Description

Technical Field

[0001] This utility model belongs to the technical field of tilt switches, and particularly relates to a patch omnidirectional tilt switch. Background Technology

[0002] A tilt-sensing switch is an electronic device that uses a conductive ball to sense changes in the tilt angle to change the switch's open or closed state, and then transmits the sensing result to the circuit device. It is commonly used to realize functions such as tilt-triggered power-off protection, tilt-triggered alarm, and direction and angle recognition. For example, it is used in smart gas / electric meters, heaters, home appliances / small appliances, medical devices, smart homes, smart digital products, smart toys, and various sensing systems for alarm or detection protection applications to trigger or wake up the device.

[0003] Existing tilt sensor switches have relatively simple and rigid structures. They are not only relatively large in size, but also have inaccurate tilt trigger angles for the ball bearings. Furthermore, the structural design of a single trigger circuit has poor reliability, which cannot meet the requirements of low-error and high-reliability application scenarios in many industries. Therefore, this utility model proposes a new solution to the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a surface mount omnidirectional tilt switch, which adopts a multi-channel parallel conduction circuit structure design to improve the stability of the surface mount omnidirectional tilt switch during use, enhance the trigger sensitivity and reliability of the surface mount omnidirectional tilt switch, and extend the service life of the surface mount omnidirectional tilt switch.

[0005] Based on this, the present invention provides a patch omnidirectional tilt switch, comprising: The first connecting plate is an electrode used to conduct the circuit; The second connecting plate is connected to one side of the first connecting plate. The second connecting plate is provided with a metallized tapered through hole for the conductive ball to be placed movably. The tapered through hole is the other electrode of the conductive circuit. The third connecting plate is connected to the other side of the second connecting plate relative to the first connecting plate. The third connecting plate is provided with a metallized conical blind hole. The conical blind hole and the first connecting plate are the same electrode for conducting the circuit. The conical through hole and the conical blind hole surround and form a cavity for restricting the movement of the conductive ball. The side of the second connecting plate that connects to the first connecting plate is defined as side A, and the side that connects to the third connecting plate is defined as side B. The conical through-hole penetrates both surface A and surface B. There are at least two conical through-holes and two conical blind holes, and their positions correspond one-to-one. The two conical through-holes or conical blind holes are spaced apart and connected. The conical blind holes are used to define the tilt trigger angle. Each of the movable cavities contains a conductive ball. When multiple conductive balls exceed the preset trigger angle, they roll and simultaneously contact the third connecting plate and the second connecting plate, or the first connecting plate and the second connecting plate, thereby forming a multi-path parallel conductive circuit.

[0006] As described above, in a surface-mount omnidirectional tilt switch, the tapered through-hole is designed with an inverted structure, and the diameter of the tapered through-hole on surface A is smaller than the diameter of the tapered through-hole on surface B.

[0007] As described above, in a surface mount omnidirectional tilt switch, the second connecting plate includes a first connecting wire group for connecting to an external circuit. The first connecting wire group is disposed on the B side and is connected to the same tapered through hole. The second connecting plate further includes a first guide channel for connecting adjacent tapered through holes, the first guide channel being disposed on surface B.

[0008] As described above, in a surface-mount omnidirectional tilt switch, the side of the first connecting plate that contacts surface A is defined as surface C, and the other side opposite surface C is defined as surface D. Surface C is provided with at least two first electrode pieces for connecting external circuits. The first electrode pieces are arranged in a one-to-one correspondence with the tapered through holes, and the two first electrode pieces are spaced apart and connected. The conductive ball simultaneously contacts the tapered through holes and the first electrode pieces to conduct the circuit.

[0009] As described above, in a surface-mount omnidirectional tilt switch, the first electrode plate is provided with an arc-shaped contact extending toward the second connecting plate. The arc-shaped contact is connected to the first electrode plate and is used for contact by the conductive ball.

[0010] As described above, in a surface mount omnidirectional tilt switch, the C-side is provided with a second connecting wire group for connecting an external circuit and a second conductive channel for conducting two adjacent first electrode plates. The second connecting wire group is connected to the same first electrode plate, and the first connecting wire group and the second connecting wire group are arranged opposite to each other on both sides of the surface mount omnidirectional tilt switch.

[0011] As described above, in a surface mount omnidirectional tilt switch, the D-side is further provided with a first pad for connecting an external circuit. The two first pads are respectively located on one side of the first connecting plate near the second connecting line group and on the other side away from the second connecting line group, and the second connecting line group is connected to the first pad near the second connecting line group.

[0012] In the surface mount omnidirectional tilt switch described above, the side of the third connecting plate that contacts the B surface is defined as the E surface, and the other side opposite the E surface is defined as the F surface. The tapered blind hole is opened on the E surface but does not penetrate the F surface. The conductive ball simultaneously contacts the tapered through hole and the tapered blind hole to conduct the circuit.

[0013] As described above, in a surface mount omnidirectional tilt switch, the E-side is provided with a third connecting wire group for connecting an external circuit and a third conductive channel for connecting two adjacent conical blind holes. The third connecting wire group is connected to the same conical blind hole, and the third connecting wire group and the first connecting wire group are arranged opposite to each other on both sides of the surface mount omnidirectional tilt switch.

[0014] As described above, in a surface mount omnidirectional tilt switch, the F-side is provided with a second pad for connecting an external circuit. The two second pads are respectively located on one side of the third connecting plate near the third connecting line group and on the other side away from the third connecting line group, and the third connecting line group is connected to the second pad near the third connecting line group.

[0015] The beneficial effects of this utility model are as follows: This solution employs a multi-path parallel conduction circuit design. Firstly, the first, second, and third connecting plates are stacked sequentially, forming multiple independent movable cavities using multiple metallized tapered through holes and tapered blind holes. A conductive ball is placed in each movable cavity, effectively reducing the overall thickness of the surface mount omnidirectional tilt switch and facilitating a reduction in its overall volume. Secondly, the tapered blind holes define the tilt trigger angle. When the preset trigger angle is exceeded, multiple conductive balls roll within each movable cavity and simultaneously contact the third and second connecting plates, or the first and second connecting plates, forming a multi-path parallel conduction circuit. This allows for signal output by simultaneously conducting any one or more conductive balls, ensuring normal operation even if a single path fails. This significantly improves the reliability and trigger sensitivity of the surface mount omnidirectional tilt switch, enhancing its stability during use, increasing its trigger sensitivity and reliability, and extending its service life.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: like Figures 1 to 10 As shown, Embodiment 1 of this utility model provides a patch omnidirectional tilt switch, comprising: A first connecting plate 1, a second connecting plate 2, and a third connecting plate 3 are defined. The first connecting plate 1 serves as one electrode for conducting the circuit. The first connecting plate 1 is connected to one side of the second connecting plate 2, which has a metallized tapered through-hole 21 for the movable placement of a conductive ball 4. The tapered through-hole 21 serves as the other electrode for conducting the circuit. The third connecting plate 3 is connected to the other side of the second connecting plate 2, opposite to the first connecting plate 1. The third connecting plate 3 has a metallized tapered blind hole 31, which, along with the first connecting plate 1, serves as the same electrode for conducting the circuit. The tapered through-hole 21 and the tapered blind hole 31 together form a cavity for restricting the movement of the conductive ball 4. The side of the second connecting plate 2 connected to the first connecting plate 1 is called surface A, and the side connected to the third connecting plate 3 is called surface B. The tapered through hole 21 penetrates both surface A and surface B. At least two tapered through holes 21 and two tapered blind holes 31 are provided, and their positions correspond one-to-one. The two tapered through holes 21 or the tapered blind holes 31 are spaced apart and connected. The tapered blind holes are used to define the tilt trigger angle. Each movable cavity contains one conductive ball 4. Multiple conductive balls 4, after exceeding a preset trigger angle, roll and simultaneously contact the third connecting plate 3 and the second connecting plate 2, or the first connecting plate 1 and the second connecting plate 2, thereby forming a multi-path parallel conductive circuit.

[0021] In Embodiment 1 of this utility model, at least two spaced and interconnected tapered through holes 21 are provided on the second connecting plate 2, and at least two spaced and interconnected tapered blind holes 31 are provided on the third connecting plate 3. Multiple tapered through holes 21 and tapered blind holes 31 surround and form a movable cavity. A conductive ball 4 is placed in each movable cavity. The second connecting plate 2 is configured as one electrode of the conductive circuit, and the first connecting plate 1 and the second connecting plate 2 are the other electrode of the conductive circuit. This allows multiple conductive balls 4 to roll freely within each movable cavity while simultaneously contacting the third connecting plate 3 and the second connecting plate 2, or the first connecting plate 1 and the second connecting plate 2 to form a parallel conductive circuit. As long as any one of these circuits is connected, the surface mount omnidirectional tilt switch can be activated, effectively solving the technical problem of poor stability of a single circuit. This improves the stability of the surface mount omnidirectional tilt switch during use and reduces its thickness. Furthermore, Embodiment 1 of this utility model improves the rolling flexibility of the conductive ball 4 and reduces production costs by providing a conductive ball 4 in each movable cavity.

[0022] The conductive ball 4 achieves circuit conduction when it simultaneously contacts the second connecting plate 2 and the first connecting plate 1 or the second connecting plate 2 and the third connecting plate 3. It can simultaneously form a parallel conducting circuit with either connecting plate on both sides, thereby achieving 360° omnidirectional high-sensitivity triggering. This ensures that the surface mount omnidirectional tilt switch can conduct stably and reliably at various angles, effectively enhancing the triggering sensitivity and reliability of the surface mount omnidirectional tilt switch.

[0023] In Embodiment 1 of this utility model, the number of tapered through holes 21, tapered blind holes 31, and conductive balls 4 are in one-to-one correspondence, ensuring that each of the movable cavities contains one conductive ball 4. This allows the conductive ball 4 to simultaneously contact either the tapered through hole 21 or either the first connecting plate 1 or the tapered blind hole 31 to form a conductive circuit, avoiding single-path failure and extending the service life and improving the reliability of the surface mount omnidirectional tilt switch. In Embodiment 1 of this utility model, it is preferable to provide two tapered through holes 21, tapered blind holes 31, and conductive balls 4 to reduce the overall volume of the surface mount omnidirectional tilt switch and ensure its applicability.

[0024] In some other embodiments, in order to reduce the maintenance and replacement of the surface mount omnidirectional tilt switch, the number of tapered through holes 21, tapered blind holes 31 and conductive balls 4 can be increased according to actual needs to improve the flexibility of the surface mount omnidirectional tilt switch during use.

[0025] Specifically, the tapered through hole 21 has an inverted structure design, and the diameter of the tapered through hole 21 on surface A is smaller than the diameter of the tapered through hole 21 on surface B.

[0026] In Embodiment 1 of this utility model, the constricted end of the inverted conical through-hole 21 is located on surface A, and the difference in its aperture forms a wedge-shaped guide surface, which can achieve a more precise tilt threshold setting within a limited height, thereby improving the triggering flexibility of the conductive ball 4. At the same time, through the design of the inclined surface, the conductive ball 4 can roll along the inclined surface when the surface-mount omnidirectional tilt switch is tilted, which can effectively prevent the surface-mount omnidirectional tilt switch from failing to conduct due to the conductive ball 4 remaining stationary in the conical through-hole 21 when the surface-mount omnidirectional tilt switch is tilted to 90°, thereby improving the stability of the surface-mount omnidirectional tilt switch during operation.

[0027] Preferably, the aperture of side B is larger than the maximum diameter of the conductive ball 4, and the aperture of side A is smaller than the maximum diameter of the conductive ball 4. Furthermore, when the aperture of side A is at its minimum, it ensures that the exposed portion of the conductive ball 4 contacts the first connecting plate 1 to conduct the circuit. Furthermore, the second connecting plate 2 includes a first connecting wire group 22 for connecting external circuits. The first connecting wire group 22 is disposed on the B side and is connected to the same tapered through hole 21. The second connecting plate 2 further includes a first guide channel 23 for connecting adjacent tapered through holes 21, the first guide channel 23 being disposed on surface B.

[0028] In Embodiment 1 of this utility model, the first connecting line group 22 includes a first connecting line 221 and a second connecting line 222. The first connecting line 221 and the second connecting line 222 are connected to each other on both sides of the same tapered through hole 21 to connect the tapered through hole 21 with the external circuit, forming a parallel dual-path, thereby enhancing the stability and reliability of the surface mount omnidirectional tilt switch during use.

[0029] In Embodiment 1 of this utility model, the two tapered through holes 21 are connected by the first guide channel 23 to ensure that each tapered through hole 21 is connected to the external circuit, so that the surface mount omnidirectional tilt switch forms a multi-parallel conducting circuit, thereby enhancing the reliability of the surface mount omnidirectional tilt switch.

[0030] Furthermore, the side of the first connecting plate 1 that contacts surface A is defined as surface C, and the other side opposite surface C is defined as surface D. Surface C is provided with at least two first electrode pieces 11 for connecting external circuits. The first electrode pieces 11 are arranged in a one-to-one correspondence with the tapered through holes 21, and the two first electrode pieces 11 are spaced apart and connected. The conductive ball 4 simultaneously contacts the tapered through holes 21 and the first electrode pieces 11 to conduct the circuit.

[0031] In Embodiment 1 of this utility model, the first electrode sheet 11 and the tapered through hole 21 are the same pole of the patch omnidirectional tilt switch. Preferably, there are two first electrode sheets 11, and the two first electrode sheets 11 are spaced apart and connected to each other to ensure that they correspond one-to-one with the two tapered through holes 21 for the conductive ball 4 to contact and form a parallel conductive circuit, thereby reducing the overall volume of the patch omnidirectional tilt switch and ensuring the applicability and reliability of the patch omnidirectional tilt switch.

[0032] In Embodiment 1 of this utility model, the first electrode sheet 11 is disposed on the C-surface to ensure that the conductive ball 4 can simultaneously contact the tapered through hole 21 and the first electrode sheet 11 after exceeding the preset trigger angle during the rolling process, thereby conducting the circuit and enhancing the omnidirectional conductivity of the patch omnidirectional tilt switch.

[0033] Furthermore, the first electrode plate 11 is provided with an arc-shaped contact 111 extending toward the second connecting plate 2. The arc-shaped contact 111 is connected to the first electrode plate 11 and is used for the conductive ball 4 to make contact.

[0034] In Embodiment 1 of this utility model, when the third connecting plate 3 is placed horizontally and the conductive ball 4 abuts against it, it is in the initial state of a normally open circuit. Since the diameter of the conical through hole 21 on surface A is smaller than the maximum diameter of the conductive ball 4, during the rolling process of the conductive ball 4, by setting the arc-shaped contact 111 with a diameter smaller than the opening on surface A, when the first connecting plate 1 is connected to the second connecting plate 2, the arc-shaped contact 111 can be inserted into the conical through hole 21. By abutting against the arc surface of the arc-shaped contact 111, the conductive ball 4 ensures that it always maintains simultaneous contact with the inner wall of the conical through hole 21 and the first electrode plate 11, so that when the conductive ball 4 tilts and moves to simultaneously contact the second connecting plate 2 and the first connecting plate 1, or the second connecting plate 2 and the third connecting plate 3, it is always in a conductive state, thereby improving the trigger sensitivity of the patch omnidirectional tilt switch.

[0035] Furthermore, the C-side is provided with a second connecting line group 12 for connecting external circuits and a second conductive channel 13 for conducting two adjacent first electrode pieces 11. The second connecting line group 12 is connected to the same first electrode piece 11, and the first connecting line group 22 and the second connecting line group 12 are arranged opposite to each other on both sides of the surface mount omnidirectional tilt switch.

[0036] In Embodiment 1 of this utility model, the second connecting line group 12 includes a third connecting line 121 and a fourth connecting line 122. The third connecting line 121 and the fourth connecting line 122 are connected to the same first electrode plate 11 to connect the first electrode plate 11 with the external circuit, forming a parallel dual-path, which enhances the stability and reliability of the surface mount omnidirectional tilt switch during use. At the same time, the first connecting line group 22 and the second connecting line group 12 are arranged opposite to each other on both sides of the surface mount omnidirectional tilt switch, which can effectively prevent short circuits from occurring during the conduction process of the surface mount omnidirectional tilt switch and improve the safety of the surface mount omnidirectional tilt switch during use.

[0037] Furthermore, the D-side is also provided with a first pad 14 for connecting external circuits. The two first pads 14 are respectively provided on one side of the first connecting plate 1 near the second connecting line group 12 and on the other side away from the second connecting line group 12, and the second connecting line group 12 is connected to the first pad 14 near the second connecting line group 12.

[0038] In Embodiment 1 of this utility model, the third connecting line 121 and the fourth connecting line 122 are respectively connected to the first pad 14 near the second connecting line group 12 to reduce the conduction distance between the third connecting line 121, the fourth connecting line 122 and the first pad 14, thereby achieving the shortest conduction and improving the space utilization of the first connecting board 1. At the same time, the spacing of the two first pads 14 avoids short circuits when conducting external circuits, effectively enhancing the safety of the surface mount omnidirectional tilt switch during use.

[0039] Furthermore, the side of the third connecting plate 3 that contacts the B surface is defined as the E surface, and the other side opposite the E surface is defined as the F surface. The tapered blind hole 31 is opened on the E surface but does not penetrate the F surface. The conductive ball 4 simultaneously contacts the tapered through hole 21 and the tapered blind hole 31 to conduct the circuit.

[0040] In Embodiment 1 of this utility model, the conical blind hole 31 has an opening on surface E but does not penetrate surface F, which can effectively improve the sealing performance of the surface mount omnidirectional tilt switch. The opening of the conical blind hole 31 on surface E is aligned with the conical through hole 21, and the small end of the conical blind hole 31 stops inside the third connecting plate 3, so that when the conductive ball 4 is inserted into the conical blind hole, it returns to its initial state, making the surface mount omnidirectional tilt switch non-conductive and enhancing the stability of the surface mount omnidirectional tilt switch during use. At the same time, by setting the angle of the conical blind hole 31, the trigger angle of the surface mount omnidirectional tilt switch can be set, ensuring that after the conductive ball 4 rolls to a position exceeding the preset trigger angle, the conductive ball 4 can simultaneously contact the conical through hole 21 and the conical blind hole 31 to connect the circuit, effectively enhancing the trigger sensitivity of the surface mount omnidirectional tilt switch.

[0041] Furthermore, the E-side is provided with a third connecting line group 32 for connecting external circuits, and a third guiding channel 33 for conducting two adjacent conical blind holes 31. The third connecting line group 32 is connected to the same conical blind hole 31, and the third connecting line group 32 and the first connecting line group 22 are arranged opposite to each other on both sides of the surface mount omnidirectional tilt switch.

[0042] In Embodiment 1 of this utility model, the two tapered blind holes 31 are connected through the third guide channel 33 to ensure that they correspond one-to-one with the two tapered through holes 21 to form a parallel conducting circuit, thereby reducing the overall volume of the surface mount omnidirectional tilt switch and ensuring the applicability and reliability of the surface mount omnidirectional tilt switch.

[0043] In Embodiment 1 of this utility model, the third connecting wire group 32 includes a fifth connecting wire 321 and a sixth connecting wire 322. The fifth connecting wire 321 and the sixth connecting wire 322 are connected to the same conical blind hole 31 to connect the conical blind hole 31 to the external circuit, forming a parallel dual-path, which enhances the stability and reliability of the surface mount omnidirectional tilt switch during use. At the same time, the third connecting wire group 32 and the first connecting wire group 22 are arranged opposite to each other on both sides of the surface mount omnidirectional tilt switch, ensuring that the third connecting wire group 32 and the second connecting wire group 12 are located on the same side of the surface mount omnidirectional tilt switch, while the first connecting wire group 22 is located on the opposite side of the third connecting wire group 32 and the second connecting wire group 12. This can effectively prevent short circuits from occurring after the surface mount omnidirectional tilt switch is turned on, and improve the safety of the surface mount omnidirectional tilt switch in use.

[0044] In Embodiment 1 of this utility model, the diameter of the conical blind hole 31 is smaller than the diameter of the hole on surface B. By setting the conical blind hole 31, when the patch omnidirectional tilt switch is in the initial state, the conductive ball 4 can be inserted into the conical blind hole 31, thereby ensuring that the initial state is a circuit disconnected state. After the conductive ball 4 starts to roll, it achieves conduction by simultaneously contacting the conical through hole 21 and the conical blind hole 31, thereby enhancing the reliability of the patch omnidirectional tilt switch during use.

[0045] In Embodiment 1 of this utility model, the angle between the hypotenuse of the conical blind hole 31 and the vertical line perpendicular to plane E is defined as α, and the angle between the hypotenuse of the conical through hole 21 and the vertical line perpendicular to plane A is defined as β. Therefore, the forward triggering angle of the surface mount omnidirectional tilt switch is from α to 90°+β, and the reverse triggering angle is from 90°+β to 180°. Furthermore, by designing the hypotenuse of the conical through hole 21 as β, Embodiment 1 effectively prevents the conductive ball 4 from remaining stationary within the conical through hole 21 when the surface mount omnidirectional tilt switch is tilted to 90°, thus avoiding the failure of the surface mount omnidirectional tilt switch to conduct. This allows the conductive ball 4 to roll and simultaneously contact both the conical through hole 21 and the arc-shaped contact 111, thereby ensuring smooth conduction of the surface mount omnidirectional tilt switch when tilted to 90°, and improving the stability of the surface mount omnidirectional tilt switch during operation.

[0046] Furthermore, the F-side is provided with a second pad 34 for connecting external circuits. The two second pads 34 are respectively located on the side of the third connecting plate 3 near the third connecting line group 32 and on the other side away from the third connecting line group 32, and the third connecting line group 32 is connected to the second pad 34 near the third connecting line group 32.

[0047] In Embodiment 1 of this utility model, the fifth connecting line 321 and the sixth connecting line 322 are respectively connected to the second pad 34 near the third connecting line group 32 to reduce the conduction distance between the fifth connecting line 321, the sixth connecting line 322 and the second pad 34, thereby achieving the shortest conduction and improving the space utilization of the third connecting board 3. At the same time, the spacing of the two second pads 34 avoids short circuits when conducting external circuits, effectively enhancing the reliability of the surface mount omnidirectional tilt switch during use.

[0048] In Embodiment 1 of this utility model, the outer side of the first connecting plate 1 is provided with a plurality of first external conductive channels 15. Two of the first external conductive channels 15 are located near the second connecting line group 12, one end of which is connected to the first pad 14, and the other end of which is connected to the third connecting line 121 and the fourth connecting line 122 respectively to conduct external circuits. The outer side of the third connecting plate 3 is provided with a plurality of third external conductive channels 35, and the outer side of the second connecting plate 2 is provided with a plurality of second external conductive channels 24. Two of the third external conductive channels 35 are located near the third connecting line group 32, one end of which is connected to the second pad 34, and the other end of which is connected to the fifth connecting line 321 and the sixth connecting line 322 respectively to conduct external circuits. The two external conductive channels 15 located away from the first connecting line group 22 are also provided with a plurality of third external conductive channels 35. The second external conductive channel 24 is connected to the two first external conductive channels 15 near the side of the second connecting line group 12 and the two third external conductive channels 35 near the side of the third connecting line group 32, so as to conduct the first pad 14 and the second pad 34 disposed on the same side; one end of the two second external conductive channels 24 near the side of the first connecting line group 22 is connected to the two first external conductive channels 15 away from the side of the second connecting line group 12, and the other end of the two second external conductive channels 24 is connected to the two third external conductive channels 35 away from the side of the third connecting line group 32, so as to conduct the first pad 14 and the second pad 34 on the other side, and the first connecting line 221 and the second connecting line 222 are respectively connected to the two second external conductive channels 24 to conduct external circuits, so as to enhance the conduction stability of the surface mount omnidirectional tilt switch.

[0049] In Embodiment 1 of this utility model, the tapered through hole 21, tapered blind hole 31, multiple first external conductive channels 15, second external conductive channels 24, and third external conductive channels 35 are connected by metallization. The metal layer is thickened by chemical copper plating combined with electroplating to enhance conductivity.

[0050] In Embodiment 1 of this utility model, the surface mount omnidirectional tilt switch is directly soldered onto the PCB board 5 via the second pad 34; or, by providing a socket in the second pad 34, a pin is connected to the socket and inserted into the PCB board 5 via the pin, thereby improving the installation flexibility of the surface mount omnidirectional tilt switch.

[0051] Example 2: The difference between this embodiment 2 and embodiment 1 is that by omitting the second connecting wire group 12 in the structural design of the first connecting plate 1, a non-conductive surface mount tilt switch of the first connecting plate 1 can be made, that is, a one-way surface mount tilt switch that is non-conductive on the reverse side, so as to enhance the applicability of the tilt switch in different application scenarios.

[0052] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.
