The first switch 3 is located on one side of the interlocking mechanism 4 and is connected to the interlocking mechanism 4 via the fixing member 2. The second switch 5 is located on the side of the interlocking mechanism 4 opposite to the first switch 3 and is connected to the interlocking mechanism 4 via the fixing member 2. The connecting member 6 is located on one side of the first switch 3 and the second switch 5 and is connected to both the first switch 3 and the second switch 5. After the switch is energized, the connecting member 6 can transmit signals to the PCBA board and also assist the fixing member 2 in fixing the first switch 3 and the second switch 5. The first switch 3 and the second switch 5 are connected to the interlocking mechanism 4 via the fixing member 2, and the interlocking mechanism 4 is connected to the mounting plate 1, thereby realizing the connection between the first switch 3 and the second switch 5 and the mounting plate 1. This connection method has a simple structure, is firmly installed, and will not cause slippage.

[0030] Furthermore, in some embodiments, the first switch 3 is provided with a second through hole 31, which is located on the side of the first switch 3 perpendicular to the interlocking mechanism 4, distributed at the four corners of the first switch 3, and penetrating the first switch 3.

The fixing member 2 passes through the second through hole 31 and connects to the hole 41, thereby connecting the first switch 3 to the interlocking mechanism 4.

[0031] Furthermore, in some embodiments, the second switch 5 is provided with a third through hole 51. The third through hole 51 is located on the side of the second switch 5 perpendicular to the interlocking mechanism 4, distributed at the four corners of the second switch 5, and passes through the second switch 5. The interlocking mechanism 4 is also provided with holes 41 on the side near the second switch 5, and the position and number of holes 41 match the position and number of the third through holes 51. The fixing member 2 passes through the third through hole 51 and connects with the hole 41, so that the second switch 5 is connected to the interlocking mechanism 4.

[0032] Optionally, one end of the fastener 2 is provided with a thread, and the hole 41 is also provided with a thread. The size and direction of the thread of the fastener 2 are the same as the size and direction of the thread of the hole 41.

[0033] Furthermore, in some embodiments, the mounting plate 1 is provided with a first through hole 11, and the interlocking mechanism 4 is provided with threaded holes on the side near the mounting plate 1. The threaded holes are distributed at the edge of the interlocking mechanism 4 to prevent interference with the use of the interlocking mechanism 4. The number and position of the first through hole 11 are adapted according to the number and position of the threaded holes. The interlocking mechanism 4 and the mounting plate 1 are connected by screws, which facilitates the installation and removal of the dual power switch.

[0034] Furthermore, in some embodiments, the connector 6 includes a connecting piece 61, a cover plate 62, and a third hole 63. The connecting piece 61 is used to transmit signals to the PCBA board after the switch is energized. The cover plate 62 is located on one side of the connecting piece 61, and the third hole 63 is located on the cover plate 62 and penetrates through it. The connecting piece 61 covers the top of the first switch 3 and the second switch 5. Screws pass through the third hole 63 to connect the cover plate 62 and the connecting piece 61 to the first switch 3 and the second switch 5. The auxiliary fixing member 2 fixes the first switch 3 and the second switch 5, making the connection between the first switch 3 and the second switch 5 and the interlocking mechanism 4 more secure.

[0035] Furthermore, this utility model also provides a power supply device, which includes the aforementioned dual power switch. The dual power switch is installed within the power supply device, and when the power supply device malfunctions or experiences a power outage, the dual power switch switches the power supply to the backup power supply to ensure normal power supply. The first switch 3 and the second switch 5 of the dual power switch are connected to the interlocking mechanism 4 via a fixing member 2, making the connection more secure and reliable, preventing slippage and thus ensuring the stability and reliability of the power system.

[0036] The working principle of this utility model is as follows: The interlocking mechanism 4 is connected to the mounting plate 1 via screws. The fixing member 2 passes through the second through hole 31 and the third through hole 51 and then connects to the hole 41, thereby connecting the first switch 3 and the second switch 5 to the interlocking mechanism 4. This, in turn, connects the first switch 3 and the second switch 5 to the mounting plate 1. The first switch 3 and the second switch 5 do not require additional structures to connect to the mounting plate 1, reducing production costs. This connection method is simple in structure, securely installed, and will not slip off. Furthermore, the fixing member 2 and the hole 41, and the interlocking mechanism 4 and the mounting plate 1, are all connected by threads, ensuring not only a secure and reliable connection but also easy disassembly and installation, reducing the labor intensity of workers.
