[0013] In one or more embodiments of the present disclosure, when the sliding body drives the second conductive member to move via the elastic body, the second swing plate is supported by the elastic body and swings, so that the second conductive plate moves toward the first conductive plate.

[0014] In one or more embodiments of the present disclosure, the capacitive switch device further includes a flexible body located between the first conductive member and the second conductive member. The flexible body abuts against the second conductive member so that a non-zero distance exists between the second conductive member and the first conductive member. The second conductive member is located above the first conductive member, and the flexible body passes through the first conductive member. The first direction is parallel to the second direction.

[0015] In order to achieve the above-mentioned purpose, according to one embodiment of the present disclosure, a capacitive switch device includes a lower cover, an upper cover, a sliding body, an elastic body, a first conductive member and a second conductive member. The lower cover is disposed on a circuit board. The upper cover is disposed on the lower cover. The sliding body passes through the upper cover and is configured to slide relative to the lower cover along a first direction. The elastic body is located between the lower cover and the upper cover, and the two ends of the elastic body respectively abut the sliding body and the lower cover. The first conductive member is disposed on the circuit board and is stationary relative to the lower cover. The second conductive member is disposed on the circuit board and is separated from the first conductive member. The sliding body drives the elastic body to elastically expand and contract along the first direction to generate a switching signal corresponding to the capacitance value between the first conductive member and the second conductive member, and the switching signal is associated with the dielectric constant between the first conductive member and the second conductive member.

[0016] In one or more embodiments of the present disclosure, a groove is provided between the first conductive element and the second conductive element, and the first conductive element is separated from the second conductive element by the groove.

[0017] In one or more embodiments of the present disclosure, the capacitive switch device further includes an insulating layer covering the first conductive member and the second conductive member.

[0023] In summary, in the capacitive switch device disclosed in the present invention, since the sliding member slides relative to the lower cover in the third direction through the elastic body, the user can repeatedly press the capacitive switch device as a keyboard key. In the capacitive switch device disclosed in the present invention, since the first conductive member is fixed on the circuit board and is stationary relative to the lower cover, and the second conductive member moves relative to the first conductive member as the sliding member slides, when the second conductive member moves relative to the first conductive member, a capacitance will be generated between the second conductive member and the first conductive member. In the capacitive switch device disclosed in the present invention, when the second conductive member moves relative to the first conductive member, the capacitance value between the second conductive member and the first conductive member will change with the overlapping area of ​​the second conductive member and the first conductive member or the distance between the second conductive member and the first conductive member, so that when the user presses the capacitive switch device, a switch signal associated with the overlapping area of ​​the second conductive member and the first conductive member or the distance between the second conductive member and the first conductive member can be generated. In the capacitive switch device disclosed in the present invention, when the first conductive member and the second conductive member are fixed on the circuit board, the user can generate a capacitance change by controlling the dielectric constant of the medium between the first conductive member and the second conductive member, so that when the user presses the capacitive switch device, a switch signal associated with the dielectric constant of the medium between the first conductive member and the second conductive member can be generated. In this way, compared with the traditional mechanical switch that can only generate an all-or-nothing switch signal of a pressed state and a non-pressed state, the capacitive switch device disclosed in the present invention can generate a switch signal between a pressed state and a non-pressed state, thereby increasing the flexibility and possibility of keyboard keys in the field of e-sports.

[0094] The following will disclose multiple embodiments of the present disclosure with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present disclosure. That is, in some embodiments of the present disclosure, these practical details are not necessary. In addition, in order to simplify the drawings, some known and commonly used structures and components will be depicted in a simple schematic manner in the drawings. The same reference numerals will be used to represent the same or similar components in all drawings.

[0095] The structures and functions of the components included in the capacitive switch device 100 of this embodiment and the connection relationship between the components will be described in detail below.

[0096] Please refer to Figure 1 . Figure 1 FIG. 1 is an exploded view of a capacitive switch device 100 according to an embodiment of the present disclosure. Figure 1As shown, in this embodiment, the capacitive switch device 100 includes an upper cover 110, a sliding body 120, an elastic body 130, a first conductive member 140, a second conductive member 150, a lower cover 160 and a circuit board 170. The upper cover 110, the sliding body 120, the elastic body 130, the first conductive member 140, the second conductive member 150, the lower cover 160 and the circuit board 170 are arranged substantially in a top-to-bottom direction. In this embodiment, the upper cover 110 has an opening OP110, and the sliding body 120 passes through the upper cover 110 through the opening OP110. The elastic body 130 is located between the upper cover 110 and the lower cover 160. The first conductive member 140 further includes a first fixed plate 142, a first conductive narrow plate 144A and a first conductive wide plate 144B. The first conductive narrow plate 144A is bent from the first fixed plate 142. The first conductive wide plate 144B extends parallel to the first conductive narrow plate 144A. In some embodiments, the first narrow conductive plate 144A and the first wide conductive plate 144B are parallel to the first fixed plate 142. The second conductive member 150 further includes a second fixed plate 152 and a second conductive plate 154. The second conductive plate 154 extends vertically from the second fixed plate 152. The lower cover 160 is combined with the circuit board 170. In some embodiments, the first narrow conductive plate 144A and the first wide conductive plate 144B are parallel to the second conductive plate 154. The circuit board 170 has an opening OP170, and a portion of the lower cover 160 is combined with the circuit board 170 through the opening OP170.

[0097] like Figure 1 As shown, in some embodiments, the first fixed plate 142 , the combination of the first conductive narrow plate 144A and the first conductive wide plate 144B, and the second conductive plate 154 extend parallel to each other and are arranged in a first direction (eg, direction X).

[0098] like Figure 1 As shown, in some embodiments, the first conductive narrow plate 144A has a width W144A in the second direction (e.g., direction Y), and the first conductive wide plate 144B has a width W144B in the second direction (e.g., direction Y). In some embodiments, the first conductive narrow plate 144A is located above the first conductive wide plate 144B, and the width W144A of the first conductive narrow plate 144A is smaller than the width W144B of the first conductive wide plate 144B.

[0099] In some other embodiments, the width W144A of the first conductive narrow plate 144A may gradually increase in the direction toward the first conductive wide plate 144B, and the width W144A of the first conductive narrow plate 144A is substantially equal to the width W144B of the first conductive wide plate 144B at the end connected to the first conductive wide plate 144B. Alternatively, in some other embodiments, the width W144A of the first conductive narrow plate 144A may gradually increase in the direction toward the first conductive wide plate 144B, and the width W144B of the first conductive wide plate 144B may gradually increase in the direction away from the first conductive narrow plate 144A, so that the first conductive narrow plate 144A and the first conductive wide plate 144B form a substantially triangular shape.

[0100] In some embodiments, the capacitive switch device 100 is configured to constitute a key of a keyboard, and is configured to generate a switch signal corresponding to two states of unpressed and pressed.

[0101] In some embodiments, the sliding body 120 is configured to receive a pressing operation by a user.

[0102] In some embodiments, the material of the upper cover 110 , the sliding body 120 , and the lower cover 160 may include, for example, plastic or other suitable insulating materials.

[0103] In some embodiments, the material of the elastic body 130 , the first conductive member 140 , and the second conductive member 150 may include, for example, metal or other suitable conductive materials.

[0104] In some embodiments, the elastic body 130 may be, for example, a spring or other suitable elastic materials.

[0105] In some embodiments, the circuit board 170 may be, for example, a printed circuit board (PCB).

[0106] Please refer to Figure 2 . Figure 2 FIG. 1 is a cross-sectional view of a capacitive switch device 100 according to an embodiment of the present disclosure. Figure 2As shown, in the present embodiment, the lower cover 160 is disposed on the circuit board 170. Specifically, the circuit board 170 has an opening OP170, and a portion of the lower cover 160 is combined with the circuit board 170 through the opening OP170. The upper cover 110 is disposed on the lower cover 160. Specifically, the upper cover 110 and the lower cover 160 are combined (for example, locked to each other) and form an accommodation space. The sliding body 120 passes through the upper cover 110 and is configured to slide relative to the lower cover 160 along a third direction (for example, direction Z). In some embodiments, a portion of the sliding body 120 is formed as a positioning shaft, and a portion of the lower cover 160 is formed as a positioning groove, and the sliding body 120 slides relative to the lower cover 160 through the structure of the positioning shaft and the positioning groove. The elastic body 130 is located in the above-mentioned accommodation space formed by the upper cover 110 and the lower cover 160, and the two ends of the elastic body 130 respectively abut the sliding body 120 and the lower cover 160. In some embodiments, the elastic body 130 is sleeved on the positioning shaft of the sliding body 120 and the positioning groove of the lower cover 160. The first conductive member 140 is disposed on the circuit board 170 and is stationary relative to the lower cover 160. The second conductive member 150 is connected to the sliding body 120 and moves relative to the first conductive member 140. The sliding body 120 drives the second conductive member 150 to move along a third direction (e.g., direction Z) to generate a switch signal corresponding to the capacitance value. The above capacitance value corresponds to the capacitance (Capacitance) formed between the first conductive member 140 and the second conductive member 150.

[0107] The following will describe in detail how the capacitive switch device 100 generates a switch signal.

[0108] Please refer to Figure 3 . Figure 3 FIG. 1 is a cross-sectional view of a capacitive switch device 100 in a non-pressed state S1 according to an embodiment of the present disclosure. Figure 3 As shown, in this embodiment, the sliding body 120 of the capacitive switch device 100 is configured to be pressed by the user along the pressing direction DP120. When the capacitive switch device 100 is in the unpressed state S1, the second conductive plate 154 is adjacent to the first conductive narrow plate 144A. Figure 3 As shown, there is a distance D1 between the second conductive plate 154 and the first conductive narrow plate 144A. Specifically, the distance D1 is the shortest distance between the second conductive plate 154 and the first conductive narrow plate 144A. Figure 3 As shown, the second conductive plate 154 and the first conductive narrow plate 144A have an overlapping area A1 in a first direction (eg, direction X).

[0109] Please refer to Figure 4 . Figure 4 FIG. 1 is a cross-sectional view of a capacitive switch device 100 in a pressed state S2 according to an embodiment of the present disclosure. Figure 4 As shown, in this embodiment, when the capacitive switch device 100 is in the pressing state S2, the sliding body 120 drives the second conductive plate 154 of the second conductive member 150 to move downward along the pressing direction DP120, so that the second conductive plate 154 is adjacent to the first conductive wide plate 144B. Figure 4 As shown, there is a distance D1 between the second conductive plate 154 and the first conductive wide plate 144B. In some embodiments, the distance D1 in the pressed state S2 is the same as the distance D1 in the unpressed state S1. In some other embodiments, the distance D1 in the pressed state S2 is less than the distance D1 in the unpressed state S1. Regardless of whether the distance D1 in the pressed state S2 is the same as the distance D1 in the unpressed state S1, the distance D1 must be a non-zero distance (i.e., the first conductive member 140 and the second conductive member 150 are not in contact). Figure 4 As shown, the second conductive plate 154 and the first conductive wide plate 144B have an overlapping area A2 in a first direction (eg, direction X).

[0110] In some other embodiments, an insulating material may be coated on the surface of the first conductive member 140 and the second conductive member 150. This can prevent the first conductive member 140 and the second conductive member 150 from being too close during the pressing process, which may cause the capacitance effect between the first conductive member 140 and the second conductive member 150 to fail. It should be noted that if the insulating material and the first conductive member 140 are regarded as one body and the insulating material and the second conductive member 150 are regarded as one body, the first conductive member 140 and the second conductive member 150 are "in contact with each other". If the insulating material is regarded as a component independent of the first conductive member 140 and the second conductive member 150, the first conductive member 140 is separated from the second conductive member 150 by the insulating material and "does not contact each other". Therefore, the two literal interpretations of "the first conductive member 140 and the second conductive member 150 are in contact with each other" and "the first conductive member 140 and the second conductive member 150 are not in contact with each other" should be regarded as equal.

[0111] Please also refer to Figure 1 , Figure 3 as well as Figure 4. Through the above-mentioned structural configuration, when the capacitive switch device 100 continuously changes between the unpressed state S1 and the pressed state S2, the capacitive switch device 100 can generate a switching signal between the unpressed state S1 and the pressed state S2. In detail, when the capacitive switch device 100 is in the unpressed state S1, there is a relatively small overlapping area A1 between the second conductive plate 154 and the first conductive narrow plate 144A, and a relatively small capacitance is generated. However, when the capacitive switch device 100 is in the pressed state S2, there is a relatively large overlapping area A2 between the second conductive plate 154 and the first conductive wide plate 144B, and a relatively large capacitance is generated. Since the capacitance value is positively correlated with the above-mentioned overlapping area, the capacitive switch device 100 can generate a switching signal associated with the overlapping area of ​​the first conductive member 140 and the second conductive member 150 in the first direction (for example, direction X).

[0112] The structures and functions of the components included in the capacitive switch device 200 of this embodiment and the connection relationship between the components will be described in detail below.

[0113] Please refer to Figure 5 . Figure 5 FIG. 2 is an exploded view of a capacitive switch device 200 according to an embodiment of the present disclosure. Figure 5 As shown, in this embodiment, the capacitive switch device 200 includes an upper cover 210, a sliding body 220, an elastic body 230, a first conductive member 240, a second conductive member 250 and a lower cover 260. In this embodiment, the capacitive switch device 200 also substantially includes a circuit board, but for the sake of simplicity, the relevant technical features of the circuit board will not be described here. The upper cover 210, the sliding body 220, the elastic body 230, the first conductive member 240, the second conductive member 250 and the lower cover 260 are arranged roughly in a top-to-bottom direction. In this embodiment, the upper cover 210 has an opening OP210 that matches the shape of the sliding body 220, and the sliding body 220 passes through the upper cover 210 through the opening OP210. The elastic body 230 is located between the upper cover 210 and the lower cover 260.

[0114] like Figure 5As shown, in this embodiment, the first conductive member 240 further includes a first fixed plate 242 and a first conductive plate 244 connected to the first fixed plate 242. The first conductive plate 244 further includes a first conductive sub-plate 244A, a first connecting plate 244B and a first conductive sub-plate 244C. The first conductive sub-plate 244A and the first conductive sub-plate 244C are connected to the first fixed plate 242, and the first conductive sub-plate 244A extends parallel to the first conductive sub-plate 244C. The second conductive member 250 further includes a second fixed plate 252 and a second conductive plate 254 connected to the second fixed plate 252. The second conductive plate 254 further includes a second conductive sub-plate 254A, a second connecting plate 254B and a second conductive sub-plate 254C. The second conductive sub-plate 254A and the second conductive sub-plate 254C are connected to the second fixed plate 252, and the second conductive sub-plate 254A extends parallel to the second conductive sub-plate 254C.

[0115] like Figure 5 As shown, in some embodiments, the first conductive sub-plate 244A, the first conductive sub-plate 244C, the second conductive sub-plate 254A, and the second conductive sub-plate 254C extend parallel to each other and are arranged in a first direction (eg, direction X).

[0116] like Figure 5 As shown, in some embodiments, when viewed from above along a third direction (for example, direction Z), the combination of the first conductive sub-plate 244A, the first connecting plate 244B and the first conductive sub-plate 244C presents an inverted U shape, and the combination of the second conductive sub-plate 254A, the second connecting plate 254B and the second conductive sub-plate 254C presents an inverted U shape.

[0117] In some embodiments, the material of the upper cover 210 , the sliding body 220 , and the lower cover 260 may include, for example, plastic or other suitable insulating materials.

[0118] In some embodiments, the material of the elastic body 230 , the first conductive member 240 , and the second conductive member 250 may include, for example, metal or other suitable conductive materials.

[0119] In some embodiments, the elastic body 230 may be, for example, a spring or other suitable elastic materials.

[0120] Please refer to Figure 6 . Figure 6 FIG. 2 is a cross-sectional view of a capacitive switch device 200 according to an embodiment of the present disclosure. Figure 6As shown, in this embodiment, the lower cover 260 is disposed on the circuit board. The upper cover 210 is disposed on the lower cover 260. Specifically, the upper cover 210 and the lower cover 260 are combined (for example, locked to each other) to form an accommodation space. The sliding body 220 passes through the upper cover 210 and is configured to slide relative to the lower cover 260 along a third direction (for example, direction Z). The elastic body 230 is located in the above-mentioned accommodation space formed by the upper cover 210 and the lower cover 260, and the two ends of the elastic body 230 respectively abut the sliding body 220 and the lower cover 260. In some embodiments, the two ends of the elastic body 230 respectively abut the second fixing plate 252 and the lower cover 260. The first conductive member 240 is disposed on the circuit board and is stationary relative to the lower cover 260. The second conductive member 250 is connected to the sliding body 220 and moves relative to the first conductive member 240. The sliding body 220 drives the second conductive member 250 to move along the third direction (for example, direction Z) to generate a switch signal corresponding to the capacitance value. The above capacitance value corresponds to the capacitance formed between the first conductive element 240 and the second conductive element 250 .

[0121] The following will describe in detail how the capacitive switch device 200 generates a switch signal.

[0122] Please refer to Figure 7 . Figure 7 FIG. 2 is a cross-sectional view of a capacitive switch device 200 in a non-pressed state S3 according to an embodiment of the present disclosure. Figure 7 As shown, in this embodiment, the sliding body 220 of the capacitive switch device 200 is configured for the user to press along the pressing direction DP220. When the capacitive switch device 200 is in the unpressed state S3, the first conductive sub-plate 244A is located between the second conductive sub-plate 254A and the second conductive sub-plate 254C, and the second conductive sub-plate 254C is located between the first conductive sub-plate 244A and the first conductive sub-plate 244C. Figure 7 As shown, there is a distance D2 between the second conductive sub-plate 254A and the first conductive sub-plate 244A, a distance D2 between the first conductive sub-plate 244A and the second conductive sub-plate 254C, and a distance D2 between the second conductive sub-plate 254C and the first conductive sub-plate 244C. Specifically, the distance D2 is the shortest distance between any two adjacent conductive sub-plates. Figure 7 As shown, the first conductive sub-plate 244A, the first conductive sub-plate 244C, the second conductive sub-plate 254A, and the second conductive sub-plate 254C have an overlapping area A3 in a first direction (eg, direction X).

[0123] Please refer to Figure 8 . Figure 8 FIG. 2 is a cross-sectional view of a capacitive switch device 200 in a pressed state S4 according to an embodiment of the present disclosure. Figure 8 As shown, in the present embodiment, when the capacitive switch device 200 is in the pressed state S4, the sliding body 220 drives the second conductive sub-plate 254A and the second conductive sub-plate 254C of the second conductive member 250 to move downward along the pressing direction DP220, so that when the second conductive member 250 abuts against the lower cover 260, there is still a distance D2 between the second conductive sub-plate 254A and the first conductive sub-plate 244A, there is still a distance D2 between the first conductive sub-plate 244A and the second conductive sub-plate 254C, and there is still a distance D2 between the second conductive sub-plate 254C and the first conductive sub-plate 244C. In some embodiments, the distance D2 in the pressed state S4 is the same as the distance D2 in the unpressed state S3. Regardless of whether the distance D2 in the pressed state S4 is the same as the distance D2 in the unpressed state S3, the distance D2 must be a non-zero distance (that is, the first conductive member 240 and the second conductive member 250 are not in contact). As shown in FIG. Figure 8 As shown, the first conductive sub-plate 244A, the first conductive sub-plate 244C, the second conductive sub-plate 254A, and the second conductive sub-plate 254C have an overlapping area A4 in a first direction (eg, direction X).

[0124] In some other embodiments, an insulating material may be coated on the surface of the first conductive member 240 and the second conductive member 250. This can prevent the first conductive member 240 and the second conductive member 250 from being too close to each other during the pressing process, which may cause the capacitance effect between the first conductive member 240 and the second conductive member 250 to fail. It should be noted that if the insulating material and the first conductive member 240 are regarded as one body and the insulating material and the second conductive member 250 are regarded as one body, the first conductive member 240 and the second conductive member 250 are "in contact with each other". If the insulating material is regarded as a component independent of the first conductive member 240 and the second conductive member 250, the first conductive member 240 is separated from the second conductive member 250 by the insulating material and "does not contact each other". Therefore, the two literal interpretations of "the first conductive member 240 and the second conductive member 250 are in contact with each other" and "the first conductive member 240 and the second conductive member 250 are not in contact with each other" should be regarded as equal.

[0125] Please also refer to Figure 5 , Figure 7 as well as Figure 8. Through the above-mentioned structural configuration, when the capacitive switch device 200 continuously changes between the unpressed state S3 and the pressed state S4, the capacitive switch device 200 can generate a switch signal between the unpressed state S3 and the pressed state S4. In detail, when the capacitive switch device 200 is in the unpressed state S3, the first conductive sub-plate 244A, the first conductive sub-plate 244C, the second conductive sub-plate 254A and the second conductive sub-plate 254C have a relatively small overlap area A1 and generate a relatively small capacitance. However, when the capacitive switch device 200 is in the pressed state S4, the first conductive sub-plate 244A, the first conductive sub-plate 244C, the second conductive sub-plate 254A and the second conductive sub-plate 254C have a relatively large overlap area A2 and generate a relatively large capacitance. Since the capacitance value is positively correlated with the overlap area, the capacitive switch device 200 can generate a switch signal associated with the overlap area of ​​the first conductive sub-plate 244A, the first conductive sub-plate 244C, the second conductive sub-plate 254A and the second conductive sub-plate 254C in a first direction (eg, direction X).

[0126] The structures and functions of the components included in the capacitive switch device 300 of this embodiment and the connection relationship between the components will be described in detail below.

[0127] Please refer to Fig. 9 . Fig. 9 FIG. 1 is an exploded view of a capacitive switch device 300 according to an embodiment of the present disclosure. Fig. 9 As shown, in this embodiment, the capacitive switch device 300 includes an upper cover 310, a sliding body 320, an elastic body 330, a first conductive member 340, a second conductive member 350 and a lower cover 360. In this embodiment, the capacitive switch device 300 also substantially includes a circuit board, but for the sake of simplicity, the relevant technical features of the circuit board will not be described here. The upper cover 310, the sliding body 320, the elastic body 330, the first conductive member 340, the second conductive member 350 and the lower cover 360 are arranged roughly in a top-to-bottom direction. In this embodiment, the upper cover 310 has an opening OP310, and the sliding body 320 passes through the upper cover 310 through the opening OP310. The elastic body 330 is located between the upper cover 310 and the lower cover 360.

[0128] like Fig. 9As shown, in this embodiment, the first conductive member 340 further includes a first fixed plate 342 and a first conductive plate 344 connected to the first fixed plate 342. The first fixed plate 342 is disposed on the circuit board. The first conductive plate 344 is connected to the first fixed plate 342, and the first conductive plate 344 extends parallel to the first fixed plate 342. The second conductive member 350 further includes a second swing plate 352, a positioning column 352A, and a second conductive plate 354 connected to the second swing plate 352. The positioning column 352A is disposed on the second swing plate 352. In some embodiments, the second conductive plate 354 extends substantially vertically from the second swing plate 352.

[0129] like Fig. 9 As shown, in this embodiment, the capacitive switch device 300 further includes a spacer SG located between the first conductive plate 344 and the second conductive plate 354 .

[0130] In some embodiments, the material of the upper cover 310 , the sliding body 320 , and the lower cover 360 may include, for example, plastic or other suitable insulating materials.

[0131] In some embodiments, the material of the elastic body 330 and the first conductive member 340 may include, for example, metal or other suitable conductive materials.

[0132] In some embodiments, the elastic body 330 may be, for example, a spring or other suitable elastic materials.

[0133] In some embodiments, the material of the second conductive member 350 may include, for example, conductive plastic or other suitable conductive materials.

[0134] In some embodiments, the spacer SG may be, for example, sponge, foam, or other suitable spacer materials.

[0135] Please refer to Fig.10 . Fig.10 FIG. 2 is a cross-sectional view of a capacitive switch device 300 according to an embodiment of the present disclosure. Fig.10As shown, in this embodiment, the lower cover 360 is disposed on the circuit board. The upper cover 310 is disposed on the lower cover 360. Specifically, the upper cover 310 and the lower cover 360 are combined (for example, locked to each other) and form an accommodation space. The sliding body 320 passes through the upper cover 310 and is configured to slide relative to the lower cover 360 along a third direction (for example, direction Z). The elastic body 330 is located in the above-mentioned accommodation space formed by the upper cover 310 and the lower cover 360. The elastic body 330 is sleeved on the positioning column 352A, and the two ends of the elastic body 330 respectively abut the sliding body 320 and the second swing plate 352. The first conductive member 340 is disposed on the circuit board and is stationary relative to the lower cover 360. The second conductive member 350 is connected to the sliding body 320 through the elastic body 330 and moves relative to the first conductive member 340. More specifically, the second conductive member 350 swings relative to the first conductive member 340. In some embodiments, the spacer SG is disposed on the second conductive plate 354. The sliding body 320 drives the second conductive member 350 to rotate along the third direction (e.g., direction Z) with a rotation axis parallel to the second direction (e.g., direction Y) and causes the second conductive plate 354 to swing toward the first conductive plate 344 to generate a switch signal corresponding to the capacitance value. The capacitance value corresponds to the capacitance formed between the first conductive member 340 and the second conductive member 350.

[0136] The following will describe in detail how the capacitive switch device 300 generates a switch signal.

[0137] Please refer to Fig.11 . Fig.11 FIG. 4 is a cross-sectional view of a capacitive switch device 300 in a non-pressed state S5 according to an embodiment of the present disclosure. Fig.11 As shown, in this embodiment, the sliding body 320 of the capacitive switch device 300 is configured for the user to press along the pressing direction DP320. When the capacitive switch device 300 is in the unpressed state S5, there is a distance D3A between the first conductive plate 344 and the second conductive plate 354. In detail, the distance D3A is the shortest distance between the first conductive plate 344 and the second conductive plate 354. Fig.11 As shown, the first conductive plate 344 and the second conductive plate 354 have an overlapping area A5 in a first direction (eg, direction X). In some embodiments, the spacer SG has a thickness TSG.

[0138] Please refer to Fig.12 . Fig.12 FIG. 4 is a cross-sectional view of a capacitive switch device 300 in a pressed state S6 according to an embodiment of the present disclosure. Fig.12As shown, in this embodiment, when the capacitive switch device 300 is in the pressed state S6, the sliding body 320 drives the second conductive member 350 to rotate along the third direction (for example, direction Z) with a rotation axis parallel to the second direction (for example, direction Y), and causes the second conductive plate 354 to rotate along the third direction (for example, direction Z). Fig.11 The swing direction SW350 shown moves toward the first conductive plate 344, so that when the spacer SG abuts the first conductive member 340, there is a distance D3B between the first conductive plate 344 and the second conductive plate 354. In some embodiments, the distance D3B in the pressed state S6 is substantially equal to the thickness TSG of the spacer SG. In some embodiments, the distance D3B in the pressed state S6 is less than the distance D3A in the unpressed state S5, and the distance D3A and the distance D3B must be non-zero distances (i.e., the first conductive member 340 is not in contact with the second conductive member 350). More specifically, since the spacer SG is disposed on the second conductive plate 354 and is located between the first conductive plate 344 and the second conductive plate 354, it can be ensured that the first conductive plate 344 and the second conductive plate 354 are not in contact. As Fig.12 As shown, the first conductive plate 344 and the second conductive plate 354 have an overlapping area A6 in a first direction (eg, direction X).

[0139] In some other embodiments, an insulating material may be coated on the surface of the first conductive member 340 and the second conductive member 350. This can prevent the first conductive member 340 and the second conductive member 350 from being too close during the pressing process, which may cause the capacitance effect between the first conductive member 340 and the second conductive member 350 to fail. It should be noted that if the insulating material and the first conductive member 340 are regarded as one body and the insulating material and the second conductive member 350 are regarded as one body, the first conductive member 340 and the second conductive member 350 are "in contact with each other". If the insulating material is regarded as a component independent of the first conductive member 340 and the second conductive member 350, the first conductive member 340 is separated from the second conductive member 350 by the insulating material and "does not contact each other". Therefore, the two literal interpretations of "the first conductive member 340 and the second conductive member 350 are in contact with each other" and "the first conductive member 340 and the second conductive member 350 are not in contact with each other" should be regarded as equal.

[0140] Please also refer to Fig. 9 , Fig.11 as well as Fig.12. Through the aforementioned structural configuration, when the capacitive switch device 300 continuously changes between the unpressed state S5 and the pressed state S6, the capacitive switch device 300 can generate a switch signal between the unpressed state S5 and the pressed state S6. In detail, when the capacitive switch device 300 is in the unpressed state S5, there is a relatively large distance D3A between the first conductive plate 344 and the second conductive plate 354, resulting in a relatively small capacitance. However, when the capacitive switch device 300 is in the pressed state S6, there is a relatively small distance D3B between the first conductive plate 344 and the second conductive plate 354, resulting in a relatively large capacitance. Since the capacitance value is negatively correlated with the above-mentioned distance, the capacitive switch device 300 can generate a switch signal associated with the distance between the first conductive member 340 and the second conductive member 350.

[0141] The structures and functions of the components included in the capacitive switch device 400 of this embodiment and the connection relationship between the components are described in detail below.

[0142] Please refer to Fig.13 . Fig.13 FIG. 4 is an exploded view of a capacitive switch device 400 according to an embodiment of the present disclosure. Fig.13 As shown, in this embodiment, the capacitive switch device 400 includes an upper cover 410, a sliding body 420, an elastic body 430, a first conductive member 440, a second conductive member 450 and a lower cover 460. In this embodiment, the capacitive switch device 400 also substantially includes a circuit board, but for the sake of simplicity, the relevant technical features of the circuit board will not be described here. The upper cover 410, the sliding body 420, the elastic body 430, the first conductive member 440, the second conductive member 450 and the lower cover 460 are arranged roughly in a top-to-bottom direction. In this embodiment, the upper cover 410 has an opening OP410, and the sliding body 420 passes through the upper cover 410 through the opening OP410. The elastic body 430 is located between the upper cover 410 and the lower cover 460.

[0143] like Fig.13 As shown, in this embodiment, the first conductive member 440 further includes a first fixing plate 442 and a first conductive plate 444 connected to the first fixing plate 442. The first fixing plate 442 is disposed on the circuit board. The first conductive plate 444 is connected to the first fixing plate 442, and the first conductive plate 444 extends parallel to the first fixing plate 442. The second conductive member 450 extends parallel to the first conductive plate 444.

[0144] like Fig.13As shown, in this embodiment, the capacitive switch device 400 further includes a flexible body RB located between the first conductive member 440 and the second conductive member 450. The flexible body RB is configured to pass through the first conductive member 440. In detail, the flexible body RB includes a first convex portion B1 and a plurality of second convex portions B2. The first convex portion B1 is located at the center of the flexible body RB, and the plurality of second convex portions B2 surround the first convex portion B1. The first conductive plate 444 has a first through hole TH1 and a second through hole TH2 respectively disposed corresponding to the first convex portion B1 and the second convex portion B2.

[0145] In some embodiments, the material of the upper cover 410 , the sliding body 420 , and the lower cover 460 may include, for example, plastic or other suitable insulating materials.

[0146] In some embodiments, the materials of the elastic body 430 , the first conductive member 440 , and the second conductive member 450 may include, for example, metal or other suitable conductive materials.

[0147] In some embodiments, the elastic body 430 may be, for example, a spring or other suitable elastic materials.

[0148] In some embodiments, the flexible body RB may be, for example, rubber or other suitable flexible materials.

[0149] Please refer to Fig.14 . Fig.14 FIG. 4 is a cross-sectional view of a capacitive switch device 400 according to an embodiment of the present disclosure. Fig.14As shown, in the present embodiment, the lower cover 460 is disposed on the circuit board. The upper cover 410 is disposed on the lower cover 460. Specifically, the upper cover 410 and the lower cover 460 are combined (for example, locked to each other) and form an accommodation space. The sliding body 420 passes through the upper cover 410 and is configured to slide relative to the lower cover 460 along a third direction (for example, direction Z). The elastic body 430 is located in the above-mentioned accommodation space formed by the upper cover 410 and the lower cover 460. The two ends of the elastic body 430 respectively abut the sliding body 420 and the second conductive member 450. The first conductive member 440 is disposed on the circuit board and is stationary relative to the lower cover 460. The second conductive member 450 moves relative to the first conductive member 440 through the elastic body 430. Specifically, the second conductive member 450 moves relative to the first conductive member 440 by the elastic restoring force of the elastic body 430 against the flexible body RB. In some embodiments, the flexible body RB is disposed on the lower cover 460 and is located between the lower cover 460 and the second conductive member 450, and the first protrusion B1 of the flexible body RB abuts against the second conductive member 450. The sliding body 420 drives the second conductive member 450 along a third direction (e.g., direction Z) to move relative to the first conductive member 440 to generate a switch signal corresponding to the capacitance value. The above capacitance value corresponds to the capacitance (Capacitance) formed between the first conductive member 440 and the second conductive member 450.

[0150] How the capacitive switch device 400 generates a switch signal will be described in detail below.

[0151] Please refer to Fig.15 . Fig.15 FIG. 4 is a cross-sectional view of a capacitive switch device 400 in a non-pressed state S7 according to an embodiment of the present disclosure. Fig.15 As shown, in this embodiment, the sliding body 420 of the capacitive switch device 400 is configured for the user to press along the pressing direction DP420. When the capacitive switch device 400 is in the unpressed state S7, there is a distance D4A between the first conductive plate 444 and the second conductive member 450. In detail, the distance D4A is the shortest distance between the first conductive plate 444 and the second conductive member 450. Fig.15 As shown, the first conductive plate 444 and the second conductive member 450 have an overlapping area A7 in the third direction (eg, direction Z). In some embodiments, when the capacitive switch device 400 is in the unpressed state S7 , a buffer space is provided between the first protrusion B1 and the lower cover 460 .

[0152] Please refer to Fig.16 . Fig.16 FIG. 4 is a cross-sectional view of a capacitive switch device 400 in a pressed state S8 according to an embodiment of the present disclosure. Fig.16As shown, in this embodiment, when the capacitive switch device 400 is in the pressed state S8, the sliding body 420 drives the second conductive member 450 to move relative to the first conductive plate 444 through the elastic body 430 along the third direction (for example, direction Z), so that when the flexible body RB pressed by the second conductive member 450 presses down against the lower cover 460, there is a distance D4B between the first conductive plate 444 and the second conductive member 450. In some embodiments, the distance D4B in the pressed state S8 is less than the distance D4A in the unpressed state S7, and the distance D4A and the distance D4B must be non-zero distances (that is, the first conductive member 440 is not in contact with the second conductive member 450). Fig.16 As shown, the first conductive plate 444 and the second conductive plate 354 have an overlapping area A8 in a first direction (eg, direction X).

[0153] In some other embodiments, the user may over-press the sliding body 420, so that the flexible body RB pushed downward by the second conductive member 450 is further compressed, so that the first conductive member 440 and the second conductive member 450 are in contact and the capacitance effect fails. In this case, an insulating material can be coated on the surface of the first conductive member 440 and the second conductive member 450. This can avoid that the capacitance effect between the first conductive member 440 and the second conductive member 450 can still be achieved when the sliding body 420 is over-pressed. It should be noted that if the insulating material is regarded as a whole with the first conductive member 440 and the insulating material is regarded as a whole with the second conductive member 450, the first conductive member 440 and the second conductive member 450 are "in contact with each other". If the insulating material is regarded as a component independent of the first conductive member 440 and the second conductive member 450, the first conductive member 440 is separated from the second conductive member 450 by the insulating material and "does not contact each other". Therefore, the two literal interpretations of “the first conductive element 440 and the second conductive element 450 are in contact with each other” and “the first conductive element 440 and the second conductive element 450 are not in contact with each other” should be considered equal.

[0154] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Fig. 9 , Fig.10 , Fig.13 as well as Fig.14As shown, the elastic body 130, the elastic body 230, the elastic body 330 and the elastic body 430 each include a soldering foot disposed at the bottom thereof, and the elastic body 130, the elastic body 230, the elastic body 330 and the elastic body 430 are soldered to a circuit board (not shown) through the above-mentioned soldering foot. In some other embodiments, the capacitive switch device 100, the capacitive switch device 200, the capacitive switch device 300 and the capacitive switch device 400 each further include a metal plate (not shown) with a soldering foot located below the elastic body 130, the elastomer 230, the elastomer 330 and the elastomer 430 and soldered to a circuit board (not shown), while the elastic body 130, the elastomer 230, the elastomer 330 and the elastomer 430 do not have the above-mentioned soldering foot.

[0155] Please also refer to Fig.13 , Fig.15 as well as Fig.16 . Through the aforementioned structural configuration, when the capacitive switch device 400 continuously changes between the unpressed state S7 and the pressed state S8, the capacitive switch device 400 can generate a switch signal between the unpressed state S7 and the pressed state S8. In detail, when the capacitive switch device 400 is in the unpressed state S7, there is a relatively large distance D4A between the first conductive plate 444 and the second conductive member 450, resulting in a relatively small capacitance. However, when the capacitive switch device 400 is in the pressed state S8, there is a relatively small distance D4B between the first conductive plate 444 and the second conductive member 450, resulting in a relatively large capacitance. Since the capacitance value is negatively correlated with the above-mentioned distance, the capacitive switch device 400 can generate a switch signal associated with the distance between the first conductive member 440 and the second conductive member 450.

[0156] The structures and functions of the components included in the capacitive switch device 500 of this embodiment and the connection relationship between the components will be described in detail below.

[0157] Please refer to Fig.17 . Fig.17 FIG. 5 is an exploded view of a capacitive switch device 500 according to an embodiment of the present disclosure. Fig.17 As shown, in this embodiment, the capacitive switch device 500 includes an upper cover 510, a sliding body 520, an elastic body 530, a first conductive member 540, a second conductive member 550, a lower cover 560, and a circuit board 570. The upper cover 510, the sliding body 520, the elastic body 530, the lower cover 560, and the circuit board 570 are arranged substantially in a top-to-bottom direction. In this embodiment, the upper cover 510 has an opening OP510, and the sliding body 520 passes through the upper cover 510 through the opening OP510. The elastic body 530 is located between the upper cover 510 and the lower cover 560.

[0158] like Fig.17 As shown, in this embodiment, the first conductive member 540 and the second conductive member 550 are disposed on the circuit board 570, and the first conductive member 540 is separated from the second conductive member 550. Specifically, the first conductive member 540 and the second conductive member 550 are not in contact, so that a capacitive effect can be generated between the first conductive member 540 and the second conductive member 550. Fig.17 As shown, a trench T is defined between the first conductive member 540 and the second conductive member 550 .

[0159] In some embodiments, the materials of the upper cover 510 , the sliding body 520 , and the lower cover 560 may include, for example, plastic or other suitable insulating materials.

[0160] In some embodiments, the material of the elastic body 530 , the first conductive member 540 , and the second conductive member 550 may include, for example, metal or other suitable conductive materials.

[0161] In some embodiments, the elastic body 530 may be, for example, a spring or other suitable elastic material. In some embodiments, the elastic body 530 may be, for example, a spiral spring or other suitable spring.

[0162] In some embodiments, the dielectric flexible body HKRB may be a dielectric material including, for example, a high-k material. In some embodiments, the dielectric flexible body HKRB may be doped with, for example, barium titanate (BaTiO 3 ) or other suitable high-k materials.

[0163] Please refer to Fig.18 . Fig.18 FIG. 5 is a cross-sectional view of a capacitive switch device 500 according to an embodiment of the present disclosure. Fig.18 As shown, in the present embodiment, the lower cover 560 is disposed on the circuit board 570. The upper cover 510 is disposed on the lower cover 560. Specifically, the upper cover 510 and the lower cover 560 are combined (for example, locked to each other) and form a receiving space. The sliding body 520 passes through the upper cover 510 and is configured to slide relative to the lower cover 560 along a third direction (for example, direction Z). The elastic body 530 is located in the above-mentioned receiving space formed by the upper cover 510 and the lower cover 560. The two ends of the elastic body 530 respectively abut the sliding body 520 and the lower cover 560. The sliding body 520 moves relative to the lower cover 560 through the elastic body 530. In some embodiments, the above-mentioned dielectric flexible body HKRB is disposed on the lower cover 560 and is located between the bottom of the lower cover 560 and the elastic body 530.

[0164] like Fig.18As shown, the lower cover 560 has an opening OP560A, an opening OP560B and abutting surface 560s. The opening OP560A is located at the bottom of the lower cover 560, and the opening OP560A exposes the groove T, the first conductive member 540 and the second conductive member 550. The opening OP560B is located above the opening OP560A, and the opening OP560B is connected to the opening OP560A. In some embodiments, the opening OP560A is located within the range of the opening OP560B. In some embodiments, the diameter of the opening OP560B is larger than the diameter of the opening OP560A. The butting surface 560s is connected between the opening OP560A and the opening OP560B. Fig.18 As shown, the edge of the dielectric flexible body HKRB abuts against the abutment surface 560s of the lower cover 560. Fig.18 As shown, in some embodiments, the edge of the dielectric flexure HKRB matches the contour of the opening OP560B.

[0165] The sliding body 520 drives the dielectric flexible body HKRB to move relative to the first conductive member 540 and the second conductive member 550 along a third direction (eg, direction Z) to generate a switch signal corresponding to the capacitance value formed between the first conductive member 540 and the second conductive member 550 .

[0166] How the capacitive switch device 500 generates a switch signal will be described in detail below.

[0167] Please refer to Fig.19 . Fig.19 FIG. 5 is a cross-sectional view of a capacitive switch device 500 in a non-pressed state S9 according to an embodiment of the present disclosure. Fig.19 As shown, in this embodiment, the sliding body 520 of the capacitive switch device 500 is configured for the user to press along the pressing direction DP520. When the capacitive switch device 500 is in the unpressed state S9, one end of the elastic body 530 abuts against the lower cover 560 by abutting against the dielectric flexible body HKRB. In detail, one end of the elastic body 530 abuts against the dielectric flexible body HKRB and abuts against the abutting surface 560s of the lower cover 560. Fig.19 As shown, when the capacitive switch device 500 is in the unpressed state S9 , the center of the dielectric flexible body HKRB protrudes away from the circuit board 570 , and the dielectric flexible body HKRB does not contact the first conductive member 540 and the second conductive member 550 .

[0168] Please refer to Fig. 20 . Fig. 20 According to one embodiment of the present disclosure, Fig.19is a partial enlarged view of the capacitive switch device 500 in the unpressed state S9. Specifically, the change in capacitance formed between the first conductive member 540 and the second conductive member 550 is associated with the change in the dielectric constant of the medium between the first conductive member 540 and the second conductive member 550. In detail, when the dielectric constant of the medium between the first conductive member 540 and the second conductive member 550 remains unchanged, the capacitance formed between the first conductive member 540 and the second conductive member 550 also remains constant. When the dielectric constant of the medium between the first conductive member 540 and the second conductive member 550 increases, the capacitance formed between the first conductive member 540 and the second conductive member 550 will increase accordingly, thereby generating a switching signal. For example, when the capacitive switch device 500 is in the unpressed state S9, since the entire device is in a stationary state, the capacitance formed between the first conductive member 540 and the second conductive member 550 remains constant.

[0169] Please refer to Fig.21 . Fig.21 FIG. 5 is a cross-sectional view of a capacitive switch device 500 in a pressed state S10 according to an embodiment of the present disclosure. Fig.21 As shown, in this embodiment, when the capacitive switch device 500 is in the pressed state S10, the sliding body 520 drives the dielectric flexible body HKRB to move relative to the first conductive member 540 and the second conductive member 550 through the elastic body 530 along the third direction (for example, direction Z). When the dielectric flexible body HKRB abutted by the elastic body 530 presses downward against the lower cover 560 (that is, from the unpressed state S9 to the pressed state S10), the elastic body 530 having multiple turns presses against the dielectric flexible body HKRB in sequence from the outermost turn to the inner turn, so that the center of the dielectric flexible body HKRB gradually sinks toward the first conductive member 540 and the second conductive member 550.

[0170] In some other embodiments, the user may over-press the sliding body 520 , so that the dielectric flexible body HKRB pushed downward by the elastic body 530 is further pressed downward, so that a portion of the dielectric flexible body HKRB falls into the range of the groove T.

[0171] Please refer to Fig. 22 . Fig. 22 According to one embodiment of the present disclosure, Fig.21 5 is a partial enlarged view of the capacitive switch device 500 in the pressed state S10. Fig. 22As shown, when the capacitive switch device 500 is switched from the unpressed state S9 to the pressed state S10, the dielectric flexible body HKRB comprising, for example, a high dielectric constant material approaches the first conductive member 540 and the second conductive member 550, so that the dielectric constant of the medium between the first conductive member 540 and the second conductive member 550 increases, and thus the capacitance formed between the first conductive member 540 and the second conductive member 550 also increases, thereby generating a switching signal.

[0172] Please also refer to Fig.17 , Fig.19 as well as Fig.21 . Through the aforementioned structural configuration, when the capacitive switch device 500 continuously changes between the unpressed state S9 and the pressed state S10, the capacitive switch device 500 can generate a switch signal between the unpressed state S9 and the pressed state S10. In detail, when the capacitive switch device 500 is in the unpressed state S9, the dielectric flexible body HKRB is separated from the first conductive member 540 and the second conductive member 550, respectively, so the medium between the first conductive member 540 and the second conductive member 550 is mainly affected by air, thereby generating a relatively small capacitance. However, when the capacitive switch device 500 is in the pressed state S10, the dielectric flexible body HKRB approaches the first conductive member 540 and the second conductive member 550, so the medium between the first conductive member 540 and the second conductive member 550 is more affected by the dielectric flexible body HKRB including, for example, a high dielectric constant material, thereby generating a relatively large capacitance. Since the capacitance value is positively correlated with the dielectric constant, the capacitive switch device 500 can generate a switching signal associated with the dielectric constant of the medium between the first conductive element 540 and the second conductive element 550 .

[0173] The structures and functions of the components included in the capacitive switch device 600 of this embodiment and the connection relationship between the components will be described in detail below.

[0174] Please refer to Fig.23 as well as Fig.24 . Fig.23 as well as Fig.24 They are respectively an exploded view and a cross-sectional schematic diagram of a capacitive switch device 600 according to an embodiment of the present disclosure. Fig.23 as well as Fig.24As shown, in this embodiment, the capacitive switch device 600 includes an upper cover 610, a sliding body 620, an elastic body 630, a first conductive member 640, a second conductive member 650, a lower cover 660, and a circuit board 670. The upper cover 610, the sliding body 620, the elastic body 630, the lower cover 660, and the circuit board 670 are arranged substantially in a top-to-bottom direction. In this embodiment, the upper cover 610 has an opening OP610, and the sliding body 620 passes through the upper cover 610 through the opening OP610. The elastic body 630 is located between the upper cover 610 and the lower cover 660. As shown in FIG. Fig.24 As shown, the lower cover 660 has an opening OP660A, an opening OP660B and abutting surface 660s. Since the structural configuration of the capacitive switch device 600 is substantially similar to that of the capacitive switch device 500, they will not be described one by one here. The difference between the capacitive switch device 600 and the capacitive switch device 500 is that the capacitive switch device 600 does not include a dielectric flexible body HKRB.

[0175] The following will describe in detail how the capacitive switch device 600 generates a switch signal.

[0176] Please refer to Fig.25 . Fig.25 FIG. 6 is a cross-sectional view of a capacitive switch device 600 in a non-pressed state S11 according to an embodiment of the present disclosure. Fig.25 As shown, in this embodiment, the capacitive switch device 600 further includes an insulating layer 680. The insulating layer 680 covers at least the first conductive member 640 and the second conductive member 650. In some embodiments, the insulating layer 680 covers the entire surface of the circuit board 670 and fills the groove T. In some embodiments, the insulating layer 680 is located between the lower cover 660 and the circuit board 670. Fig.25 As shown, in this embodiment, the sliding body 620 of the capacitive switch device 600 is configured for the user to press along the pressing direction DP620. When the capacitive switch device 600 is in the unpressed state S11, one end of the elastic body 630 abuts against the lower cover 660. In detail, one end of the elastic body 630 abuts against the abutting surface 660s of the lower cover 660.

[0177] Please refer to Fig.26 . Fig.26 According to one embodiment of the present disclosure, Fig.256 is a partial enlarged view of the capacitive switch device 600 in the unpressed state S11. Specifically, the amount of change in capacitance formed between the first conductive member 640 and the second conductive member 650 is associated with the amount of change in the dielectric constant of the medium between the first conductive member 640 and the second conductive member 650. For example, when the capacitive switch device 600 is in the unpressed state S11, the capacitance formed between the first conductive member 640 and the second conductive member 650 remains constant because the entire device is in a stationary state.

[0178] Please refer to Fig. 27 . Fig. 27 FIG. 6 is a cross-sectional view of a capacitive switch device 600 in a pressed state S12 according to an embodiment of the present disclosure. Fig. 27 As shown, in this embodiment, when the capacitive switch device 600 is in the pressed state S12, the sliding body 620 compresses the elastic body 630 along the third direction (for example, direction Z). When the elastic body 630 is compressed (that is, from the unpressed state S11 to the pressed state S12), the elastic body 630 is separated from the first conductive member 640 and the second conductive member 650 by the insulating layer 680, so that the elastic body 630 is not in direct contact with the first conductive member 640 and the second conductive member 650. When the elastic body 630 is compressed, the elastic body 630 having multiple turns sequentially abuts against the abutting surface 660s and the circuit board 670 from the outermost turn to the inner turn.

[0179] Please refer to Fig.28 . Fig.28 According to one embodiment of the present disclosure, Fig. 27 6 is a partial enlarged view of the capacitive switch device 600 in the pressed state S12. Fig.28 As shown, when the capacitive switch device 600 is switched from the unpressed state S11 to the pressed state S12, since several turns of the elastic body 630 approach the first conductive member 640 and the second conductive member 650, the dielectric constant of the medium between the first conductive member 640 and the second conductive member 650 increases, and thus the capacitance formed between the first conductive member 640 and the second conductive member 650 also increases, thereby generating a switching signal.

[0180] Please also refer to Fig.23 , Fig.25 as well as Fig. 27. Through the aforementioned structural configuration, when the capacitive switch device 600 continuously changes between the unpressed state S11 and the pressed state S12, the capacitive switch device 600 can generate a switch signal between the unpressed state S11 and the pressed state S12. In detail, when the capacitive switch device 600 is in the unpressed state S11, the several turns of the elastic body 630 are separated from the first conductive member 640 and the second conductive member 650, respectively, so the medium between the first conductive member 640 and the second conductive member 650 is mainly affected by the air, thereby generating a relatively small capacitance. However, when the capacitive switch device 600 is in the pressed state S12, the several turns of the elastic body 630 approach the first conductive member 640 and the second conductive member 650, so the medium between the first conductive member 640 and the second conductive member 650 is more affected by the several turns of the elastic body 630, thereby generating a relatively large capacitance. Since the capacitance value is positively correlated with the dielectric constant, the capacitive switch device 600 can generate a switching signal associated with the dielectric constant of the medium between the first conductive element 640 and the second conductive element 650 .

[0181] From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the capacitive switch device disclosed in the present disclosure, since the sliding member slides relative to the lower cover in the third direction through the elastic body, the user can repeatedly press the capacitive switch device as a keyboard key. In the capacitive switch device disclosed in the present disclosure, since the first conductive member is fixed on the circuit board and is stationary relative to the lower cover, and the second conductive member moves relative to the first conductive member as the sliding member slides, when the second conductive member moves relative to the first conductive member, a capacitance will be generated between the second conductive member and the first conductive member. In the capacitive switch device disclosed in the present disclosure, when the second conductive member moves relative to the first conductive member, the capacitance value between the second conductive member and the first conductive member will change with the overlapping area of ​​the second conductive member and the first conductive member or the distance between the second conductive member and the first conductive member, so that when the user presses the capacitive switch device, a switch signal associated with the overlapping area of ​​the second conductive member and the first conductive member or the distance between the second conductive member and the first conductive member can be generated. In the capacitive switch device disclosed in the present invention, when the first conductive member and the second conductive member are fixed on the circuit board, the user can generate a capacitance change by controlling the dielectric constant of the medium between the first conductive member and the second conductive member, so that when the user presses the capacitive switch device, a switch signal associated with the dielectric constant of the medium between the first conductive member and the second conductive member can be generated. In this way, compared with the traditional mechanical switch that can only generate an all-or-nothing switch signal of a pressed state and a non-pressed state, the capacitive switch device disclosed in the present invention can generate a switch signal between a pressed state and a non-pressed state, thereby increasing the flexibility and possibility of keyboard keys in the field of e-sports.

[0182] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
