Description

Technical Field

[0001] This utility model relates to a switching switch, and more specifically, to a multi-power switching switch. Background Technology

[0002] In many situations, a main power supply circuit and a backup power supply circuit need to be set up in the power supply circuit. In order to realize the automatic switching between the main power supply circuit and the backup power supply circuit, an automatic transfer switch circuit is often required. An automatic transfer switch circuit is a switching device installed in the line to enable the load circuit to achieve continuous power supply. It is mainly used in dual power supply systems. When one power supply circuit fails, the load circuit is automatically switched from one power supply to the other power supply to achieve the purpose of continuous power supply to the load circuit.

[0003] Existing changeover switches are usually based on mechanical structures. The mechanical mechanism inside controls the switching of contacts to the other end. The direction of movement of the mechanical structure can only be up and down. During repeated operation, the mechanical components such as springs and linkages inside the mechanical switch will undergo elastic deformation. With the increase of the number of uses, these components will experience mechanical fatigue, which will cause changes in the operating characteristics of the switch, such as slower switching speed and insufficient contact pressure, thus affecting the normal operation of the switch.

[0004] Other systems use electronic switches, which are susceptible to electromagnetic interference, potentially leading to malfunctions or performance degradation. Electronic switches also typically require an external power supply, increasing the system's energy consumption and complexity.

[0005] Therefore, a stable switching switch needs to be designed. Utility Model Content

It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0030] Reference Figures 1 to 6 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a multi-power switching switch, including a switch assembly 1, a control board 2, a switch button 3 and a magnetic control assembly 4, wherein at least two sets of magnetic control assemblies 4 are provided, and both are installed in the switch assembly 1;

[0031] The control board 2 is connected to the switch button 3 and the magnetic control assembly 4 respectively;

[0032] The switch assembly 1 includes a switch housing 11, an inlet terminal 12, an outlet terminal 13, and a connecting wire group 14;

[0033] Both magnetic control components 4 include a contact component 41, and the first end of the contact component 41 is connected to the first end and the output end 13 of other contact components 41 through the connecting wire group 14.

[0034] Multiple sets of input terminals 12 are provided and should be set one-to-one with the magnetic control components 4. The second end of each contact component 41 is connected to the corresponding input terminal 12.

The magnetic latching relay has no frequent mechanical action, operating only during state switching, and its mechanical lifespan can reach millions of cycles, far exceeding that of ordinary mechanical switches. It eliminates the problem of mechanical contact wear and is less affected by environmental factors such as vibration and impact, making it suitable for harsh environments such as industrial and automotive applications.

[0036] Example 1: The input terminal 12 of the switch assembly 1 is connected to the main power supply and the backup power supply respectively. The switching between the two power supplies can be achieved by opening and closing the magnetic control assembly 4.

[0039] This utility model is further configured such that: limiting grooves 431 are symmetrically provided on the pushing plate 43, and one end of the moving contact 412 is snapped into the limiting groove 431. This structural design, as... Figure 6 As shown, the moving contact 412 is composed of multiple sets of metal plates.

[0042] This invention is further configured such that the switch button 3, the control board 2, and the magnetic control assembly 4 are arranged sequentially along the height direction of the switch housing 11. This structural design improves the arrangement effect inside the switch housing 11.

[0043] This invention is further configured such that a display 15 is provided at the upper end of the switch housing 11, and the display 15 is connected to the control board 2. This design allows the user to observe the power supply status via the display 15, facilitating user monitoring.

The design of the snap-fit ​​grooves 113 facilitates connection with external components, thereby improving the connection strength and providing a better connection effect compared to a flat bottom surface.
