Description

Technical Field

[0001] The present invention relates to the technical field of electrical switches, and in particular to a magnetically controlled electrical switch. Background Art

[0002] Currently, electrical switches on the market fall into two main categories: mechanical switches primarily based on a rocker mechanism, and electronic switches primarily based on touch or sensing. Existing mechanical rocker switches are typically wall-mounted, used to connect and disconnect circuits, thereby controlling lights or other electrical appliances.

[0003] Taking a mechanical switch mounted on a wall as an example, its structure generally consists of a panel, housing, spring, rocker contact (L pole), and make contact (L1 pole). Pressing the panel on the housing downwards causes the panel to flip, which in turn moves the spring pressing against the rocker contact. The upward force of the spring presses the rocker contact and the make contact together, completing the circuit-closing action. Pressing the panel on the housing upwards causes the panel to flip, which in turn moves the spring pressing against the rocker contact. The downward force of the spring separates the rocker contact and the make contact, completing the circuit-closing action.

[0004] However, when existing wall switches are in use, the panel, spring, and rocker contact are rigidly connected by spring force to produce linkage, so a socket for the linkage is left in the housing, causing the electrical connection chamber in the housing to be connected to the external living environment. The relationship between electricity and the living environment is open, which is very likely to cause leakage and harm to life in humid environments such as bathrooms or showers. Even in non-humid environments, external dust will enter the electrical connection chamber, and the dust will accumulate over time. When turning the light on or off, the dust in the electrical connection chamber will be ignited by sparks, causing a fire (Note: The material of the spring in the electrical connection chamber of existing wall switches will produce metal fatigue after a certain period of time, and the elasticity will gradually weaken, resulting in loose contact and sparks). Every year, there are many leakage and fire accidents caused by wall switches.

[0005] In addition, the principle of the linkage action of the spring and rocker contacts in existing wall switches is similar to the principle of the spring hitting the pin in a pistol. When the switch is in use, it will emit a crisp impact sound. Because the electrical connection chamber is connected to the external environment, the crisp impact sound will be transmitted to the living environment without reservation, especially at night. This sound is very annoying for people with poor sleep quality.

[0006] Furthermore, existing wall switches feature contact-connected panels and all operating components. For electrical and thermal conductivity safety, the panel becomes the final flame-retardant barrier, limiting the panel's material choices to a single flame-retardant PC plastic. While wall switches have both decorative and practical properties, a single panel material limits their decorative appeal. This also hinders the artistic, cultural, and personalized nature of the wall switch panel.

[0007] Therefore, it is necessary to develop an electrical switch to overcome the shortcomings of existing electrical mechanical switches. Summary of the Invention

[0008] The object of the present invention is to provide a magnetically controlled electrical switch, which solves the problems of low safety, short life and noise of existing electrical mechanical switches.

[0009] To achieve the above object, the technical solution adopted by the present invention is:

[0010] The present invention provides a magnetic control electrical switch, comprising: a panel, a housing and a switch assembly;

[0014] The bottom of the deep groove is located directly above the connecting block; the first magnet moves bidirectionally along the deep groove under the force of the panel and the force between the first magnet and the second magnet;

[0015] When the first magnet deviates from the position directly above the connecting block, the first magnet and the second magnet generate an attractive force, driving the contact of the connecting block to be connected with the first static contact; when the first magnet moves to the bottom of the deep groove, the first magnet and the second magnet generate a repulsive force, driving the contact of the connecting block to be disconnected from the first static contact.

[0016] Furthermore, the electrical connection chamber further comprises: a second terminal; the second terminal is provided with a second static contact; the upper end surface of the contact of the connection block is a first moving contact, and the lower end surface is a second moving contact;

[0018] When the first magnet moves to the top of the connecting block, the first magnet and the second magnet generate a repulsive force, driving the second movable contact of the connecting block and the second static contact to be connected, and the first movable contact is in a disconnected state.

[0019] Furthermore, the panel and the housing are movably connected via a clamping assembly; the clamping assembly comprises: a clamping slot and a matching clamping column;

[0020] The panel is mounted with a card slot, and the housing is mounted with the card column; or the panel is mounted with a card column, and the housing is mounted with the card slot.

[0021] Furthermore, on the mounting surfaces of the panel and the shell opposite to each other, a third magnet is mounted on the panel, and a fourth magnet is mounted on the shell; the third magnet and the fourth magnet are attracted to each other.

[0022] Furthermore, when the first magnet deviates from the position directly above the connecting block, the first magnet and the second magnet generate an attractive force; the attractive force plus the force of the panel is greater than the combined attractive force of the third magnet and the fourth magnet, and the panel and the housing are in different planes;

[0023] When the first magnet moves to just above the connecting block, the first magnet and the second magnet generate a repulsive force; the repulsive force is smaller than the attractive force of the third magnet and the fourth magnet, and the panel and the shell are in the same plane.

[0024] Furthermore, the deep groove and the first magnet have the same shape, both of which are columnar.

[0025] Furthermore, the second magnet is embedded in the connecting block; the surface of the second magnet is flush with the embedding surface.

[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0046] Reference Figure 1a-1b As shown, the present invention provides a magnetic control electrical switch, comprising: a panel 1, a housing 2 and a switch assembly 3;

[0047] The panel 1 is covered on one side of the housing 2 and is movably connected to the housing 2; the switch assembly 3 serves as an electrical connection chamber and is installed on the other side of the housing 2;

[0048] A deep groove 4 with one end open is provided on the side of the housing 2 opposite to the panel 1. A first magnet 5 is provided in the deep groove 4. The panel 1 abuts against the first magnet 5.

[0049] The electrical connection chamber includes: a conductive end 31, a connecting block 32 and a first terminal 33; a second magnet 34 is provided on the connecting block 32; one end of the connecting block 32 is movably connected to the conductive end 31, and the other end is a contact; in a specific implementation, for example, the conductive end 31 is provided with a connecting column, and one end of the connecting block 32 is provided with a through hole; the connecting column and the through hole are adapted to be plugged in; one end of the connecting block 32 is movably connected to the conductive end 31, and the other end is connected and disconnected with the static contact.

[0050] A first static contact 331 is provided on the top of the first terminal 33; Figure 1a and 1b In the embodiment, the electrical connection chamber is blocked by a cover plate 6 , and the cover plate 6 is fixedly mounted on the electrical connection chamber using screws 7 .

[0051] The bottom of the deep groove 4 is located directly above the connecting block 32; the first magnet 5 moves along the deep groove 4 toward the bottom of the groove under the force of the panel 1; or after the force of the panel 1 is released, the first magnet 5 moves toward the opening of the deep groove under the action of the attraction force between the second magnet and the repulsive force.

[0052] The operating principle is as follows: deep groove 4 and first magnet 5 have the same shape. The first magnet 5 is inserted into deep groove 4, and the passage through deep groove 4 forms a guide for the movement of the first magnet 5. When the first magnet 5 deviates from the position directly above the connecting block 32, the first magnet 5 and the second magnet 34 generate an attractive force, which causes the contact of the connecting block 32 to connect with the first static contact 331 of the first terminal 33. When the first magnet 5 moves to the bottom of deep groove 4, the first magnet 5 and the second magnet 34 generate a repulsive force, which causes the contact of the connecting block 32 to disconnect from the first static contact of the first terminal 33.

[0053] When the magnet is manufactured, no matter what shape it is, a magnetization direction will be selected according to the production needs, such as Figure 2a 、 2b As shown, the magnetization direction is marked with S and the magnetization direction is marked with N. When two magnets meet, the magnetization directions are consistent, and the S section of one magnet and the N section of the other magnet generate an attractive force, as shown in the figure. Figure 2a As shown; other cross sections will produce repulsive forces when they meet, such as Figure 2b In this embodiment, Figure 2a 、 2b The magnet A in the figure is equivalent to the first magnet, and the magnet B is equivalent to the second magnet.

[0054] In a specific implementation, for example, the first magnet is a cylindrical N35-N45 magnet; the second magnet is a block-shaped N45-N52 magnet, which can be embedded in the connecting block 32. Ensure that the surface of the second magnet 34 is flush with the embedding surface. The first and second magnets are magnetized in the same direction, and the positional shift between them controls the magnets' attraction and repulsion, which in turn activate and deactivate the moving and stationary contacts within the wall switch's electrical connection chamber.

[0055] In one embodiment, the magnetically controlled electrical switch can also be made into a one-on, two-control, one-on, three-control, one-on, four-control, etc.

[0056] Take one open and two control as an example, Figure 3a 、 3b As shown, the electrical connection chamber further includes: a second terminal 35 having a second static contact 351; the upper end surface of the contact of the connection block 32 is a first movable contact 321, and the lower end surface is a second movable contact 322;

[0057] like Figure 3a As shown, under the action of the panel, when the first magnet 5 deviates from the top of the connecting block 32, that is, moves along the deep groove 4 toward the opening, the first magnet 5 and the second magnet 34 generate an attractive force; the first moving contact 321 of the connecting block 34 and the first static contact 331 are brought into conduction; the first moving contact 322 is in a disconnected state.

[0058] like Figure 3b As shown, under the action of the panel, when the first magnet 5 moves to the top of the connecting block 32, the first magnet 5 and the second magnet 34 generate a repulsive force, driving the second moving contact 322 of the connecting block 32 and the second static contact 351 to be conductive, and the first moving contact 321 is in a disconnected state.

[0059] In one embodiment, on the mounting surfaces opposite to each other, the panel 1 and the shell 2, a third magnet 11 is mounted on the panel 1 and a fourth magnet 21 is mounted on the shell; the positions of the two correspond to each other, and when the panel 1 is covered on the shell 2, the third magnet 11 and the fourth magnet 21 are in an attracted state, and at this time, the panel 1 and the shell 2 are in the same plane.

[0060] When the first magnet 5 moves to just above the connecting block 32 , the first magnet 5 and the second magnet 34 generate a repulsive force; the repulsive force is smaller than the attractive force of the third magnet 11 and the fourth magnet 21 . At this time, the panel 1 and the shell 2 are in the same plane.

[0061] Under the action of the panel 1, the repulsive force between the first magnet 5 and the second magnet 34 is released, and the first magnet 5 deviates from the top of the connecting block 32. At this time, the first magnet 5 and the second magnet 34 generate an attractive force; therefore, the attractive force plus the action of the panel 1 is greater than the attractive force of the third magnet 11 and the fourth magnet 21. At this time, the panel 1 and the shell 3 are in different planes.

[0062] In one embodiment, Figure 1a 、 1b As shown, the panel 1 and the housing 2 are movably connected via a snap-fit assembly; the snap-fit assembly includes: a snap-fit slot 12 and a matching snap-fit column 22;

[0063] like Figure 1a 、 1b As shown, the panel 1 is mounted with the slot 12, and the housing 2 is mounted with the post 22. Alternatively, the panel can be mounted with the post, and the housing can be mounted with the slot. This type of snap-on assembly has a simple structure, is easy to install, and has good performance. It has a good connection and fastening effect, is not easy to loosen or shake, and is easy to remove and replace panels of different materials.

[0064] The magnetic control electrical switch of the present invention has a panel that is a magnetic contactless control switch, which can release the selection of materials and processes for the wall switch panel, and does not need to use the switch panel as the final flame retardant barrier. In this way, the panel material and process can be expanded to include artistic bone porcelain, handmade purple clay, high-temperature fired teapots, precious solid wood, Hetian jade, cloisonné enamel, silk embroidery, natural textured stone, etc., and can also integrate Chinese calligraphy and totem culture as well as auspicious pattern cultures of various ethnic groups into the switch panel through changes in materials and processes, thereby improving the decorative and artistic attributes of the wall switch, realizing personalized customization of the wall switch, and achieving zero-gap matching with various types of decorative styles.

[0065] To enhance visibility at night, a fluorescent area 13 containing fluorescent powder can be provided on the panel surface. This light-storage luminous powder stores light energy when exposed to natural light, fluorescent light, ultraviolet light, and other sources. After the light stops, it slowly releases the energy as fluorescence. This allows the device to be visible at night or in the dark, lasting from several hours to over ten. This light can indicate the position of the switch, making it easier to identify and operate in dark environments.

[0066] In addition, a nighttime indicator light 13, a tritium lamp, is located on the switch panel. (Note: A tritium lamp consists of a sealed glass tube filled with a certain density of tritium gas. The inner wall of the glass tube is coated with phosphor. When the tritium gas reaches a certain density, it will continuously undergo fission, releasing electrons during fission. When the phosphor comes into contact with the electrons, it will emit light.) This tritium lamp requires no power and can emit light for 25 years. A switch panel equipped with a tritium lamp is easy to identify and operate in a dark environment.

[0067] The magnetically controlled electrical switch of the present invention can be used as a double-control switch, such as Figure 4 As shown in the figure, L is the live wire input port; L1 is the live wire output port; and L2 is the double-control output port. Two double-control switches are usually used to control a lamp or other electrical appliance. The L port of the lighting switch is connected to the live wire input port, while L1 and L2 are connected to the lighting wires.

[0068] If one switch controls one lamp, just select one connector between L1 and L2. If the switch is used for double control (two switches in two places control one lamp), L1 and L2 are connected to L1 and L2 of another switch, and L of the other switch is connected to the lighting lamp.

[0069] Compared to traditional mechanical switches, the magnetically controlled electrical switch provided by the present invention boasts a simpler structure, lacks elastic components, and utilizes magnetism to close and open circuits. It offers high stability and a long service life. Its electrical connection chamber is completely sealed, isolating it from the external living environment. This prevents injuries from electric shock caused by humidity and fires caused by dust accumulation. Furthermore, unlike traditional spring and rocker contacts, this design avoids the disturbing clattering noise produced by existing wall switches.

[0070] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
