[0042] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the switch of the utility model. The panel assembly of the utility model is not limited to the description of the following embodiments.

[0043] This embodiment provides a switch having a plurality of scene switches, wherein the plurality of scene switches are controlled by an integral pressing panel, and a single scene switch can be controlled by applying force to different areas of the pressing panel.

[0044] like Figure 1-2 As shown, this embodiment is described by taking a stick-on switch as an example. The stick-on switch includes: a pressing panel 10, a pressing plate 20, a circuit board 30 and a frame structure.

[0045] The circuit board 30 is arranged in the frame structure, and a plurality of key switches 31 are arranged on the circuit board 30; the pressing plate 20 is covered on the circuit board 30 and fixed on the frame structure, and a plurality of switch avoidance holes 21 are arranged on the pressing plate 20 (refer to Figure 7 ) to expose the key switch 31; the pressing panel 10 is arranged on the pressure plate 20 at intervals, and a plurality of keys 11 are arranged on the side of the pressing panel 10 facing the pressure plate 20, and the positions of the keys 11 correspond to the positions of the avoidance hole 21 and the key switch 31, and the keys 11 form a pressing stroke through the intervals; the pressing panel 10 is also provided with a plurality of support columns 12 on the side of the pressing plate 20 to abut against the pressing plate 20, and the plurality of support columns 12 separate the pressing panel 10 into a plurality of deformation areas 13 so that the plurality of keys 11 are respectively located in the plurality of deformation areas 13.

[0046] As an optional embodiment, the pressing panel 10 is square or rectangular, and the multiple support columns 12 are respectively arranged at the center position of the pressing panel 10 and the middle positions of the four edges, dividing the pressing panel 10 into four deformation areas 13, and the button 11 is located at the center position of the four deformation areas 13 or at a position adjacent to the center of the deformation area 13.

[0047] Specifically, Figure 4 As shown, the support columns 12a, 12c and 12d form a deformation area 13a (the area divided by the dotted line in the figure), and the key 11a is set near the center of the deformation area 13a. When the pressing force is applied to the area outside the deformation area 13a, due to the existence of the support columns 12a, 12c and 12d, the deformation caused by the pressing force will not be transmitted to the deformation area 13a, or the amount transmitted to the deformation area 13a is very small, which is not enough to make the key 11a drive the key switch 31 on the circuit board 30.

[0048] Similarly, the support columns 12a, 12c and 12b form a deformation region 13b, and the button 11b is arranged near the center of the deformation region 13b. The support columns 12a, 12d and 12e form a deformation region 13c, and the button 11c is arranged near the center of the deformation region 13c. The support columns 12a, 12e and 12b form a deformation region 13d, and the button 11d is arranged near the center of the deformation region 13d.

[0049] Of course, the above is only a specific implementation of the deformation area 13 enclosed by the support column 12 provided in this embodiment. Based on the initial shape of the pressing panel 10, deformation areas of different numbers or shapes can be enclosed by the support column 12 to meet the required number or shape of the scenario switch.

[0050] In this embodiment, although the pressing panel 10 is an integral panel structure, the pressing panel 10 is divided into different deformation areas 13 by the support column 12. Therefore, when a deformation area 13a is pressed, only the key 11a will be driven to change its stroke to drive the key switch 31, and other deformation areas 13b, 13c or 13d will not be deformed, and thus other key switches will not be driven.

[0051] As a further improvement, Figure 8As shown, a switch indicator light 32 is also provided next to each of the key switches 31, which can be used as a key status prompt, and the user can also identify the deformation area 13 for pressing through the indicator light 32. Preferably, in order to ensure that the light source of the indicator light 32 is focused and improve the prompt effect, a hub 14 is provided next to the key 11 and covers the indicator light 32. The hub 14 is a non-transparent structure, so that the light is gathered in the area of ​​the hub 14, thereby improving the prompt effect.

[0052] In this embodiment, if Figure 2 As shown, the frame structure includes a middle frame 40 and a base 50 , the circuit board 30 , the pressure plate 20 and the pressing panel 10 are sequentially arranged on one side of the middle frame 40 , and the base 50 is arranged on the other side of the middle frame 40 .

[0053] In this embodiment, if Figure 5-6 As shown, the middle frame 40 is provided with a connection platform 41 extending inward from the edge and a circuit board slot 42 formed by a concave middle area of ​​the connection platform 41. Figure 2 and Figure 3 As shown, the circuit board 30 is disposed in the circuit board slot 42 .

[0054] Furthermore, a circuit board support column 421 is provided in the circuit board slot 42 to lift the circuit board 30 to prevent the components of the circuit board 30 from being squeezed with the bottom of the circuit board slot 42. In addition, a circuit board limiting column 422 is also provided in the circuit board slot 42. The circuit board limiting column 422 is arranged above the circuit board support column 421. Figure 8 As shown, a plurality of through-limiting holes 302 are provided on the circuit board 30 , and the circuit board support pillars 421 are inserted into the limiting holes 302 to limit the circuit board 30 .

[0055] In this embodiment, combined with Figure 2 , 3 As shown in FIG. 5 , the shape of the pressing plate 20 corresponds to the circuit board slot 42 , and the pressing plate 20 is embedded in the circuit board slot 42 , and its surface is flush with the connecting platform 41 , thereby reducing the overall thickness of the switch as much as possible.

[0056] Furthermore, the outer periphery of the pressing plate 20 is provided with a pressing plate side wall 22, and the pressing plate side wall 22 is provided with a pressing plate buckle 23. Figure 5-6 As shown, a pressure plate clamping position 44 is provided in the circuit board slot 42, and the pressure plate 20 is clamped to the pressure plate clamping position 44 by the pressure plate buckle 23 to be fixed. The pressure plate side wall 22 and the side wall of the circuit board slot 42 are mutually positioned to play a role in positioning and fixing the pressure plate 20. In addition, the compressive strength of the pressure plate 20 can be improved, thereby playing a role in supporting the support column 12 of the pressing panel 10, and further, the pressure plate buckle 23 provides structural support.

[0057] In this embodiment, Figure 5 and Figure 7 As shown, the pressing plate 20 and the connecting platform 41 are respectively provided with a first limiting groove 207 and a second limiting groove 417 for limiting the end of the supporting column 12 to prevent the supporting column 12 from excessively slipping.

[0058] In this embodiment, if Figure 4 and Figure 5 As shown, the edge area of ​​the pressing panel 10 is provided with a plurality of panel buckles 15 on the side facing the pressing plate 20, and the connecting platform 41 is provided with a plurality of panel clamping positions 415 correspondingly, and the pressing panel 10 is fixed to the panel clamping positions 415 by the panel buckles 15. In this way, a spacing space is formed between the pressing panel 10 and the circuit board 30 and the pressing plate 20 to meet the pressing stroke of the deformation area of ​​the pressing panel 10.

[0059] Furthermore, a plurality of positioning posts 16 are provided on the edge area of ​​the pressing panel 10 facing the pressing plate 20, and a plurality of positioning holes 416 are correspondingly provided on the connecting platform 41, and the positioning posts 16 are inserted into the positioning holes 416, so that the pressing panel 10 can be limited. In addition, a limiting boss 18 is provided on the edge of the pressing panel 10, and a trapezoidal limiting groove 418 is provided on the edge of the connecting platform 41 to further limit the pressing panel 10. The use of the trapezoidal limiting groove 418 is conducive to guiding the pressing direction of the pressing panel 10.

[0060] Furthermore, the edge of the connection platform 41 is provided with a plurality of springs 43 corresponding to the deformation area 13. The springs 43 have a certain elasticity, and when the pressing panel 10 is pressed by an external force, the springs 43 are squeezed, and when the external force is removed, the springs 43 will restore their shape and rebound the pressing panel to its original position.

[0061] like Fig. 9 The base 50 of the free-stick switch in this embodiment is shown, and the outer side of the side wall of the base 50 is provided with a base clamping position 51, correspondingly, as shown in FIG. Figure 6 As shown, the side wall of the middle frame 40 is provided with a middle frame buckle 407 for snapping onto the base snapping position 51. The base 50 is also provided with a screw hole 52. When the base is mounted on a wall, the screw can be inserted into the mounting groove or surface of the wall through the screw hole 52 to fix the base; of course, the base can also be fixed to a desktop or wall by sticking the base to a ring-shaped adhesive tape of the same shape as the base. The base 50 in this embodiment is a ring-shaped frame structure, such as Figure 4 As shown, the middle frame 40 has a ring-shaped groove 408 on one side facing the base corresponding to the connection platform 41, and the base 50 is embedded in the ring-shaped groove 408, so that the thickness of the switch is not increased.

[0062] In this embodiment, if Figure 2 and Figure 6 As shown, since it is a stick-on switch and a switch structure that does not require wiring, the circuit board 30 is provided with a battery (not shown in the figure). Based on this, in order to realize the replaceable battery, a battery cover 427 is provided at the bottom of the circuit board slot 42, and a battery cover 60 is correspondingly provided to close the battery cover 427. When the battery is exhausted, the battery can be replaced through the battery cover 427.
