Description

Technical Field

[0001] This application relates to the field of switch technology, and more particularly to a multi-control switch. Background Technology

[0002] A multi-control switch, also known as a "intermediate switch" or "intermediate switch," allows the switching on and off of a circuit to be controlled from three or more locations, adjusting the electrical connection between the load and the power supply.

[0003] A multi-control switch includes an electrical contact assembly and a conductive assembly. The electrical connection between the load and the power supply can be achieved through the cooperation of the contact assembly and the conductive assembly.

[0004] Due to the existing structure of contact and conductive components, multi-control switches are relatively large and have high manufacturing costs. Utility Model Content

[0005] This application provides a multi-control switch that can reduce the size of the multi-control switch, thereby reducing the manufacturing cost of the multi-control switch.

[0006] In a first aspect, this application provides a multi-control switch. The multi-control switch includes a housing, an inlet stationary contact group, an outlet stationary contact group, a moving contact group, an outlet terminal group, a first connecting assembly, and a second connecting assembly. The inlet stationary contact group is fixedly installed to the housing. The outlet stationary contact group is fixedly installed to the housing and electrically connected to the inlet stationary contact group via the first connecting assembly. The moving contact group is movably installed to the housing, positioned between the inlet and outlet stationary contact groups, and electrically connected to either the inlet or outlet stationary contact groups. The outlet terminal group is fixedly installed to the housing, located on the side of the outlet stationary contact group opposite to the inlet stationary contact group, and electrically connected to an outlet wire. One end of the second connecting assembly is connected to the moving contact group, and the other end of the second connecting assembly is connected to the outlet terminal group. The second connecting component is approximately parallel to the first connecting component, and both the second connecting component and the first connecting component are perpendicular to the bottom wall of the housing.

[0007] In this example, since the first connecting component connects the incoming stationary contact group and the outgoing stationary contact group (i.e., the first connecting component is parallel to the arrangement direction of the incoming and outgoing stationary contact groups and perpendicular to the bottom wall of the housing), the size of the first connecting component is smaller in the direction perpendicular to the arrangement direction of the outgoing and incoming stationary contact groups and parallel to the bottom wall of the housing. Because the first connecting component is installed in the housing, the size of the housing at the location where the first connecting component is installed in the direction perpendicular to the arrangement direction of the outgoing and incoming stationary contact groups and parallel to the bottom wall of the housing can be reduced. This reduces the material used in the housing, lowers the manufacturing cost of the multi-control switch, makes the installation of internal structural components more compact, and improves the space utilization rate inside the housing.

[0008] Furthermore, since the outgoing terminal group is located on the side of the outgoing stationary contact group opposite to the incoming stationary contact group, and the second connecting component connects the outgoing stationary contact group and the outgoing terminal group, meaning the second connecting component is parallel to the arrangement direction of the outgoing stationary contact group and the outgoing terminal group, and is perpendicular to the bottom wall of the housing, the size of the second connecting component is smaller in the direction perpendicular to the arrangement direction of the outgoing stationary contact group and the outgoing terminal group and parallel to the bottom wall of the housing. Because the second connecting component is installed in the housing, the size of the housing at the location where the second connecting component is installed in the direction perpendicular to the arrangement direction of the outgoing stationary contact group and the outgoing terminal group and parallel to the bottom wall of the housing can be reduced, further reducing the material used in the housing, lowering the manufacturing cost of the multi-control switch, making the installation of internal structural components more compact, and improving the space utilization rate inside the housing.

[0009] Furthermore, in this application example, the incoming stationary contact group, the outgoing stationary contact group, the moving contact group, the outgoing terminal group, the first connecting component, and the second connecting component cooperate to form the internal conductive components of the multi-control switch. Since the first connecting component and the second connecting component can reduce the size along the direction perpendicular to the arrangement direction of the outgoing stationary contact group and the outgoing terminal group and parallel to the bottom wall of the housing, two sets of the internal conductive components provided in this application example can be used simultaneously in the same multi-control switch. This avoids using internal conductive components with different structures in the same multi-control switch, thereby expanding the application range of the multi-control switch while saving design costs and mold-related costs in the manufacturing process of the multi-control switch.

[0010] In some possible implementations, the incoming stationary contact group includes a first incoming stationary contact and a second incoming stationary contact spaced apart. The outgoing stationary contact group includes a first outgoing stationary contact and a second outgoing stationary contact spaced apart, with the direction of the first outgoing stationary contact toward the second outgoing stationary contact being the same as the direction of the first incoming stationary contact toward the second incoming stationary contact. The first connecting assembly includes a first connector and a second connector spaced apart, with one end of the first connector connected to the first incoming stationary contact and the other end connected to the second outgoing stationary contact. One end of the second connector is connected to the second incoming stationary contact and the other end is connected to the first outgoing stationary contact. The first connector and the second connector are located within the space formed by the first incoming stationary contact, the second incoming stationary contact, the first outgoing stationary contact, and the second outgoing stationary contact, and both the first connector and the second connector are perpendicular to the bottom wall of the housing.

[0011] In this application example, since both the first connector and the second connector are arranged perpendicular to the bottom wall of the housing, the dimensions of the first connector and the second connector are smaller along the direction from the first incoming line stationary contact to the second incoming line stationary contact. This reduces the size of the housing along the direction from the first incoming line stationary contact to the second incoming line stationary contact, reduces the material used in the housing, lowers the manufacturing cost of the multi-control switch, makes the installation of the internal structural components of the housing more compact, and improves the space utilization rate inside the housing.

[0012] Furthermore, the first connector connects the first incoming stationary contact to the second outgoing stationary contact, and the second connector connects the second incoming stationary contact to the first outgoing stationary contact. Both the first and second connectors are located within the space enclosed by the first incoming stationary contact, the second incoming stationary contact, the first outgoing stationary contact, and the second outgoing stationary contact. This allows the connection between the first incoming stationary contact and the second outgoing stationary contact to be achieved using a shorter first connector, and the connection between the second incoming stationary contact and the first outgoing stationary contact to be achieved using a shorter second connector, thereby reducing the manufacturing cost of the multi-control switch.

[0013] In some possible implementations, the first connector is located on the side of the second connector facing away from the bottom wall, or the second connector is located on the side of the first connector facing away from the bottom wall. Along the direction from the first connector to the bottom wall, the projection of the first connector substantially falls within the projection range of the second connector.

[0014] In this application example, regardless of whether the first connector is located on the side of the second connector away from the bottom wall of the housing, or the second connector is located on the side of the first connector away from the bottom wall of the housing, the projection of the first connector basically falls within the projection range of the second connector along the direction of the first connector toward the bottom wall of the housing. That is, the first connector and the second connector basically coincide, making the dimensions of the first connector and the second connector smaller in the direction from the first incoming line stationary contact to the second incoming line stationary contact. This further reduces the dimensions of the housing where the first connecting assembly is installed in the direction from the first incoming line stationary contact to the second incoming line stationary contact, reduces the material used in the housing, lowers the manufacturing cost of the multi-control switch, makes the installation of the internal structural components of the housing more compact, and improves the space utilization rate inside the housing.

[0015] In some possible implementations, the housing has a first mounting slot and a second mounting slot that are connected to each other. The first mounting slot and the second mounting slot are arranged perpendicular to the bottom wall. The first mounting slot is used to install the first connector, and the second mounting slot is used to install the second connector.

[0016] In this example, a first mounting slot and a second mounting slot are disposed on the housing, and the first and second mounting slots are arranged perpendicular to the bottom wall of the housing. The first mounting slot is used to install a first connecting member, and the second mounting slot is used to install a second connecting member. That is, by setting the first and second mounting slots perpendicular to the bottom wall of the housing, the first and second connecting members can be arranged perpendicular to the bottom wall of the housing. Furthermore, the first mounting slot can limit the movement of the first connecting member, reducing the amplitude of its wobbling during the use of the multi-control switch. The second mounting slot can also limit the movement of the second connecting member, reducing its wobbling during the use of the multi-control switch and ensuring the reliability of the multi-control switch.

[0017] In some possible implementations, the second connector includes a connecting body, which is bent toward the second incoming stationary contact to form a first bent portion that connects to the second incoming stationary contact. A first insulating rib is provided between the first bent portion and the first connector. Alternatively, the connecting body may be bent toward the first outgoing stationary contact to form a second bent portion that connects to the first outgoing stationary contact. A second insulating rib is provided between the second bent portion and the first connector.

[0018] In this example, the connecting body is part of the second connector. The connecting body forms a first bend towards the second incoming stationary contact, resulting in a larger distance between the first bend and the first connector. Since the first bend is part of the second connector, by setting the first bend, the distance between the second connector and the first connector at the end near the second incoming stationary contact can be increased, thereby increasing the electrical clearance between the two connectors and reducing the possibility of a short circuit between them. Furthermore, a first insulating rib is provided between the first bend and the first connector, which can further increase the electrical clearance between the two connectors, reducing the possibility of a short circuit and ensuring the reliability of the multi-control switch.

[0019] The connecting body forms a second bend towards the first outgoing stationary contact, resulting in a larger distance between the second bend and the first connecting member. Since the second bend is part of the second connecting member, it allows for a larger gap between the second connecting member and the first connecting member at the end closest to the first outgoing stationary contact, increasing the electrical clearance between them and reducing the possibility of a short circuit. Furthermore, a second insulating rib is provided between the second bend and the first connecting member, further increasing the electrical clearance and reducing the likelihood of a short circuit, thus ensuring the reliability of the multi-control switch.

[0020] In some possible implementations, the moving contact group includes a first moving contact and a second moving contact. One end of the first moving contact is in contact with the first incoming stationary contact, and one end of the second moving contact is in contact with the second incoming stationary contact. Alternatively, the other end of the first moving contact is in contact with the first outgoing stationary contact, and the other end of the second moving contact is in contact with the second outgoing stationary contact.

[0021] The second connecting assembly includes a third connector and a fourth connector. One end of the third connector contacts the first moving contact, and the other end of the third connector is connected to the first outgoing terminal in the outgoing terminal group. A portion of the third connector is located on the side of the first moving contact opposite to the second moving contact. One end of the fourth connector contacts the second moving contact, and the other end of the fourth connector is connected to the second outgoing terminal in the outgoing terminal group. A portion of the fourth connector is located on the side of the second moving contact opposite to the first moving contact.

[0022] In this application example, the third connector connects the first moving contact to the first outgoing terminal, and the fourth connector connects the second moving contact to the second outgoing terminal. Therefore, the electrical connection between the moving contact group and the outgoing terminal group can be realized through the third connector and the fourth connector, and then the electrical connection between the multi-control switch and the outgoing wire can be realized through the outgoing terminal group.

[0023] Since some of the third connecting parts are located on the side of the first moving contact away from the second moving contact, and some of the fourth conductive parts are located on the side of the second moving contact away from the first moving contact, that is, the third connecting parts and the fourth connecting parts are at least partially spaced apart, the possibility of short circuit between the third connecting parts and the fourth connecting parts can be reduced, and the reliability of the multi-control switch can be guaranteed.

[0024] In some possible implementations, the housing is provided with a third mounting groove and a fourth mounting groove. The third mounting groove is located on the side of the first moving contact opposite to the second moving contact and is used to mount a third connector. A portion of the groove wall is located between the third connector and the first moving contact. The fourth mounting groove is located on the side of the second moving contact opposite to the first moving contact and is used to mount a fourth connector. A portion of the groove wall is located between the fourth connector and the second moving contact.

[0025] In this application example, both the third and fourth mounting slots are located within the housing. The third mounting slot provides mounting space for the third connector. The fit between the slot wall and the third connector reduces the amplitude of the third connector's movement relative to the housing, thus ensuring reliable connection between the first outgoing stationary contact and the first outgoing terminal. Similarly, the fourth mounting slot provides mounting space for the fourth connector. The fit between the slot wall and the fourth connector reduces the amplitude of the fourth connector's movement relative to the housing, ensuring reliable connection between the second outgoing stationary contact and the second outgoing terminal.

[0026] In some possible implementations, the side of the third connector closest to the first moving contact is a first arc surface, which contacts the first moving contact. And / or, the side of the fourth connector closest to the second moving contact is a second arc surface, which contacts the second moving contact.

[0027] In this example, by setting the contact surface between the third connector and the first moving contact to a first arc surface, the contact area between the third connector and the first moving contact is larger. Furthermore, during the rotation of the first moving contact relative to the third connector, the contact area between the first moving contact and the third connector is relatively stable. This reduces the possibility of current erosion at the first moving contact and the third connector due to the large instantaneous current when the load enters the working state during the use of the multi-control switch, thus ensuring the performance of the multi-control switch.

[0028] By setting the contact surface between the fourth connector and the second moving contact to a second arc surface, the contact area between the fourth connector and the second moving contact is larger. Furthermore, during the rotation of the second moving contact relative to the fourth connector, the contact area between the second moving contact and the fourth connector remains relatively stable. This reduces the possibility of current erosion at the second moving contact and the fourth connector due to a large instantaneous current when the load enters the working state during the use of the multi-control switch, thus ensuring the performance of the multi-control switch.

[0029] In some possible implementations, the multi-control switch also includes a toggle member, the housing includes a mating base and a panel, the panel is movable relative to the base, the first moving contact includes a first moving contact plate, the first moving contact plate is movably mounted to the base, the side of the first moving contact plate opposite to the base is provided with a sliding groove, one end of the toggle member is connected to the panel, and the other end of the toggle member is connected to the groove wall of the sliding groove, the panel can drive the toggle member to slide relative to the groove wall of the sliding groove, so that one end of the first moving contact contacts the first incoming stationary contact, or the other end of the first moving contact contacts the first outgoing stationary contact.

[0030] In this example, the panel is movable relative to the base, and the panel can drive the toggle member to slide within the sliding groove. Since the sliding groove is located on the first movable contact plate, when the toggle member is located at different positions within the sliding groove, the force applied to the first movable contact plate through the groove wall is different, thereby enabling the first movable contact plate to switch between contacting the first outgoing stationary contact and contacting the first incoming stationary contact, thus realizing the switching of the multi-control switch between the on and off states.

[0031] In some possible implementations, the first outgoing terminal includes an adjusting screw, a terminal block, and a terminal frame. The adjusting screw is movably mounted to the housing. The terminal block is fixedly mounted to the housing. The terminal frame is movably mounted to the housing. The adjusting screw is threadedly connected to the terminal frame, and the terminal frame mates with the terminal block to form a wiring port. The adjusting screw causes the terminal frame to slide relative to the terminal block to adjust the opening size of the wiring port.

[0032] Compared to the prior art where screws are used to clamp the outgoing wires with the frame wall of the terminal block, in this application example, an adjusting screw is movably installed in the housing, and the adjusting screw can drive the terminal block to move relative to the terminal block. The terminal block and the terminal block cooperate to form a connection port. That is, when the first outgoing terminal is connected to the outgoing wire, the frame wall of the terminal block and the terminal block cooperate to clamp the outgoing wire, thereby increasing the contact area between the first outgoing terminal and the outgoing wire, reducing the possibility of damage to the outgoing wire during the use of the multi-control switch, and ensuring the reliability of the multi-control switch.

It will be explicitly and implicitly understood by those skilled in the art that the examples described herein can be combined with other examples.

[0046] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists, A and B exist simultaneously, or B exists. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0047] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the multi-control switch in this application.

[0051] For example, this application provides a multi-control circuit system. This system allows control of electrical appliances electrically connected to it from three or more locations, enabling the appliances to switch between an off state and an on state. The appliances can be lights, televisions, etc.

[0052] The multi-control circuit system includes a first double-control switch, a second double-control switch, and at least one multi-control switch electrically connected. One of the first and second double-control switches is electrically connected between the multi-control switch and the incoming wire, while the other is electrically connected between the multi-control switch and the outgoing wire. The multi-control circuit system is electrically connected between the neutral wire and the live wire via the incoming and outgoing wires.

[0053] The specific method of electrical connection between the first double-control switch, the multi-control switch and the second double-control switch is similar to the electrical connection method between the first double-control switch, the multi-control switch and the second double-control switch in the prior art, and will not be described in detail here.

[0054] Since the multi-control circuit system provided in this application example includes the multi-control switch described below, the multi-control circuit provided in this application example has the same effects as the multi-control switch described below.

[0055] Next, this application provides a detailed description of the specific structure of a multi-control switch.

[0056] To enable those skilled in the art to better understand the present application, the multi-control switch provided in the example of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0057] For example, this application provides a multi-control switch. Figure 1 This application provides a partial structural schematic diagram of a multi-control switch as an example. Figure 2 This is a schematic diagram of the internal conductive component of a multi-control switch, provided as an example of this application.

[0058] Please refer to Figure 1 and Figure 2 The multi-control switch 100 includes a housing 110, an inlet stationary contact group 120, an outlet stationary contact group 130, a moving contact group 150, an outlet terminal group 160, a first connecting assembly 140, and a second connecting assembly 170. The inlet stationary contact group 120 is fixedly mounted to the housing 110. The outlet stationary contact group 130 is fixedly mounted to the housing 110 and is electrically connected to the inlet stationary contact group 120 via the first connecting assembly 140. The moving contact group 150 is movably mounted to the housing 110 and is located between the inlet stationary contact group 120 and the outlet stationary contact group 130. The moving contact group 150 is electrically connected to the inlet stationary contact group 120 or electrically connected to the outlet stationary contact group 130. The outgoing terminal assembly 160 is fixedly installed to the housing 110. The outgoing terminal assembly 160 is located on the side of the outgoing stationary contact assembly 130 opposite to the incoming stationary contact assembly 120, and is electrically connected to the outgoing wire. One end of the second connecting assembly 170 is connected to the moving contact assembly 150, and the other end of the second connecting assembly 170 is connected to the outgoing terminal assembly 160. The second connecting assembly 170 is approximately parallel to the first connecting assembly 140, and both the second connecting assembly 170 and the first connecting assembly 140 are perpendicular to the bottom wall of the housing 110.

[0059] The housing 110 is made of insulating material, such as polyvinyl chloride or polycarbonate (also known as PC plastic). The housing 110 made of insulating material can reduce the possibility of current escaping from the housing 110 to the outside, ensuring the safety of the multi-control switch 100.

[0060] The incoming stationary contact group 120, the outgoing stationary contact group 130, the moving contact group 150, the outgoing terminal group 160, the first connecting component 140, and the second connecting component 170 cooperate to form the internal conductive components of the multi-control switch 100, and are connected to the outgoing wire through the outgoing terminal group 160.

[0061] Both the incoming stationary contact group 120 and the outgoing stationary contact group 130 are fixedly connected to the bottom wall of the housing 110 by means of threaded connection, riveting, etc. The incoming stationary contact group 120 includes multiple incoming stationary contacts spaced apart. The minimum electrical clearance between two adjacent incoming stationary contacts is greater than or equal to 3 mm to ensure that the electrical clearance between different incoming stationary contacts meets standard requirements, reducing the possibility of short circuit between adjacent incoming stationary contacts and ensuring the reliability of the multi-control switch 100. The incoming stationary contact group 120 is electrically connected to the incoming wire through the incoming terminal group 180. The number of incoming terminals in the incoming terminal group 180 is equal to the number of incoming stationary contacts, and the incoming terminals in the incoming terminal group 180 correspond one-to-one with the incoming stationary contacts. The incoming terminals can be screw-type terminals, pull-tab terminals, or other types of terminals; this application example does not impose specific limitations on this.

[0062] One end of the first connecting component 140 is connected to the incoming stationary contact group 120, and the other end of the first connecting component 140 is connected to the outgoing stationary contact group 130. The number of connectors in the first connecting component 140 is equal to the number of outgoing stationary contacts in the outgoing stationary contact group 130, and they correspond one-to-one.

[0063] The number of outgoing stationary contacts in the outgoing stationary contact group 130 is equal to and corresponds one-to-one with the number of outgoing stationary contacts in the incoming stationary contact group 120. The arrangement of the outgoing stationary contact group 130 is similar to that of the incoming stationary contact group 120. This example will not be described in detail here.

[0064] The outgoing stationary contact group 130 is connected to the outgoing terminal group 160 via the second connecting assembly 170, and is connected to the outgoing wire via the outgoing terminal group 160. The number of outgoing terminals in the outgoing terminal group 160 is equal to the number of outgoing stationary contacts in the outgoing stationary contact group 130, and the incoming terminals in the outgoing terminal group 160 correspond one-to-one with the outgoing stationary contacts. The outgoing terminals can be screw-type terminals, pull-tab terminals, or other types of terminals; this application example does not impose specific limitations on this.

[0065] The multiple connectors in the first connecting assembly 140 are spaced apart, and the minimum electrical clearance between different connectors in the first connecting assembly 140 is greater than or equal to 3 mm, so that the electrical clearance between different connectors meets the standard requirements, reduces the possibility of short circuit between different connectors, and ensures the reliability of the multi-control switch 100.

[0066] The moving contact group 150 includes multiple moving contacts, the number of which is equal to the sum of the number of outgoing stationary contacts and the number of incoming stationary contacts. The moving contact group 150 can be electrically connected to the incoming stationary contact group 120, and can also be electrically connected to the outgoing stationary contact group 130, so that the multi-control switch 100 can switch between open and closed states, thereby switching the appliance between a closed state and an operating state. The moving contact group 150 can be a rocker-type moving contact, a swashplate-type moving contact, or other forms of moving contact; this application example does not limit the specific implementation of the moving contact.

[0067] The second connecting component 170 is approximately parallel to the first connecting component 140. This can be understood as the multiple connectors in the second connecting component 170 being approximately parallel, and the connectors in the second connecting component 170 being approximately parallel to the connectors in the first component. "Approximately parallel" can be understood as the included angle formed by the two connectors being less than or equal to 5°.

[0068] Both the second connecting component 170 and the first connecting component 140 are arranged perpendicular to the bottom wall of the housing 110. Taking the second connecting component 170 being arranged perpendicular to the bottom wall of the housing 110 as an example, it can be understood that the long side of the cross-section of the connector in the second connecting component 170 is arranged perpendicular to the bottom wall of the housing 110.

[0069] In this application example, since the first connecting component 140 connects the incoming stationary contact group 120 and the outgoing stationary contact group 130, that is, the first connecting component 140 is parallel to the arrangement direction of the incoming stationary contact group 120 and the outgoing stationary contact group 130, and the first connecting component 140 is perpendicular to the bottom wall of the housing 110, the size of the first connecting component 140 is smaller in the direction perpendicular to the arrangement direction of the outgoing stationary contact group 130 and the incoming stationary contact group 120 and parallel to the bottom wall of the housing 110. Because the first connecting component 140 is installed in the housing 110, the size of the housing 110 at the location where the first connecting component 140 is installed can be reduced in the direction perpendicular to the arrangement direction of the outgoing stationary contact group 130 and the incoming stationary contact group 120 and parallel to the bottom wall of the housing 110. This reduces the material used in the housing 110, lowers the manufacturing cost of the multi-control switch 100, makes the installation of the internal structural components of the housing 110 more compact, and improves the space utilization rate inside the housing 110.

[0070] Furthermore, since the outgoing terminal group 160 is located on the side of the outgoing stationary contact group 130 away from the incoming stationary contact group 120, and the second connecting component 170 connects the outgoing stationary contact group 130 and the outgoing terminal group 160, that is, the second connecting component 170 is parallel to the arrangement direction of the outgoing stationary contact group 130 and the outgoing terminal group 160, and the second connecting component 170 is perpendicular to the bottom wall of the housing 110, the size of the second connecting component 170 is smaller in the direction perpendicular to the arrangement direction of the outgoing stationary contact group 130 and the outgoing terminal group 160 and parallel to the bottom wall of the housing 110. Since the second connecting component 170 is installed on the housing 110, the dimensions of the housing 110 at the location where the second connecting component 170 is installed can be reduced in the direction perpendicular to the arrangement direction of the outgoing stationary contact group 130 and the outgoing terminal group 160 and parallel to the bottom wall of the housing 110. This further reduces the material used in the housing 110, lowers the manufacturing cost of the multi-control switch 100, makes the installation of the internal structural components of the housing 110 more compact, and improves the space utilization rate inside the housing 110.

[0071] Furthermore, in this application example, the incoming stationary contact group 120, the outgoing stationary contact group 130, the moving contact group 150, the outgoing terminal group 160, the first connecting component 140, and the second connecting component 170 cooperate to form the internal conductive elements of the multi-control switch 100. Since the first connecting component 140 and the second connecting component 170 can reduce their dimensions in the direction perpendicular to the arrangement direction of the outgoing stationary contact group 130 and the outgoing terminal group 160 and parallel to the bottom wall of the housing 110, it is possible to use two sets of internal conductive elements provided in this application example in the same multi-control switch 100. This avoids using internal conductive elements with different structures in the same multi-control switch 100, thereby expanding the application range of the multi-control switch 100 while saving design costs and mold-related costs in the manufacturing process of the multi-control switch 100.

[0072] Based on the multi-control switch 100 provided in the above example, please refer to... Figure 2The incoming stationary contact group 120 includes a first incoming stationary contact 121 and a second incoming stationary contact 122 spaced apart. The outgoing stationary contact group 130 includes a first outgoing stationary contact 131 and a second outgoing stationary contact 132 spaced apart, and the direction of the first outgoing stationary contact towards the second outgoing stationary contact 132 is the same as the direction of the first incoming stationary contact 121 towards the second incoming stationary contact 122. The first connecting assembly 140 includes a first connector 141 and a second connector 142 spaced apart. One end of the first connector 141 is connected to the first incoming stationary contact 121, and the other end of the first connector 141 is connected to the second outgoing stationary contact 132. One end of the second connector 142 is connected to the second incoming stationary contact 122, and the other end of the second connector 142 is connected to the first outgoing stationary contact 131. The first connector 141 and the second connector 142 are located within the space formed by the first incoming stationary contact 121, the second incoming stationary contact 122, the first outgoing stationary contact 131, and the second outgoing stationary contact 132, and both the first connector 141 and the second connector 142 are arranged perpendicular to the bottom wall of the housing 110.

[0073] The first incoming stationary contact 121, the second incoming stationary contact 122, the first outgoing stationary contact 131, and the second outgoing stationary contact 132 have similar structures. Taking the first incoming stationary contact 121 as an example, the first incoming stationary contact 121 includes a first incoming stationary contact point and a first incoming stationary contact plate that are connected to each other.

[0074] One end of the first connector 141 is connected to the first incoming stationary contact 121, and the other end of the first connector 141 is connected to the second outgoing stationary contact 132. The first connector 141, the first incoming stationary contact plate, and the second outgoing stationary contact 132 can be fixedly connected by welding, threaded connection, snap-fit, or other methods, or they can be integrally formed. One end of the second connector 142 is connected to the second incoming stationary contact 122, and the other end of the second connector 142 is connected to the first outgoing stationary contact 131. The second connector 142, the second incoming stationary contact plate in the second incoming stationary contact 122, and the first outgoing stationary contact plate in the first outgoing stationary contact 131 can be fixedly connected by welding, threaded connection, snap-fit, or other methods, or they can be integrally formed. Since the direction of the first incoming stationary contact 121 toward the second incoming stationary contact 122 is the same as the direction of the first outgoing stationary contact 131 toward the second outgoing stationary contact 132, the first incoming stationary contact plate, the first connector 141 and the second outgoing stationary contact plate together form an X-shaped structure.

[0075] The minimum electrical clearance between the structural component formed by the first incoming stationary contact plate, the first connecting member 141, and the second outgoing stationary contact plate, and the structural component formed by the second incoming stationary contact plate, the second connecting member 142, and the first outgoing stationary contact plate, is greater than or equal to 3 mm. This ensures that the electrical clearance between the conductive components inside the multi-control switch 100 meets industry standard requirements, thereby ensuring the safety and reliability of the multi-control switch 100.

[0076] Along a direction perpendicular to the bottom wall of the housing 110, the first connector 141 and the second connector 142 are spaced apart. The first connector 141 may be located on the side of the second connector 142 opposite to the bottom wall of the housing 110, or the second connector 142 may be located on the side of the first connector 141 opposite to the bottom wall of the housing 110. Along a direction perpendicular to the bottom wall of the housing 110, the projections of the first connector 141 and the second connector 142 may be spaced apart or at least partially overlap; this application example does not impose specific limitations in this regard.

[0077] In this application example, since both the first connector 141 and the second connector 142 are arranged perpendicular to the bottom wall of the housing 110, the dimensions of the first connector 141 and the second connector 142 are smaller along the direction from the first incoming line stationary contact 121 to the second incoming line stationary contact 122. This reduces the dimensions of the housing 110 along the direction from the first incoming line stationary contact 121 to the second incoming line stationary contact 122, reduces the material used in the housing 110, lowers the manufacturing cost of the multi-control switch 100, makes the installation of the internal structural components of the housing 110 more compact, and improves the space utilization rate inside the housing 110.

[0078] Furthermore, the first connector 141 connects the first incoming stationary contact 121 and the second outgoing stationary contact 132, and the second connector 142 connects the second incoming stationary contact 122 and the first outgoing stationary contact 131. Both the first connector 141 and the second connector 142 are located within the space enclosed by the first incoming stationary contact 121, the second incoming stationary contact 122, the first outgoing stationary contact 131, and the second outgoing stationary contact 132. This allows the connection between the first incoming stationary contact 121 and the second outgoing stationary contact 132 to be achieved with a shorter first connector 141, and the connection between the second incoming stationary contact 122 and the first outgoing stationary contact 131 to be achieved with a shorter second connector 142, thereby reducing the manufacturing cost of the multi-control switch 100.

[0079] Based on the multi-control switch 100 provided in the above example, Figure 3 for Figure 1 Please refer to the sectional view at point AA. Figures 1-3The first connector 141 is located on the side of the second connector 142 away from the bottom wall, or the second connector 142 is located on the side of the first connector 141 away from the bottom wall. Along the direction from the first connector 141 to the bottom wall, the projection of the first connector 141 basically falls within the projection range of the second connector 142.

[0080] The first connector 141 is disposed on the side of the second connector 142 away from the bottom wall, or the second connector 142 is disposed on the side of the first connector 141 away from the bottom wall. This application example only describes the direction in which the second connector 142 is disposed on the side of the first connector 141 away from the bottom wall of the housing 110.

[0081] Along the direction from the first connector 141 to the bottom wall of the housing 110, that is, along the direction perpendicular to the bottom wall of the housing 110, the projection of the first connector 141 basically falls within the projection range of the second connector 142.

[0082] Along the direction from the incoming stationary contact group 120 toward the outgoing stationary contact group 130, the dimensions of the first connector 141 and the second connector 142 may be equal or unequal, and this application example does not impose specific limitations on this.

[0083] In this application example, regardless of whether the first connector 141 is located on the side of the second connector 142 away from the bottom wall of the housing 110, or the second connector 142 is located on the side of the first connector 141 away from the bottom wall of the housing 110, the projection of the first connector 141 along the direction of the first connector 141 toward the bottom wall of the housing 110 basically falls within the projection range of the second connector 142, that is, the first connector 141 and the second connector 142 basically coincide, making the dimensions of the first connector 141 and the second connector 142 smaller in the direction from the first incoming line stationary contact 121 to the second incoming line stationary contact 122. This can further reduce the dimensions of the housing 110 where the first connecting assembly 140 is installed along the direction from the first incoming line stationary contact 121 to the second incoming line stationary contact 122, reduce the material used in the housing 110, reduce the manufacturing cost of the multi-control switch 100, make the installation of the internal structural components of the housing 110 more compact, and improve the space utilization rate inside the housing 110.

[0084] Based on the multi-control switch 100 provided in the above example, Figure 4 Please refer to the structural schematic diagram of a shell provided as an example in this application. Figures 1-4 The housing 110 has a first mounting groove 111 and a second mounting groove 112 that are connected to each other. The arrangement direction of the first mounting groove 111 and the second mounting groove 112 is perpendicular to the bottom wall. The first mounting groove 111 is used to install the first connector 141, and the second mounting groove 112 is used to install the second connector 142.

[0085] Along the direction from the incoming stationary contact group 120 to the outgoing stationary contact group 130, the dimensions of the first mounting groove 111 and the second mounting groove 112 can be equal or unequal, as long as the first connector 141 can be installed into the first mounting groove 111 and the second connector 142 can be installed into the second mounting groove 112.

[0086] Along the direction of the first connector 141 toward the bottom wall of the housing 110, i.e., along the direction perpendicular to the bottom wall of the housing 110, when the first connector 141 is located on the side of the second connector 142 away from the bottom wall of the housing 110, the first mounting groove 111 is located on the side of the second mounting groove 112 away from the bottom wall of the housing 110. When the second connector 142 is located on the side of the first connector 141 away from the bottom wall of the housing 110, the second mounting groove 112 is located on the side of the first mounting groove 111 away from the bottom wall of the housing 110. The first mounting groove 111 and the second mounting groove 112 are spaced apart, and the minimum electrical clearance between the first mounting groove 111 and the second mounting groove 112 is greater than or equal to 3 mm, so that the electrical clearance between the first connector 141 installed in the first mounting groove 111 and the second connector 142 installed in the second mounting groove 112 meets the requirements of industry standards, ensuring the safety of the multi-control switch 100.

[0087] In this application example, the first mounting groove 111 and the second mounting groove 112 are disposed on the housing 110, and the first mounting groove 111 and the second mounting groove 112 are arranged in a direction perpendicular to the bottom wall of the housing 110. The first mounting groove 111 is used to install the first connector 141, and the second mounting groove 112 is used to install the second connector 142. That is, by setting the first mounting groove 111 and the second mounting groove 112 in a direction perpendicular to the bottom wall of the housing 110, the first connector 141 and the second connector 142 can be arranged in a direction perpendicular to the bottom wall of the housing 110. The first mounting groove 111 can limit the first connector 141, reducing the amplitude of the first connector 141 shaking during the use of the multi-control switch 100. The second mounting groove 112 can limit the second connector 142, reducing the amplitude of the second connector 142 shaking during the use of the multi-control switch 100, thus ensuring the reliability of the multi-control switch 100.

[0088] Based on the multi-control switch 100 provided in the above example, Figure 5 This application provides a schematic diagram illustrating the fit between a second incoming stationary contact, a second connector, and a first outgoing stationary contact. Figure 6 for Figure 1 Please refer to the enlarged view of part A in the middle. Figure 2 , Figure 5 and Figure 6The second connector 142 includes a connector body 1421. The connector body 1421 is bent toward the second incoming stationary contact 122 to form a first bent portion 1422, which is connected to the second incoming stationary contact 122. A first insulating rib 113 is provided between the first bent portion 1422 and the first connector 141. The connector body 1421 is bent toward the first outgoing stationary contact 131 to form a second bent portion 1423, which is connected to the first outgoing stationary contact 131. A second insulating rib 114 is provided between the second bent portion 1423 and the first connector 141.

[0089] Along the direction perpendicular to the bottom wall of the housing 110, the projection of the connecting body 1421 coincides with the projection range of the first connecting member 141.

[0090] The first insulating rib 113 and the second insulating rib 114 can be integrally formed with the housing 110, or they can be connected to the housing 110 by plug-in or other connection methods.

[0091] Since the first incoming stationary contact 121, the second incoming stationary contact 122, the first outgoing stationary contact 131, and the second outgoing stationary contact 132 form a quadrilateral, and the direction from the first incoming stationary contact 121 to the second incoming stationary contact 122 is the same as the direction from the first outgoing stationary contact 131 to the second outgoing stationary contact 132, the second incoming stationary contact 122 and the first outgoing stationary contact 131 are located on the diagonal of this quadrilateral. Based on this, the bending direction of the first bending portion 1422 relative to the connecting body 1421 is opposite to the bending direction of the second bending portion 1423 relative to the connecting body 1421.

[0092] In this application example, the connecting body 1421 is part of the second connector 142. The connecting body 1421 forms a first bend 1422 towards the second incoming stationary contact 122, resulting in a larger distance between the first bend 1422 and the first connector 141. Since the first bend 1422 is part of the second connector 142, by setting the first bend 1422, the distance between the second connector 142 and the first connector 141 at the end near the second incoming stationary contact 122 can be increased, thereby increasing the electrical clearance between the second connector 142 and the first connector 141 and reducing the possibility of a short circuit between the second connector 142 and the first connector 141. Furthermore, a first insulating rib 113 is provided between the first bend 1422 and the first connector 141, which can further increase the electrical clearance between the second connector 142 and the first connector 141, reducing the possibility of a short circuit between the second connector 142 and the first connector 141 and ensuring the reliability of the multi-control switch 100.

[0093] The connecting body 1421 forms a second bend 1423 towards the first outgoing stationary contact 131, resulting in a larger distance between the second bend 1423 and the first connecting member 141. Since the second bend 1423 is part of the second connecting member 142, its placement allows for a larger distance between the second connecting member 142 and the first connecting member 141 at the end closest to the first outgoing stationary contact 131. This increases the electrical clearance between the two members, reducing the likelihood of a short circuit. Furthermore, a second insulating rib 114 is provided between the second bend 1423 and the first connecting member 141, further increasing the electrical clearance and reducing the possibility of a short circuit, thus ensuring the reliability of the multi-control switch 100.

[0094] Based on the multi-control switch 100 provided in the above example, please refer to... Figure 2 The moving contact group 150 includes a first moving contact 151 and a second moving contact 152. One end of the first moving contact 151 is in contact with the first incoming stationary contact 121, and one end of the second moving contact 152 is in contact with the second incoming stationary contact 122. Alternatively, the other end of the first moving contact 151 is in contact with the first outgoing stationary contact 131, and the other end of the second moving contact 152 is in contact with the second outgoing stationary contact 132.

[0095] The second connection assembly 170 includes a third connector 171 and a fourth connector 172. One end of the third connector 171 contacts the first moving contact 151, and the other end of the third connector 171 is connected to the first outgoing terminal 161 in the outgoing terminal group 160. A portion of the third connector 171 is located on the side of the first moving contact 151 opposite to the second moving contact 152. One end of the fourth connector 172 contacts the second moving contact 152, and the other end of the fourth connector 172 is connected to the second outgoing terminal 162 in the outgoing terminal group 160. A portion of the fourth connector 172 is located on the side of the second moving contact 152 opposite to the first moving contact 151.

[0096] The first moving contact 151 has a first moving contact and a second moving contact at its two ends. The first moving contact can be connected to the first incoming stationary contact 121, and the second moving contact can be connected to the first outgoing stationary contact 131. The second moving contact 152 has a third moving contact and a fourth moving contact at its two ends. The third moving contact and the first moving contact are located on the side of the moving contact group 150 near the incoming terminal group 180, and the fourth moving contact and the second moving contact are located on the side of the moving contact group 150 near the outgoing terminal group 160. The third moving contact can be connected to the second incoming stationary contact 122, and the fourth moving contact can be connected to the second outgoing stationary contact 132.

[0097] During the use of the multi-control switch 100, the multi-control switch 100 is usually used in conjunction with other switches to adjust the on / off state of the circuit from multiple positions. Since the first moving contact 151 and the second moving contact 152 are fixedly connected, during the use of the multi-control switch 100, the on / off state of the circuit can be adjusted by adjusting the first moving contact to contact the first incoming stationary contact 121 and the third moving contact to contact the second incoming stationary contact 122, or by adjusting the second moving contact to contact the first outgoing stationary contact 131 and the fourth moving contact to contact the second outgoing stationary contact 132, in conjunction with other switches.

[0098] The structure of the second moving contact 152 is similar to that of the first moving contact 151, and their operation is similar. Therefore, the example in this application will not be described in detail here.

[0099] One end of the third connector 171 is connected to the first output terminal 161. The third connector 171 can be fixedly connected to the first terminal block in the first output terminal 161 by welding or other means. The third connector 171 can be integrally formed with the first terminal block in the first output terminal 161. One end of the fourth connector 172 is connected to the second output terminal 162. The fourth connector 172 can be fixedly connected to the second terminal block in the second output terminal 162 by welding or other means. The fourth connector 172 can be integrally formed with the second terminal block in the second output terminal 162.

[0100] In this application example, the third connector 171 connects the first moving contact 151 and the first output terminal 161, and the fourth connector 172 connects the second moving contact 152 and the second output terminal 162. Therefore, the electrical connection between the moving contact group 150 and the output terminal group 160 can be realized through the third connector 171 and the fourth connector 172, and then the electrical connection between the multi-control switch 100 and the output wire can be realized through the output terminal group 160.

[0101] Since some of the third connectors 171 are located on the side of the first moving contact 151 away from the second moving contact 152, and some of the fourth conductive elements are located on the side of the second moving contact 152 away from the first moving contact 151, that is, the third connectors 171 and the fourth connectors 172 are at least partially spaced apart, the possibility of short circuit between the third connectors 171 and the fourth connectors 172 can be reduced, ensuring the reliability of the multi-control switch 100.

[0102] Based on the multi-control switch 100 provided in the above example, please refer to... Figures 1-4The housing 110 is provided with a third mounting groove 115 and a fourth mounting groove 116. The third mounting groove 115 is located on the side of the first moving contact 151 opposite to the second moving contact 152, and is used to install a third connector 171. Part of the groove wall of the third mounting groove 115 is located between the third connector 171 and the first moving contact 151. The fourth mounting groove 116 is located on the side of the second moving contact 152 opposite to the first moving contact 151, and is used to install a fourth connector 172. Part of the groove wall of the fourth mounting groove 116 is located between the fourth connector 172 and the second moving contact 152.

[0103] The third mounting groove 115 is located on the side of the first moving contact 151 away from the second moving contact 152. The third mounting groove 115 can be spaced apart from the side wall of the housing 110 near the first moving contact 151. Part of the groove wall of the third mounting groove 115 can also be integrally formed with the side wall of the housing 110 near the first moving contact 151. This application example does not impose specific limitations on this, as long as the third mounting groove 115 can provide installation space for the third connector 171.

[0104] The fourth mounting groove 116 is located on the side of the second moving contact 152 away from the first moving contact 151. The fourth mounting groove 116 can be spaced apart from the side wall of the housing 110 near the second moving contact 152. Part of the groove wall of the fourth mounting groove 116 can also be integrally formed with the side wall of the housing 110 near the second moving contact 152. This application example does not impose specific limitations on this, as long as the fourth mounting groove 116 can provide installation space for the fourth connector 172.

[0105] In this application example, both the third mounting groove 115 and the fourth mounting groove 116 are located in the housing 110. The third mounting groove 115 provides mounting space for the third connector 171. The cooperation between the groove wall of the third mounting groove 115 and the third connector 171 reduces the amplitude of the third connector 171's wobbling relative to the housing 110, thus ensuring the reliable connection between the first outgoing stationary contact 131 and the first outgoing terminal 161. The fourth mounting groove 116 provides mounting space for the fourth connector 172. The cooperation between the groove wall of the fourth mounting groove 116 and the fourth connector 172 reduces the amplitude of the fourth connector 172's wobbling relative to the housing 110, thus ensuring the reliable connection between the second outgoing stationary contact 132 and the second outgoing terminal 162.

[0106] In some possible implementations, both the third mounting groove 115 and the fourth mounting groove 116 have limiting protrusions on their groove walls. The cooperation between the groove wall of the third mounting groove 115 and the limiting protrusions minimizes the amount of wobbling of the third connector 171 relative to the groove wall, thus ensuring a more reliable connection between the first outgoing stationary contact 131 and the first outgoing terminal 161, guaranteeing the reliability of the multi-control switch 100. Similarly, the cooperation between the groove wall of the fourth mounting groove 116 and the limiting protrusions minimizes the amount of wobbling of the fourth connector 172 relative to the groove wall, thus ensuring a more reliable connection between the second outgoing stationary contact 132 and the second outgoing terminal 162, guaranteeing the reliability of the multi-control switch 100.

[0107] Based on the multi-control switch 100 provided in the above example, Figure 7 Please refer to the schematic diagram illustrating the mating of the first outgoing terminal and the third connector, which serves as an example of this application. Figure 2 and Figure 7 The third connector 171 has a first arc surface 1711 on the side near the first moving contact 151, and the first arc surface 1711 contacts the first moving contact 151. And / or, the fourth connector 172 has a second arc surface on the side near the second moving contact 152, and the second arc surface contacts the second moving contact 152.

[0108] The first arc surface 1711 can be formed by bending the end of the third connector 171 near the first moving contact 151, or it can be a polished arc surface. This application example does not impose specific limitations on this. The first arc surface 1711 can directly abut against the first moving contact 151. The first moving contact 151 can also be provided with a groove structure. The first arc surface 1711 can be located in the groove structure and rotate relative to the groove structure.

[0109] The second arc surface can be formed by bending the end of the fourth connector 172 near the second moving contact 152, or it can be formed by grinding. This application example does not specifically limit this.

[0110] In the solution provided in this application example, only the part where the third connector 171 contacts the first moving contact 151 can be set as the first arc surface 1711, or only the part where the fourth connector 172 contacts the second moving contact 152 can be set as the second arc surface, or the position where the third connector 171 contacts the first moving contact 151 can be set as the first arc surface 1711 and the position where the fourth connector 172 contacts the second moving contact 152 can be set as the second arc surface. This application example does not impose specific limitations on this.

[0111] In this application example, by setting the contact surface between the third connector 171 and the first moving contact 151 to a first arc surface 1711, the contact area between the third connector 171 and the first moving contact 151 is larger. During the rotation of the first moving contact 151 relative to the third connector 171, the contact area between the first moving contact 151 and the third connector 171 is relatively stable. During the use of the multi-control switch 100, the possibility of current erosion at the first moving contact 151 and the third connector 171 due to the large instantaneous current when the load enters the working state is reduced, thus ensuring the performance of the multi-control switch 100.

[0112] By setting the contact surface between the fourth connector 172 and the second moving contact 152 to a second arc surface, the contact area between the fourth connector 172 and the second moving contact 152 is larger. During the rotation of the second moving contact 152 relative to the fourth connector 172, the contact area between the second moving contact 152 and the fourth connector 172 is relatively stable. During the use of the multi-control switch 100, the possibility of current erosion at the second moving contact 152 and the fourth connector 172 due to the large instantaneous current when the load enters the working state is reduced, thus ensuring the performance of the multi-control switch 100.

[0113] The connection between the first moving contact 151 and the housing 110 is similar to the connection between the second moving contact 152 and the housing 110. Hereinafter, the connection between the first moving contact 151 and the housing 110 and the connection between the second moving contact 152 and the housing 110 will be described by way of example, taking the connection between the first moving contact 151 and the housing 110 as an example.

[0114] Taking the third connector 171 and the first terminal block as an example of integral molding, the third connector 171 and the first terminal block can be formed by bending and stamping a single plate structure. After unfolding, the third connector 171 and the first terminal block are located in the same plate structure, as shown in the following example. Figure 8 As shown, Figure 8 The provided example is a schematic diagram of a third connector, which can reduce the stamping waste generated during the stamping process of forming the third connector 171 and the first terminal block from the plate structure, reduce the manufacturing cost of the third connector 171 and the first terminal block, and thus reduce the manufacturing cost of the multi-control switch 100.

[0115] The multi-control switch 100 also includes a toggle element 190. Figure 9 For a structural schematic diagram of a first movable contact plate provided as an example of this application, please refer to... Figure 2 and Figure 9The housing 110 includes a base and a panel that cooperate with each other. The panel is movable relative to the base. The first movable contact 151 includes a first movable contact plate 1511. The first movable contact plate 1511 is movably mounted to the base. The side of the first movable contact plate 1511 opposite to the base is provided with a sliding groove 1512. One end of the actuating member 190 is connected to the panel, and the other end of the actuating member 190 is connected to the groove wall of the sliding groove 1512. The panel can drive the actuating member 190 to slide relative to the groove wall of the sliding groove 1512, so that one end of the first movable contact 151 contacts the first inlet stationary contact 121, or the other end of the first movable contact 151 contacts the first outlet stationary contact 131.

[0116] The first moving contact 151 and the second moving contact 152 have similar structures. The first moving contact 151 includes a first moving contact plate 1511, and the first moving contact and the second moving contact mentioned above are located at different ends of the first moving contact plate. The second moving contact 152 includes a second moving contact plate, and the third moving contact and the fourth moving contact mentioned above are located at different ends of the second moving contact plate.

[0117] The way the base and the panel are matched in this application is similar to the way the base and the panel are matched in the prior art. The example in this application will not be described in detail here.

[0118] The toggle member 190 has a rod-shaped structure, and the side of the toggle member 190 facing the first movable contact plate 1511 is arc-shaped, so that the toggle member 190 can slide in the sliding groove 1512, thereby applying force to the first movable contact plate 1511 through the groove wall of the sliding groove 1512, so that the first movable contact 151 switches between contacting the first incoming stationary contact 121 and contacting the first outgoing stationary contact 131, thereby realizing the switching of the multi-control switch 100 between the on state and the off state.

[0119] The sliding groove 1512 can be a groove formed by bending. The first sliding groove 1512 can also be a groove-shaped structure carved into the first movable contact plate 1511. The first sliding groove 1512 can also be a groove-shaped structure formed by other means. The example of this application does not impose specific restrictions on the forming method of the groove-shaped structure, as long as the sliding groove 1512 can limit the sliding distance of the toggle member 190 relative to the first movable contact plate 1511.

[0120] When the actuating member 190 is positioned in the first sliding groove 1512 near the first incoming stationary contact 121, it applies a force to the first moving contact plate 1511 towards the first incoming stationary contact 121 through the groove wall of the first sliding groove 1512, causing the first moving contact 151 to contact the first incoming stationary contact 121. When the actuating member 190 is positioned in the first sliding groove 1512 near the first outgoing stationary contact 131, it applies a force to the first moving contact plate 1511 towards the first outgoing stationary contact 131 through the groove wall of the first sliding groove 1512, causing the first moving contact 151 to contact the first outgoing stationary contact 131.

[0121] In this example, the panel is movable relative to the base, and the panel can drive the toggle member 190 to slide within the sliding groove 1512. Since the sliding groove 1512 is located on the first movable contact plate 1511, when the toggle member 190 is located at different positions within the sliding groove 1512, the force applied to the first movable contact plate 1511 by the groove wall of the sliding groove 1512 is different, thereby enabling the first movable contact plate 1511 to switch between contacting the first outgoing stationary contact 131 and contacting the first incoming stationary contact 121, thus realizing the switching of the multi-control switch 100 between the on state and the off state.

[0122] The structures of the first outgoing terminal 161 and the second outgoing terminal 162 are similar to those of the first incoming terminal 181 and the second incoming terminal 182 in the incoming terminal group 180. Hereinafter, the structures of the first outgoing terminal 161, the second outgoing terminal 162, and the first incoming terminal 181 and the second incoming terminal 182 in the incoming terminal group 180 will be described by way of example only.

[0123] For example, please refer to Figure 7 The first output terminal 161 includes an adjusting screw 1611, a terminal block 1612, and a terminal frame 1613. The adjusting screw 1611 is movably mounted to the housing 110. The terminal block 1612 is fixedly mounted to the housing 110. The terminal frame 1613 is movably mounted to the housing 110. The adjusting screw 1611 is threadedly connected to the terminal frame 1613. The terminal frame 1613 and the terminal block 1612 cooperate to form a wiring port. The adjusting screw 1611 causes the terminal frame 1613 to slide relative to the terminal block 1612 to adjust the opening size of the wiring port.

[0124] The terminal block 1612 can be connected to the third connector 171 by welding, flexible connection, or other means. The terminal block 1612 and the third connector 171 can also be integrally formed. The terminal block 1612 mentioned here is the first terminal block mentioned above.

[0125] The housing 110 is provided with a plurality of hole-like structures at intervals. The number of hole-like structures is equal to the sum of the number of incoming terminals in the incoming terminal group 180 and the number of outgoing terminals in the outgoing terminal group 160. The positions of the hole-like structures correspond to the positions of the incoming terminals and the outgoing terminals, so as to realize the connection between the incoming wire and the incoming terminal, and the connection between the outgoing wire and the outgoing terminal.

[0126] The cross-section of the outgoing conductor can be circular, rectangular, etc., and this application example does not impose specific restrictions on this.

[0127] Compared to the prior art where screws are used to clamp the lead wires with the frame wall of the terminal block, in this application example, an adjusting screw 1611 is movably installed on the housing 110, and the adjusting screw 1611 can drive the terminal block 1613 to move relative to the terminal plate 1612. The terminal block 1613 and the terminal plate 1612 cooperate to form a connection port. That is, when the first lead terminal 161 is connected to the lead wire, the frame wall of the terminal block 1613 and the terminal plate 1612 cooperate to clamp the lead wire, thereby increasing the contact area between the first lead terminal 161 and the lead wire, reducing the possibility of damage to the lead wire during the use of the multi-control switch 100, and ensuring the reliability of the multi-control switch 100.

[0128] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
