Specifically, the first magnetic conductor 20 has a first end 201 and a second end 202 opposite to each other; the permanent magnet 10 contacts with the first end 201 of the first magnetizer 20, the first magnetizer 20 is provided with a magnetic through hole 21, the second magnetizer 30 contacts with the second end 202 of the first magnetizer 20, the magnetic pole direction of the permanent magnet 10 can be changed by rotating the permanent magnet 10, and the magnetic force between the first magnetizer 20 and the second magnetizer 30 is controlled.
It should be noted that, when the N pole and the S pole of the permanent magnet 10 are located as shown in fig. 1 to fig. 3, the rotary switch device 100 is in an open state, the axial direction of the permanent magnet 10 is parallel to the axial direction of the magnetic through hole 21, and magnetic lines of force are emitted from the N pole of the permanent magnet 10, because the medium in the magnetic through hole 21 is air and the magnetic conductivity of the air is smaller than that of the first magnetic conductor 20 under normal conditions, the magnetic lines of force will pass through one end of the first magnetic conductor 20 close to the permanent magnet 10, and finally the magnetic lines of force return to the S pole of the permanent magnet 10, thereby forming a complete loop. At this time, the magnetic force line does not pass through the second magnetizer 30, and therefore, there is no magnetic force between the first magnetizer 20 and the second magnetizer 30, and the first magnetizer 20 and the second magnetizer 30 can be easily separated, so that the rotary switch device 100 can be easily turned on.
When the permanent magnet 10 is rotated to the N pole and S pole positions of the permanent magnet 10 as shown in fig. 4 to 6, the rotary switch device 100 is in a closed state, the axial direction of the permanent magnet 10 is perpendicular to the axial direction of the magnetic conductive through hole 21, magnetic lines of force are emitted from the N pole of the permanent magnet 10, the magnetic lines of force move along the first magnetic conductor 20 in a direction close to the second magnetic conductor 30 and enter one side of the second magnetic conductor 30, and finally the magnetic lines of force return to the S pole of the permanent magnet 10 from the other side of the second magnetic conductor 30 to form a complete loop. At this time, the magnetic force lines pass through the first magnetizer 20 and the second magnetizer 30 simultaneously, so that a magnetic force exists between the first magnetizer 20 and the second magnetizer 30, and the first magnetizer 20 and the second magnetizer 30 are difficult to separate from each other, so that the rotary switch device 100 is kept tightly closed.
It should be added that the magnetic conductive through hole 21 may be a through hole directly formed on the first magnetic conductor 20, or a through hole formed by surrounding the groove on the first magnetic conductor 20 and the second magnetic conductor 30, and is intended to allow a medium with a magnetic conductivity smaller than that of the first magnetic conductor 20 to be contained in the magnetic conductive through hole 21.
Compared with the prior art, the rotary switch device 100 provided by the application can change the magnetic pole direction of the permanent magnet 10 by rotating the permanent magnet 10, and control the magnetic force between the first magnetizer 20 and the second magnetizer 30, so that the rotary switch device 100 can be opened easily and closed tightly when closed.

In another embodiment of the present application, referring to fig. 1 and fig. 4, the first magnetic conductor 20 has a connecting plate 22 and a pair of side plates 23, the connecting plate 22 contacts the permanent magnet 10, first ends of the pair of side plates 23 are respectively connected to two ends of the connecting plate 22, second ends of the pair of side plates 23 respectively contact the second magnetic conductor 30, and the magnetic through hole 21 is located between the pair of side plates 23. It can be understood that, the connecting plate 22 is in close contact with the permanent magnet 10, so that the magnetic field lines of the permanent magnet 10 are conveniently guided into the first magnetizer 20, the side plate 23 is in contact with the second magnetizer 30, so that the magnetic field lines guided into the first magnetizer 20 can be guided into the second magnetizer 30, and the magnetic field lines are guided back to the permanent magnet 10 again after passing through the second magnetizer 30, so that when the rotary switch device 100 is in the closed state, the magnetic field lines of the permanent magnet 10 can pass through the second magnetizer 30 and form a complete loop.
