a first angle (such as 2.0 degrees), the connecting rod swings by a second angle (such as 10.6 degrees), and the swinging block has swung by a third angle (such as 3.4 degrees), playing an angle amplification role. (3) By providing a circuit switch assembly at the bottom of the pressing plate, the swinging block can trigger the circuit switch assembly through swinging; thus enabling the swinging of the swinging block to trigger the circuit switch assembly, and further realizing the on or off of the switch. From the above analysis, it can be seen that through the amplification structure of the connecting rod in this switch, when the button rotates by a first angle (such as 2.0 degrees), through the amplification effect of the connecting rod, the swinging block can rotate by a third angle (such as 3.4 degrees), realizing the function of driving a large angle with a small angle, making the switch thickness thinner and enhancing the aesthetic feeling.

[0039] Specifically, a swinging groove 401 is provided in the middle of the pressing plate 4. The swinging block 5 is arranged inside the swinging groove 401. The bottom of the swinging block 5 extends to the outside of the swinging groove 401 and can trigger the circuit switch assembly 7 through swinging. The outer edge of the connecting rod 6 is rotatably connected to the outer baffle 402, and the inner edge of the connecting rod 6 is in limit cooperation with the inner baffle 501. The middle of the connecting rod 6 arches upward so that the acting force of the button 1 can drive the connecting rod 6 and the swinging block 5 to rotate in sequence. Function: With such a setting, the button 1 can better realize the function of driving a large angle with a small angle through the amplification effect of the connecting rod.

[0040] Specifically, the outer baffle plate 402 is in the shape of a V-shaped plate with an opening facing downward, and two third rotation grooves 403 distributed along the front and back are provided in the middle of the outer baffle plate 402, and a plurality of elastic buckles 602 distributed along the front and back are provided on the outer edge of the connecting rod 6, and a third rotation axis 601 and a limit block 603 are provided on the elastic buckle 602; the two third rotation axes 601 are respectively rotatably matched with the two third rotation grooves 403, and the two limit blocks 603 are respectively limitedly matched with the front and rear sides of the outer baffle plate 402.

Function: Through rotational matching, the key and the swing block can better swing up and down in the left and right directions relative to the pressure plate.

[0042] Specifically, the bottom of the swing block 5 is provided with an assembly hole 503, in which a switch spring 504 and a pin 505 are installed, the switch spring 504 is arranged above the pin 505, the pin 505 extends downward to the outside of the assembly hole 503 and can trigger the circuit switch assembly 7 by swinging. Function: By setting the switch spring 504, the pin 505 has elastic force.

[0043] Specifically, the circuit switch assembly 7 includes a first switch static contact piece 701, a switch bracket 702, a second switch static contact piece 703, and a switch springboard 704. The switch bracket 702 is located below the middle of the switch springboard 704 and contacts to form a fulcrum. The pin 505 can press down the two sides of the switch springboard 704 by swinging, so that the switch springboard 704 can swing up and down around the switch bracket 702. The two ends of the switch springboard 704 can contact the first switch static contact piece 701 and the second switch static contact piece 703 by swinging. Function: Since the first switch static contact piece 701, the switch bracket 702, and the second switch static contact piece 703 are fixed, and the switch springboard 704 can rotate, the switch bracket 702, as a fulcrum for swinging, always keeps in contact with the middle of the switch springboard 704; when one side of the key is tilted, the switch springboard 704 can always contact with the first switch static contact piece 701, and the contact is pressure (the pressure from the pin, such as Figure 17As shown in the figure, at this time, the switch springboard 704 and the second switch static contact piece 703 are not in contact, and the switch is off; when the other side of the button tilts up, the switch springboard 704 and the second switch static contact piece 703 are in contact, and the switch is on.

Function: When the swing block rotates 3.4 degrees (as Figure 17 shown, the button is pressed on the left side and tilted up on the right side), the ball 505 swings to the right side of the middle of the switch springboard 704. At this time, the switch springboard 704 forms a left tilt and a right drop around the bracket fulcrum 7021; in the static state, when pressing the tilted side of the button (not shown in the figure, the button is pressed on the right side and tilted up on the left side), through the connecting rod, the swing block is driven to rotate, the ball slides across the central position and swings to the left side of the middle of the switch springboard 704. At this time, the switch springboard 704 forms a right tilt and a left drop around the bracket fulcrum 7021, and the switch springboard 704 rotates and contacts the other end to complete a switch action.

[0045] Specifically, a switch rear seat 8 is assembled at the bottom of the pressure plate 4. The first switch static contact piece 701, the switch bracket 702, and the second switch static contact piece 703 are assembled in the cavity between the pressure plate 4 and the switch rear seat 8. A card slot 801 is provided at the bottom of the switch rear seat 8.

The top edge of the mounting bracket 3 is provided with an annular groove 301, and the bottom edge of the button 1 is provided with a rectangular frame 101. The rectangular frame 101 can cooperate with and disengage from the annular groove 301 through the swing of the button 1. Function: The overall structure of the button 1, the functional component 2, and the mounting bracket 3 is a modular structure, which facilitates assembly. The cooperation between the rectangular frame 101 and the annular groove 301 also makes it more convenient to accurately press the button.

[0047] Specifically, the front and rear side walls of the rectangular frame 101 are respectively provided with first rotating grooves 102, and the front and rear side edges of the annular groove 301 are respectively provided with first rotating shafts 302.
