At the same time, the slider 3 triggers the micro switch 6 to switch the state so that the dual power switch is switched to the manual mode. At this time, the padlock hole 51 of the lock plate 5 can extend from the lock plate hole 12 of the housing and the lock plate 5 limits the slider 3, so that the slider 3 remains in the padlock position and cannot be moved to the automatic position and the manual position. The padlock 7 is inserted into the padlock hole 51 to lock the lock plate 5, so that the slider 3 remains in the padlock position to avoid misoperation during equipment maintenance. In addition to the padlock 7, other locking tools can also be used to lock the lock plate 5 in cooperation with the padlock hole 51. The padlock structure of the dual power switching switch of the present embodiment cooperates with the baffle 4, the locking plate 5 and the micro switch 6 through the slider 3 arranged for linear movement, so as to realize the dual power cutting and padlocking of the dual power switching switch, thereby playing a role in protecting the safety of electricity use. At the same time, the slider 3 which moves linearly drives the baffle 4 to rotate in an articulated manner, so that the baffle 4 does not need to be additionally provided with a reset structure, the structure is simplified, the action relationship is simple and reliable, and the reliability of the padlock function is improved. The baffle 4 is arranged to rotate, and occupies less space.

[0034] like Figure 1 and Figure 4As shown, the slider 3 moves linearly through the automatic position, the manual position and the padlock position in sequence, and the top surface of the upper cover 1 is provided with indication marks corresponding to the dial button 2 in rows and in sequence for indicating the automatic position, the manual position and the padlock position, such as "automatic", "manual", "padlock" and other text marks, or other symbols, colors, patterns, etc., or a combination of symbols, colors, patterns, etc. The dial button 2 is turned to make the slider 3 move linearly to the automatic position, the slider 3 drives the baffle 4 to block the manual operation hole 11, and the slider 3 triggers the micro switch 6 to switch the state so that the dual power switch is switched to the automatic mode, and at this time, the slider 3 limit lock piece 5 moves so that the padlock hole 51 is located in the housing; the dial button 2 is turned to make the slider 3 move linearly to the manual position, the slider 3 drives the baffle 4 until the baffle 4 avoids the manual operation hole 11, and the slider 3 triggers the micro switch 6 to switch the state so that the dual power switch is switched to the manual mode, and the dual power switch is turned on or off by operating the manual operation shaft, and the slider 3 limit lock piece 5 moves so that the padlock hole 51 is located in the housing.
