the cover plate 150 is arranged on one side of the face cover 110, which faces away from the circuit board 120; the cover plate 150 is provided with a touch control area 152 and a key area 151 which are arranged in a staggered manner; the touch area 152 is disposed corresponding to the touch switch 130, and is used for triggering the touch switch 130; the key region 151 is disposed corresponding to the micro switch 140, and is used for triggering the micro switch 140.

In the technical scheme of the application, the touch area 152 and the key area 151 are arranged on the cover plate 150 in a staggered manner, and the projections of the touch switch 130 corresponding to the touch area 152 and the case switch 10 corresponding to the key area 151 on the circuit board 120 are arranged in a staggered manner, so that the touch switch 130 and the micro switch 140 can be triggered at different positions on the same cover plate 150, and a first electrical signal and a second electrical signal can be input to the circuit board 120. According to the embodiment of the application, two control modes of key pressing and touch control can be realized on the same cover plate 150, and a mechanical key structure and a touch control trigger structure are integrally compatible.

It should be noted that the micro switch 140 may be soldered on the circuit board 120. The circuit board 120 can control the corresponding electrical device to operate based on the first electrical signal and the second electrical signal, for example, to achieve the control purpose of turning on or off the light, adjusting the brightness of the light, and adjusting the color of the light, so as to drive the innovation of the intelligent control panel of the smart home.

Further, it should be noted that the cover plate 150 may be a key glass.

As an alternative to the above embodiment, as shown in fig. 4 and 5, the surface cover 110 has a first side surface 110a and a second side surface 110b; the circuit board 120 is disposed to face the first side surface 110a, and the cover plate 150 is disposed to face the second side surface 110 b. The touch switch 130 comprises a touch pad 132 and a conductive member 131; the conductive member 131 is a deformable member; the touch pad 132 is electrically connected to the circuit board 120 and attached to the first side surface 110a; the conductive member 131 is attached to the second side surface 110b, is disposed opposite to the touch region 152, and is disposed corresponding to the touch pad 132 to form a capacitor. In the embodiment, the touch pad 132 and the conductive member 131 are both conductors, and are respectively attached to two opposite sides of the cover 110; since the surface cover 110 is an insulator, a capacitor is formed between the conductive member 131 and the touch pad 132. When the touch region 152 of the cover plate 150 is pressed, the conductive member 131 is deformed, and thus the capacitance between the conductive member and the touch pad 132 is changed, thereby outputting a first electrical signal to the circuit board 120.

For example, in an embodiment, the conductive member 131 may be a conductive foam. The conductive member 131 and the touch pad 132 are both attached to the surface cover 110, so as to realize a 0-gap fit. Generally, the conductive member 131 and the touch pad 132 are both adhered to the cover 110.

In the embodiment, the face cover 110 is configured with a receiving cavity in which the circuit board 120 is disposed. The circuit board 120 may be fixed to the face cover 110 by screws. The circuit board 120 is disposed facing the first side 110a of the face cover 110. The first side surface 110a is an inner side surface of the surface cover 110. The surface cover 110 further has a second side surface 110b disposed opposite to the first side surface 110a in the thickness direction, and the second side surface 110b is an outer side surface of the surface cover 110.

As an optional implementation manner of the above embodiment, as shown in fig. 4 and fig. 5, the face cover 110 includes a plurality of limiting strips 1102, and the limiting strips 1102 are protruded from the second side surface 110b and enclose to form an accommodating space; the conductive member 131 is disposed in the accommodating space and abuts against the plurality of limiting strips 1102. The plurality of limiting strips 1102 are arranged to define a containing space for arranging the conductive piece 131, the conductive piece 131 is placed in the containing space, and the conductive piece 131 is abutted against the plurality of limiting strips 1102, so that the limiting strips 1102 limit the movement of the conductive piece 131. For example, if the conductive members 131 are square, the number of the limiting strips 1102 is four, and the limiting strips are sequentially connected end to form a square accommodating space; the four side surfaces of the conductive member 131 are respectively abutted against the four limit strips 1102, so as to limit the movement of the conductive member 131.

As an alternative to the above embodiment, as shown in fig. 3, the switch 10 further includes a key holder 160. As shown in fig. 2 and 4, the key holder 160 is disposed facing the second side surface 110b and is fixedly connected to the surface cover 110. The side of the key holder 160 facing away from the face cover 110 is tightly attached to the cover plate 150. The key holder 160 and the cover plate 150 are tightly attached, that is, a gap of 0 is formed between the key holder 160 and the cover plate 150, so that the keys are pressed in the key region 151 or the touch region 152 to cause corresponding deformation between the keys, and further, the micro switch 140 can be triggered or the conductive member 131 can be deformed.

As an alternative to the above embodiment, as shown in fig. 8, a key rib 161 is configured on a side of the key holder 160 facing the cover plate 150, and the key rib 161 is disposed corresponding to the key region 151; the key ribs 161 are arranged corresponding to the micro switches 140; wherein, when the key region 151 is not pressed, there is a gap between the key rib 161 and the micro switch 140; when the key region 151 is pressed, the key rib 161 is in contact with the micro switch 140. In an embodiment, the key ribs 161 may be cross ribs, V-shaped ribs or shaped ribs, which are protruding structures protruding from the side of the key holder 160 facing the cover plate 150 and low, and are intended to be able to access the micro switch 140. When the key area 151 is not pressed, the key support 160 is not deformed, and the key rib 161 is located at the first position with a gap from the micro switch 140. When the key area 151 is pressed, the key support 160 deforms, and at this time, the key rib 161 displaces to be located at the second position, a gap is formed between the key rib 161 and the microswitch 140, and the key rib 161 is temporarily eliminated, and is in contact with the microswitch 140, so that the microswitch 140 is triggered; when the pressure of the key area 151 is removed, the key support 160 rebounds, and at this time, the key rib 161 displaces to return to the first position, and the gap between the key rib and the microswitch 140 is restored to the state with the gap.

As an alternative embodiment of the above embodiment, as shown in fig. 6, the face cover 110 further has a receiving through hole 1101 penetrating the first side face 110a and the second side face 110b, and the micro switch 140 is disposed in the receiving through hole 1101. In an embodiment, as shown in fig. 4 and 7, the micro switch 140 is disposed on the circuit board 120 and is located in the receiving through hole 1101. On one hand, positioning the micro-switch 140 in the receiving through-hole 1101 can reduce the thickness of the switch 10; on the other hand, the key holder 160 and the circuit board 120 are disposed on two opposite sides of the face cover 110, the micro switch 140 is disposed on the circuit board 120, and the key ribs 161 are structures on the key holder 160, so that the receiving holes 1101 give way for the key ribs 161, so that the key ribs 161 can extend into the receiving holes 1101 to contact the micro switch 140.

As an optional implementation manner of the above embodiment, the conductive component 131 is tightly attached to the key holder 160. The zero-gap design between the conductive member 131 and the key holder 160 allows the conductive member 131 to deform when the touch region 152 is pressed, so as to generate capacitance change, so as to input an electrical signal to the circuit board 120.

As an optional implementation manner of the above embodiment, a value of the gap ranges from 0.2mm to 0.4mm. When pressure is applied to the key region 151, the key supporter 160 is locally deformed and the key ribs 161 are displaced by 0.2-0.4mm to touch the micro switch 140, so that the micro switch 140 outputs a second electrical signal to the circuit board 120.

As an alternative to the above embodiment, the key holder 160 has a positioning post 162 extending toward the face cover 110; the face cover 110 has positioning holes 1103; the positioning post 162 is in interference fit with the positioning hole 1103. In an embodiment, the key holder 160 is fixedly coupled to the face cover 110. When the touch area 152 or the key area 151 is pressed, the key holder 160 does not move integrally along the thickness direction of the switch 10, but deforms at the corresponding position, so as to deform the conductive member 131 (and thus change the capacitance) or partially displace the key rib 161 to trigger the micro switch 140. In the embodiment, the number of the positioning posts 162 and the positioning holes 1103 is specifically set according to specific situations. For example, in some embodiments, four positioning posts 162 and four positioning holes 1103 are provided.

In order to satisfy the purpose of intelligent control, in an embodiment, the number of the touch switches 130 is multiple, the touch switches 130 are arranged at intervals, the number of the touch areas 152 is the same as the number of the touch switches 130, and the touch switches 130 and the touch areas 152 are arranged in a one-to-one correspondence; and/or the number of the micro switches 140 is multiple, the micro switches 140 are arranged at intervals, the number of the key areas 151 is consistent with that of the micro switches 140, and the micro switches 140 and the key areas 151 are arranged in a one-to-one correspondence manner. For example, as shown in FIG. 1, in some embodiments, the cover plate 150 is generally square in configuration. The number of the key regions 151 is four, and the four key regions are respectively close to four corners of the cover plate 150. The number of the touch areas 152 is two, and the touch areas are respectively disposed between the two key areas 151.

In summary, the switch 10 provided in the embodiment of the present application has the following advantages: the key area 151 and the touch area 152 are integrated on the cover plate 150, so that the touch switch 130 and the physical switch 10 are compatible and do not interfere with each other in a two-in-one manner, and the whole body is attractive; the clearance in the switch 10 structure is easily managed and controlled, is favorable to improving production efficiency, reduces the cost of doing over again to promote the market competition of product.
