Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a multi-control switch. Background Technology

[0002] Multi-control switches are mainly used in homes, hotels, shopping malls, and other places to control multiple lighting devices, electrical equipment, monitoring equipment, and other electrical devices. Generally, two double-control switches and multiple multi-control switches are used together to achieve the opening and closing control of the same electrical device from multiple locations. A multi-control switch includes a pushplate, switch knob, moving contact bridge, stationary contact, and conductive components. Existing multi-control switches have complex conductive component designs, a large number of terminals, and cumbersome wiring, requiring jumper wires and making wiring inconvenient. Furthermore, the wiring process of traditional multi-control switches is relatively complex, requiring a high level of professional skill from installers, making it difficult for users to operate and maintain themselves. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a multi-control switch that replaces the traditional jumper wire by extending the contact piece through a static contact bridge, so as to realize the function of switching between two sets of circuits without additional wiring and with reliable operation.

[0004] The technical solution of this utility model is as follows: A multi-control switch includes a base, a push plate, a switch button that can be pressed by the push plate, and a conductive switching component. The switch button has a first lever and a second lever, and the switch button corresponds to a set of conductive switching components. The conductive switching component includes a first inlet terminal, a first outlet terminal, a second inlet terminal, and a second outlet terminal, as well as a first conductive support piece and a second conductive support piece respectively connected to the two inlet terminals, a first stationary contact bridge and a second stationary contact bridge respectively connected to the two outlet terminals, and a first movable contact bridge and a second movable contact bridge respectively linked to the two levers of the switch button. The first stationary contact bridge and the second stationary contact bridge extend towards each other to form a first contact piece and a second contact piece. The first movable contact bridge is supported by the first conductive support piece and extends between the second contact piece and the first stationary contact bridge. The upper and lower end faces of the first movable contact bridge are respectively provided with a first movable contact and a second movable contact. The second contact piece and the first stationary contact bridge are respectively provided with a first stationary contact and a second stationary contact that are adapted to the corresponding movable contact. The second movable contact bridge is supported by the second conductive support piece and extends between the first contact piece and the second stationary contact bridge. The upper and lower end faces of the second movable contact bridge are respectively provided with a third movable contact and a fourth movable contact. The first contact piece and the second stationary contact bridge are respectively provided with a third stationary contact and a fourth stationary contact adapted to the corresponding movable contact. The switch button drives the first and second moving contact bridges to swing up and down synchronously, so that the moving contacts of the two moving contact bridges alternately contact the corresponding stationary contacts, thereby realizing the switching on and off of the two sets of circuits.

[0005] The above technical solution has the following beneficial effects: 1. Solves the pain points of traditional jumper wires and simplifies the wiring process. By extending the first and second stationary contact bridges to each other to form the first and second contact pieces, a cross conduction path between the two circuits is directly constructed. There is no need to set up additional jumpers for cross wiring, avoiding the cumbersome wiring and error-prone problems caused by traditional jumper wire connections. At the same time, it reduces the use of additional wiring components and simplifies switch assembly and subsequent maintenance operations. 2. The moving contact bridge is supported by a conductive support plate to ensure reliable conductive contact during the swing. The switch button drives the two levers to swing the first and second moving contact bridges up and down synchronously, so that the first / second moving contact of the first moving contact bridge alternately contacts the corresponding static contact of the second contact plate and the first static contact bridge, and the third / fourth moving contact of the second moving contact bridge alternately contacts the corresponding static contact of the first contact plate and the second static contact bridge, so as to realize the stable switching of the two sets of circuits.

[0006] A further feature of this invention is that: a mounting bracket is mounted on the base, and the mounting bracket has multiple downwardly extending pressure feet; each inlet terminal and outlet terminal is provided with a positioning post at its upper end, and each conductive support plate and stationary contact bridge is provided with a positioning hole, the positioning hole is adapted to the positioning post for insertion and positioning, and each conductive support plate and stationary contact bridge is pressed against the upper surface of the corresponding inlet terminal and outlet terminal by the corresponding pressure foot.

[0007] With the above-mentioned further configuration, the pressure feet of the mounting bracket press down against the conductive support plate and the stationary contact bridge, and with the insertion and positioning of the positioning post and positioning hole, the precise assembly and fixation of each conductive component is achieved, preventing the component from shifting when the switch is activated, ensuring the stability of the contact point, and avoiding poor contact due to loose components; at the same time, the standardized positioning and assembly structure simplifies the production and installation process and further reduces the difficulty of maintenance.

[0008] A further feature of this invention is that each end of the switch button is equipped with a pry bar. Both the switch button and the pry bar are rotatably mounted on the mounting bracket. One end of the pry bar is provided with a pressure head that is pressed by the button plate, and the other end is provided with a pair of drive rods that respectively abut against the two levers of the switch button. When either end of the button plate is pressed, the pry bar at the corresponding end can be driven to rotate, thereby pushing the switch button to swing to control the switch on and off.

[0009] By further configuring the above-mentioned design, a segmented rotational transmission structure of "button → pry bar → switch button" is constructed by configuring pry bars at both ends of the switch button. Compared with the design where the button directly drives the switch button, this design significantly shortens the transmission path, makes the internal structure of the switch more compact to meet the needs of miniaturization, and can also use the leverage characteristics of the pry bar to convert the linear pressing action of the button into a small-amplitude swing of the switch button, reducing the operating force and the risk of interference between the components. At the same time, the symmetrically configured pry bars at both ends can ensure that pressing either end of the button can stably drive the switch button, ensuring the reliability of bidirectional operation.

[0010] A further feature of this invention is that the base has an internal accommodating space, the inner wall of the base is provided with a vertical guide rod and a protrusion, the outer wall of the mounting bracket has a guide groove adapted to the vertical guide rod, and when the mounting bracket is installed into the accommodating space, the guide groove and the vertical guide rod form a sliding fit, and the protrusion presses the mounting bracket into the accommodating space.

[0011] With the above-mentioned further configuration, the vertical guide rod of the base accommodating space and the guide groove of the mounting bracket form a sliding fit, providing precise guidance for the assembly of the mounting bracket. The protrusion presses and fixes the mounting bracket in the accommodating space, preventing the mounting bracket from loosening or falling out during use, ensuring the conductivity stability of the jumperless structure, and avoiding circuit failure due to structural loosening.

[0012] A further feature of this invention is that the inner wall of the base is integrally provided with multiple vertical guide rods and protrusions, and the outer wall of the mounting bracket has multiple guide grooves, with a "Λ"-shaped insertion port at the lower end of the guide grooves.

[0013] With the above-mentioned further design, multiple vertical guide rods and protrusions integrally formed on the inner wall of the base enhance structural strength and reduce processing difficulty; multiple guide slots of the mounting bracket are matched one by one with the vertical guide rods, further improving assembly guidance accuracy; the "Λ" shaped insertion port facilitates the quick insertion of the guide rod into the guide slot, simplifies assembly operations, improves assembly efficiency, and ensures structural stability after installation, providing reliable structural support for jumperless conductive solutions.

[0014] A further feature of this invention is that the switch can be a single switch or a multi-position switch, and each switch button is configured with a set of conductive on / off components.

[0015] With the above-mentioned further settings, it supports flexible configuration of one or more switches. Each switch button corresponds independently to a set of jumperless conductive on / off components, realizing independent control of multiple circuits and adapting to the electrical equipment control needs of different places such as homes, hotels, and shopping malls. Each set of components has the same structure and does not require jumpers, which not only expands the application range of switches, but also facilitates mass production and unified maintenance, reducing subsequent maintenance costs.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1-9As shown, this utility model discloses a multi-control switch, including a base 1, a push plate 2, a switch button 3 that can be pressed by the push plate, and a conductive switching assembly 4. The switch button 3 has a first lever 31 and a second lever 32, and the switch button 3 corresponds to a set of conductive switching assemblies 4. The conductive switching assembly 4 includes a first inlet terminal 41, a first outlet terminal 42, a second inlet terminal 43 and a second outlet terminal 44, a first conductive support plate 45 and a second conductive support plate 46 respectively connected to the two inlet terminals, a first stationary contact bridge 47 and a second stationary contact bridge 48 respectively connected to the two outlet terminals, and a first moving contact bridge 49 and a second moving contact bridge 40 respectively linked to the two levers of the switch button 3. The first conductive support plate 45 is connected to... A first incoming terminal is connected to a second incoming terminal, a second conductive support plate 46 is connected to a second incoming terminal, a first stationary contact bridge 47 is connected to a first outgoing terminal, a second stationary contact bridge 48 is connected to a second outgoing terminal, a first moving contact bridge 49 is linked with a first lever 31 of a switch button 3, and a second moving contact bridge 40 is linked with a second lever 32 of a switch button 3. The first stationary contact bridge 47 and the second stationary contact bridge 48 extend towards each other to form a first contact piece 471 and a second contact piece 481, respectively. The first contact piece 471 is integrally connected to the first stationary contact bridge 47, and the first contact piece 471 is located above the second stationary contact bridge 48; the second contact piece 481 is integrally connected to the second stationary contact bridge 48, and the second contact piece 481 is located above the first stationary contact bridge 47.

The second contact piece 481 and the first stationary contact bridge 47 are respectively provided with a first stationary contact 482 and a second stationary contact 472 adapted to the corresponding movable contact.

The upper and lower end faces of the second movable contact bridge 40 are respectively provided with a third movable contact 401 and a fourth movable contact 402. The first contact piece 471 and the second stationary contact bridge 48 are respectively provided with a third stationary contact 473 and a fourth stationary contact 483 adapted to the corresponding movable contact. The switch button 3 drives the first moving contact bridge 49 and the second moving contact bridge 40 to swing up and down synchronously, so that the moving contacts of the two moving contact bridges alternately contact the corresponding stationary contacts, thereby realizing the switching on and off of the two sets of circuits.

[0020] Specifically, the base 1 is equipped with a mounting bracket 5, which has multiple pressing feet 51 extending downwards integrally; each inlet terminal and outlet terminal is provided with a positioning post 411 at its upper end, and each conductive support piece and stationary contact bridge is provided with a positioning hole 412. The positioning hole 412 is adapted to be inserted and positioned with the positioning post 411, and each conductive support piece and stationary contact bridge is pressed against the upper surface of the corresponding inlet terminal and outlet terminal by the corresponding pressing foot 51.

[0021] The base is equipped with multiple terminal slots, and each incoming and outgoing terminal is fixed in the terminal slot with screws to ensure the stability of the terminal position.

[0022] Specifically, each end of the switch button 3 is equipped with a pry bar 6. Both the switch button 3 and the pry bar 6 are rotatably mounted on the mounting bracket 5. One end of the pry bar 6 is provided with a pressure head 61 that is pressed by the button plate 2, and the other end is provided with a pair of drive rods 62 that respectively abut against the two levers of the switch button 3. When either end of the button plate 2 is pressed, it can drive the pry bar 6 at the corresponding end to rotate, thereby pushing the switch button 3 to swing to control the switch on and off. The switch button has a rotating shaft at both ends, and the mounting bracket has corresponding shaft holes. The rotating shaft is inserted into the shaft holes to realize the rotational assembly of the switch button. The pry bar has a pin in the middle, and the mounting bracket has a pin seat. The pin and the pin seat cooperate to realize the rotational assembly of the pry bar.

[0023] Specifically, the base 1 has an internal accommodating space 11, and the inner wall of the base 1 is provided with vertical guide rods 12 and protrusions 13. The outer wall of the mounting bracket 5 has guide grooves 52 adapted to the vertical guide rods 12. When the mounting bracket 5 is inserted into the accommodating space 11, the guide grooves 52 and the vertical guide rods 12 form a sliding fit, and the protrusions 13 press the mounting bracket 5 into the accommodating space 11. Specifically, the inner wall of the base 1 is integrally provided with multiple vertical guide rods 12 and protrusions 13, and the outer wall of the mounting bracket 5 has multiple guide grooves 52, with a "Λ"-shaped insertion port 521 at the lower end of the guide grooves 52.

[0024] Specifically, the switch can be a single switch or a multi-position switch, and each switch button 3 is configured with a set of conductive on / off components 4.

[0025] The working principle of this utility model is as follows: 1. Assembly stage: The first incoming terminal, first outgoing terminal, second incoming terminal, and second outgoing terminal of the conductive switching component are installed in the accommodating space of the base, and no additional jumper wires are required for each terminal. The first conductive support plate and the second conductive support plate are respectively connected to the two incoming terminals, and the first stationary contact bridge and the second stationary contact bridge are respectively connected to the two outgoing terminals. They are positioned by inserting the positioning pins of the terminals through the positioning holes. When the mounting bracket is assembled to the base, the guide groove slides into the accommodating space along the vertical guide rod, and the protrusion presses the mounting bracket in place. The pressure feet of the mounting bracket simultaneously press against each conductive support plate and the stationary contact bridge to ensure that the components are reliably fixed. The switch button and the pry bar are rotatably assembled on the mounting bracket. The pair of drive rods of the pry bar correspond to the two levers of the switch button. After the mounting plate is assembled, its bottom surface corresponds to the pressure head of the pry bar, completing the overall assembly (no jumper wire operation is required throughout the process).

[0026] 2. On / off control phase: When one end of the button is pressed, the button rotates and presses down on the pressure head of the corresponding end pry bar. The pry bar rotates around the pin shaft, and its pair of drive rods synchronously push the first lever and the second lever of the switch button, causing the switch button to swing around the pivot. When the switch button swings, the first lever and the second lever respectively drive the first moving contact bridge to make contact with the second contact piece, and the second moving contact bridge to make contact with the first contact piece. When the other end of the button is pressed, the button rotates and presses down on the pressure head of the corresponding end pry bar. The pry bar also rotates around the pin shaft, and its pair of drive rods synchronously push the second lever and the first lever of the switch button, causing the switch button to swing in opposite directions around the axis of rotation. When the switch button swings, the first lever and the second lever respectively drive the first moving contact bridge and the first stationary contact bridge to make contact, and the second moving contact bridge and the second stationary contact bridge to make contact.

[0027] This product conducts current entirely through cross contacts, eliminating the need for additional jumpers, and the two moving contact bridges always operate synchronously, ensuring precise and consistent circuit switching.

[0028] When this product is a multi-position switch, each switch button corresponds to an independent set of jumperless conductive on / off components. A single-position switch has one button, and a two-position switch has two buttons. Pressing different buttons can independently drive the corresponding switch button and conductive on / off components. The on / off logic of each circuit is the same as that of a single-position switch, and they do not interfere with each other. This meets the control needs of multiple locations for the same electrical equipment or multiple sets of electrical equipment. Moreover, the entire process is jumperless, making installation and maintenance convenient.

[0029] It should be noted that in the description of this utility model, all directional indicators (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
