And one end of the movable frame 11 is movably connected to one end of the first fixing portion 100 and one end of the second fixing portion 101, the other end of the movable frame 11 is provided with a permanent magnetic portion 110, the permanent magnetic portion 110 is located between the first magnetic portion 100a and the second magnetic portion 101a, and two magnetic poles of the permanent magnetic portion 110 are respectively arranged corresponding to the first magnetic portion 100a and the second magnetic portion 101 a. The movable frame 11 can move relative to the fixed frame 10 in a direction toward the first fixed portion 100 or the second fixed portion 101, so that the permanent magnet portion 110 is magnetically connected to the first magnetic portion 100a or the second magnetic portion 101 a.

Specifically, when the movable frame 11 moves relative to the fixed frame 10 along the direction toward the first fixed portion 100 until the movable frame 11 abuts against the first fixed portion 100, the permanent magnetic portion 110 abuts against and magnetically attracts the first magnetic portion 100a, so that the movable frame 11 is maintained in a state where the first fixed portion 100 abuts against, and at this time, the bistable magnetic control device 1 is in a stable state; when the movable frame 11 moves relative to the fixed frame 10 along the direction toward the second fixed portion 101 until the movable frame 11 abuts against the second fixed portion 101, the permanent magnetic portion 110 abuts against and magnetically attracts the second magnetic portion 101a, so that the movable frame 11 is kept in the state of abutting against the second fixed portion 101, and at this time, the bistable magnetic control device 1 is in another stable state.

In some embodiments, the first fixing portion 100 and one end of the second fixing portion 101 are fixedly connected by welding, gluing or thread structure, which is beneficial to keep the relative position between the first fixing portion 100 and the second fixing portion 101 stable, so as to keep the relative distance between the other end of the first fixing portion 100 and the other end of the second fixing portion 101 stable.

Optionally, the fixed frame 10 further includes a connecting portion 102, one end of the first fixing portion 100 and one end of the second fixing portion 101 are respectively connected to the connecting portion 102 by welding, gluing or thread structure, one end of the movable frame 11 is movably connected to the connecting portion 102 by a hinge structure, a sliding slot structure or other structures, and the first fixing portion 100, the second fixing portion 101 and the movable frame 11 are all connected by the connecting portion 102, so as to facilitate integration of a connection structure among components of the bistable magnetic control device 1 and simplify a structure and a manufacturing and assembling process of the bistable magnetic control device 1.

In another alternative embodiment, the first magnetic part 100a is separately provided from the other end of the first fixing part 100, and/or the second magnetic part 101a is separately provided from the other end of the second fixing part 101. Specifically, the first magnetic part 100a is disposed separately from the other end of the first fixing part 100, or the second magnetic part 101a is disposed separately from the other end of the second fixing part 101, or the first magnetic part 100a is disposed separately from the other end of the first fixing part 100, and the second magnetic part 101a is disposed separately from the other end of the second fixing part 101, which is beneficial to simplifying the manufacturing process of the fixing frame 10.

In the present embodiment, the first magnetic part 100a is provided separately from the other end of the first fixing part 100, and the second magnetic part 101a is provided separately from the other end of the second fixing part 101.

It is understood that, in order to magnetically attach the permanent magnet part 110 to the first magnetic part 100a or the second magnetic part 101a, the first magnetic part 100a and the second magnetic part 101a should be made of a material having magnetism.

In an alternative embodiment, the first magnetic part 100a and the second magnetic part 101a are metal components made of metal materials such as iron, cobalt, nickel, etc., which is beneficial to make the structure of the fixing frame 10 simple and easy to design and manufacture.

In another alternative embodiment, the first magnetic part 100a and the second magnetic part 101a may be electromagnetic components, which is beneficial to increase the magnetic force between the permanent magnetic part 110 and the first magnetic part 100a and the second magnetic part 101a, respectively, so that the magnetic connection between the permanent magnetic part 110 and the first magnetic part 100a or the second magnetic part 101a is more stable.

It is understood that when the first magnetic part 100a is different from the second magnetic part 101a, the first magnetic part 100a may be a metal component and the second magnetic part 101a may be an electromagnetic component, or the first magnetic part 100a may be an electromagnetic component and the second magnetic part 101a may be a metal component.

In some embodiments, one end of the movable frame 11 is movably connected to the first fixing portion 100 or the second fixing portion 101 through a hinge structure or a sliding slot structure, or both the first fixing portion 100 and the second fixing portion 101 are movably connected to the movable frame 11 through a hinge structure or a sliding slot structure. Specifically, as can be seen from the foregoing, one end of the movable frame 11 can be movably connected to the connecting portion 102 through a hinge structure or a sliding slot structure. It is understood that the movable frame 11 only needs to be located between the first fixing portion 100 and the second fixing portion 101 and can move away from the first fixing portion 100 to abut against the second fixing portion 101, or move away from the second fixing portion 101 to abut against the first fixing portion 100, and the position where the movable frame 11 is movably connected with the fixed frame 10 is not particularly limited in this embodiment.

In some embodiments, the movable frame 11 may be plate-shaped, cylindrical, conical, truncated, or other shapes. It is understood that the shape of the movable frame 11 only needs to be sufficient to enable the permanent magnet portion 110 to move away from the first fixing portion 100 to abut against the second fixing portion 101, or move away from the second fixing portion 101 to abut against the first fixing portion 100, and the shape of the movable frame 11 is not particularly limited in this embodiment. For example, the movable frame 11 may have a column shape, which is beneficial to make the structure of the movable frame 11 simple.

In some embodiments, the movable frame 11 may be made of one or more of plastic, metal, rubber, wood or other materials, as long as the movable frame 11 can be shaped into a designed shape, and the material of the movable frame 11 is not particularly limited in this embodiment. Preferably, the movable frames 11 are made of plastic material, which is beneficial to reduce the overall mass of the bistable magnetic control device 1.

In an alternative embodiment, the permanent magnet portion 110 is integrally formed at the other end of the movable frame 11, which is beneficial to reduce the number of parts of the movable frame 11, so that the manufacturing and assembling processes of the movable frame 11 are simple, and the possibility of losing parts in the using and assembling processes is reduced.

In another alternative embodiment, the permanent magnet portion 110 is formed separately from the other end of the movable frame 11, which is beneficial to simplifying the manufacturing process of the movable frame 11. For example, the permanent magnet portion 110 is formed separately from the other end of the movable frame 11, and the permanent magnet portion 110 may be fixedly connected to the other end of the movable frame 11 by welding, gluing, a threaded structure, a fastening structure, or other methods, which is beneficial to firmly connecting the permanent magnet portion 110 and the movable frame 11, so that the permanent magnet portion 110 is not easily detached from the movable frame 11.

Alternatively, the permanent magnet part 110 may be a permanent magnet made of one or more of iron, nickel, aluminum, chromium, cobalt, or other materials, which is beneficial to make the permanent magnet part 110 have strong and constant magnetism, thereby prolonging the service life of the bistable magnetic control device 1.

Of course, the permanent magnet part 110 has opposite N-pole regions 110a and S-pole regions 110 b. It is understood that the N-pole region 110a may be disposed opposite to the first magnetic part 100a and the S-pole region 110b may be disposed opposite to the second magnetic part 101a, or the N-pole region 110a may be disposed opposite to the second magnetic part 101a and the S-pole region 110b may be disposed opposite to the first magnetic part 100a, as long as the N-pole region 110a and the S-pole region 110b of the permanent magnetic part 110 are disposed opposite to different magnetic parts, respectively, and the disposition positions of the N-pole region 110a and the S-pole region 110b of the permanent magnetic part 110 are not particularly limited in this embodiment.

The present embodiment is described by taking an example in which the N-pole region 110a of the permanent magnet portion 110 corresponds to the first magnetic portion 100a and the S-pole region 110b can correspond to the second magnetic portion 101 a.

In some embodiments, the movable frame 11 has a state of disconnecting the currently connected magnetic portion and magnetically connecting to another magnetic portion under an external force, and the movable frame 11 has a state of maintaining the magnetically connecting to the another magnetic portion when the external force is removed. The currently connected magnetic part is the first magnetic part 100a or the second magnetic part 101 a. That is, the bistable magnetic control device 1 acts on the movable frame 11 by an external force, so that the movable frame 11 is separated from the currently connected first magnetic part 100a and moves to be magnetically attracted to the second magnetic part 101a, or is separated from the currently connected second magnetic part 101a and moves to be magnetically attracted to the first magnetic part 100 a.

It can be understood that the external force may be a magnetic force generated by the magnetic component approaching the permanent magnetic portion 110 and attracting or repelling the permanent magnetic portion 110, or the external force may be a force generated by a human hand or other structure contacting the permanent magnetic portion 110 and applied to the permanent magnetic portion 110, as long as the external force can act on the movable frame 11 and cause the permanent magnetic portion 110 to disconnect the currently connected magnetic portion and magnetically connect to another magnetic portion, and the type of the external force and the manner of acting on the movable frame 11 are not specifically limited in this embodiment.

For example, the external force is that a magnetic component such as a permanent magnet or an electromagnet is close to the permanent magnet part 110, and by using the principle that like poles repel and unlike poles attract, an attractive or repulsive magnetic force is generated to the permanent magnet part 110, so that the permanent magnet part 110 is separated from the currently connected magnetic part by an attractive force and is attracted to the magnetically attracted and connected to another magnetic part, or is separated from the currently connected magnetic part by a repulsive force and is repelled to the magnetically attracted and connected to another magnetic part, which is beneficial to enabling the structure applying the external force to the permanent magnet part 110 not to contact with the bistable magnetic control device 1, so that the bistable magnetic control device 1 can be controlled to switch between two different stable states.

The following is a brief description of the steady-state maintaining and bistable switching principle of the bistable magnetic control device 1 of the present embodiment:

in the bistable magnetic control device 1 disclosed in this embodiment, the fixed frame 10 having the first magnetic part 100a and the second magnetic part 101a and the movable frame 11 having the permanent magnetic part 110 are provided, and the permanent magnetic part 110 is located between the first magnetic part 100a and the second magnetic part 101a, and the magnetic attraction force generated between the permanent magnetic part 110 and the first magnetic part 100a or between the permanent magnetic part 110 and the second magnetic part 101a is utilized to make the permanent magnetic part 110 magnetically attract the first magnetic part 100a when contacting the first magnetic part 100a or attract the second magnetic part 101a when contacting the second magnetic part 101a, so that the movable frame 11 is stably maintained in a state of contacting the first fixed part 100 or the second fixed part 101.

When the permanent magnet portion 110 needs to be disconnected from the currently connected magnetic portion and magnetically connected to another magnetic portion, only an external force needs to be applied to the movable frame 11 to disconnect the currently connected magnetic portion from the movable frame 11 and move to the magnetically connected magnetic portion. The external force may be a magnetic force applied to the permanent magnet part 110 by a magnetic field when the magnetic part approaches the permanent magnet part 110, or a force applied to the permanent magnet part 110 by a human hand or other structure contacting the permanent magnet part 110.

Example two

Referring to fig. 3 and fig. 4, a second embodiment of the present invention discloses a switch system 2, which includes a circuit switch 20, a transmission component 21, and the bistable magnetic control device 1 according to the first embodiment. The circuit switch 20 is disposed at one side of the first fixing portion 100, and one end of the transmission member 21 is connected to the movable frame 11. The transmission component 21 is used to turn on or off the circuit switch 20 when the permanent magnet portion 110 is magnetically connected to the first magnetic portion 100a, or when the permanent magnet portion 110 is magnetically connected to the second magnetic portion 101 a. Specifically, when the permanent magnet portion 110 is magnetically connected to the first magnetic portion 100a, the transmission member 21 turns on or off the circuit switch 20, or when the permanent magnet portion 110 is magnetically connected to the second magnetic portion 101a, the transmission member 21 turns on or off the circuit switch 20, so as to control the bistable magnetic control device 1 to switch between two stable states or maintain one of the stable states, thereby controlling the circuit switch 20 to switch between on and off, or maintain the on or off state. Because the bistable magnetic control device 1 only needs external force to act on the bistable magnetic control device 1 when the bistable magnetic control device 1 is switched from one stable state to another stable state, the on and off of the circuit switch 20 is controlled by the bistable magnetic control device 1, electric energy or other energy for controlling the bistable magnetic control device 1 to be switched between the two stable states can be effectively saved, and thus, the switching system is energy-saving and environment-friendly.

In the present embodiment, the transmission member 21 turns on the circuit switch 20 when the permanent magnet portion 110 is magnetically connected to the first magnetic portion 100a, and the transmission member 21 turns off the circuit switch 20 when the permanent magnet portion 110 is magnetically connected to the second magnetic portion 101 a.

Referring to fig. 4, in an alternative embodiment, the circuit switch 20 is a resilient switch, which is advantageous to maintain the initial state of the circuit switch 20 when the circuit switch is not subjected to an external force. Illustratively, the initial state of the circuit switch 20 when not subjected to the external force is an off state, and the circuit switch 20 when subjected to the external force is an on state.

Optionally, the circuit switch 20 has an elastic structure 200c, a first switch portion 200a and a second switch portion 200b, when the first switch portion 200a abuts against the second switch portion 200b, the circuit switch 20 is turned on, and when the first switch portion 200a is separated from the second switch portion 200b, the circuit switch 20 is turned off. The elastic structure 200c is used to maintain the first switch unit 200a and the second switch unit 200b in a separated position state when the circuit switch 20 is not subjected to an external force.

It is understood that the first and second switching portions 200a and 200b may be made of a material having a relatively high conductivity, such as iron, copper, or silver, so that the conductivity of the first and second switching portions 200a and 200b can be ensured. Illustratively, the first switch portion 200a and the second switch portion 200b are respectively one end of two copper sheets, one end of the two copper sheets is disposed at an interval, the other end of the two copper sheets is an elastic structure 200c, and the other ends of the two copper sheets are fixed on an insulating base 202 at an interval. When the circuit switch 20 is not acted by external force, one ends of the two copper sheets are separated at intervals, so that the circuit switch 20 is disconnected, and when any one of the two copper sheets is acted by external force, one ends of the two copper sheets are abutted, so that the circuit switch 20 is closed and conducted.

Alternatively, the other end of the transmission member 21 is configured to abut against the circuit switch 20 to turn on the circuit switch 20 when the permanent magnet portion 110 is magnetically attached to the first magnetic portion 100a, or the other end of the transmission member 21 is configured to turn off the circuit switch 20 when the permanent magnet portion 110 is magnetically attached to the second magnetic portion 101 a. That is, when the permanent magnet portion 110 is magnetically connected to the first magnetic portion 100a, the transmission member 21 may contact the first switch portion 200a or the second switch portion 200b, so that the first switch portion 200a contacts the second switch portion 200b, and the circuit switch 20 is turned on. When the permanent magnet part 110 is magnetically connected to the second magnetic part 101a, the transmission member 21 is disconnected from the first switch part 200a or the second switch part 200b, and the first switch part 200a and the second switch part 200b are restored to the separated state of the initial state, so that the circuit switch 20 is turned off.

Alternatively, the transmission member 21 may be an insulating member, which is advantageous for reducing the influence on the circuit when contacting the conducting circuit switch 20.

Alternatively, the transmission member 21 may be a plastic ram, which is advantageous for reducing the overall mass of the switching system 2. Specifically, one end of the plastic ejector rod is fixedly connected to the movable frame 11 through a threaded structure, a buckle, welding or other methods, and the other end of the plastic ejector rod points to the circuit switch 20. When the permanent magnet portion 110 is magnetically connected to the first magnetic portion 100a, the plastic rod abuts against the first switch portion 200a or the second switch portion 200b, and applies an effective force to the first switch portion 200a or the second switch portion 200b, so that the first switch portion 200a abuts against the second switch portion 200b, and the circuit switch 20 is turned on. When the permanent magnet part 110 is magnetically connected to the second magnetic part 101a, the plastic plunger is disconnected from the first switch part 200a or the second switch part 200b, so that the first switch part 200a and the second switch part 200b are restored to the initial separated state, and the circuit switch 20 is turned off.

Referring to fig. 5 and fig. 6, in another alternative embodiment, the circuit switch 20 has a stationary portion 201a and a movable portion 201b, the stationary portion 201a and the movable portion 201b may be both copper sheets, iron sheets or conductive sheets made of other materials, so as to ensure the electrical conductivity of the stationary portion 201a and the movable portion 201b, one end of the stationary portion 201a is fixed on the insulating base 202, and one end of the movable portion 201b and one end of the stationary portion 201a are connected to the insulating base 202 at intervals. When the movable portion 201b moves until the other end of the movable portion 201b abuts against the other end of the stationary portion 201a, the circuit switch 20 is turned on, and when the movable portion 201b moves until the other end of the movable portion 201b is separated from the other end of the stationary portion 201a, the circuit switch 20 is turned off. In this way, only the position of the movable portion 201b is controlled, and the movable portion 201b is moved to be closed with the stationary portion 201a to turn on the circuit switch 20, or the movable portion 201b is moved to be separated from the stationary portion 201a to turn off the circuit switch 20, thereby facilitating the control.

Alternatively, the other end of the transmission component 21 is connected to the movable portion 201b, so that the other end of the transmission component 21 can be used to drive the movable portion 201b to move into abutment with the stationary portion 201a to turn on the circuit switch 20 when the permanent magnet portion 110 is magnetically connected to the first magnetic portion 100 a. And the other end of the transmission component 21 is used for driving the movable part 201b to move to be separated from the static part 201a to disconnect the circuit switch 20 when the permanent magnet part 110 is magnetically connected to the second magnetic part 101 a.

Alternatively, the transmission member may be a plastic rod, which is advantageous for reducing the overall mass of the switching system 2, and by making the transmission member 21 an insulating object, which is advantageous for reducing the influence on the circuit when contacting the conducting circuit switch 20.

Further, one end of the plastic rod is rotatably connected to the movable frame 11, and the other end of the plastic rod is rotatably connected to the movable portion 201 b. Specifically, when the permanent magnet portion 110 is magnetically connected to the first magnetic portion 100a, the movable frame 11 drives one end of the plastic rod to move to be close to the first fixing portion 100, so that the other end of the plastic rod drives the movable portion 201b to move to abut against the stationary portion 201a, and the circuit switch 20 is turned on. And when the permanent magnet part 110 is magnetically connected to the second magnetic part 101a, the movable frame 11 drives one end of the plastic rod to move to be close to the second fixed part 101, so that the other end of the plastic rod drives the movable part 201b to move to be separated from the stationary part 201a, and the circuit switch 20 is turned off.

It can be understood that an external force may act on the movable frame 11 to cause the movable frame 11 to disconnect the currently connected magnetic portion and magnetically connect to another magnetic portion, thereby controlling the on/off of the circuit switch 20. Specifically, the external force acts on the movable frame 11 to disconnect the movable frame 11 from the first magnetic portion 100a and magnetically attract and connect the movable frame 11 to the second magnetic portion 101a, so as to drive the transmission member 21 to move and disconnect the circuit switch 20, or disconnect the movable frame 11 from the second magnetic portion 101a and magnetically attract and connect the movable frame 11 to the first magnetic portion 100a, so as to drive the transmission member 21 to move and connect the circuit switch 20.

The external force may be a magnetic force generated by the magnetic component approaching the permanent magnet part 110 and attracting or repelling the permanent magnet part 110, or the external force may be a force applied by a human hand or other structure contacting the permanent magnet part 110 and applying to the permanent magnet part 110.

In some embodiments, the switch system 2 further includes a magnetic structure 22, the magnetic structure 22 is disposed on one side of the second fixing portion 101, and the magnetic structure 22 is configured to generate a magnetic field to provide an acting force for the movable frame 11 to rotate relative to the fixed frame 10, so as to control the movable frame 11 to disconnect a currently connected magnetic portion and magnetically connect to another magnetic portion through a magnetic force generated by the magnetic structure 22 in a state of not directly contacting with the movable frame 11, thereby implementing a non-contact control on the circuit switch 20. It is understood that the magnetic structure 22 can be disposed on one side of the first fixing portion 100.

In an alternative embodiment, the magnetic structure 22 is an electromagnet, so that one end of the magnetic structure 22 close to the bistable magnetic control device 1 can be controlled by a circuit to generate magnetic fields with different polarities, so as to apply an attractive force to the permanent magnet part 110, so that the permanent magnet part 110 is disconnected from the first fixing part 100 and is magnetically attracted to the second fixing part 101, or apply a repulsive force to the permanent magnet part 110, so that the permanent magnet part 110 is disconnected from the second fixing part 101 and is magnetically attracted to the first fixing part 100, so that the circuit switch 20 can be controlled by the circuit, so that the circuit switch 20 is easy to control, and further, the circuit connected by the magnetic structure can be controlled remotely to control the disconnection or connection of the circuit switch 20.

In addition, only when the control circuit switch 20 is required to be switched between the on state and the off state, the magnetic structure 22 is required to be switched on so that the magnetic structure 22 generates magnetic fields with different polarities at one end close to the bistable magnetic control device 1 to apply a magnetic force to the permanent magnet portion 110. When the circuit switch 20 is kept in the on state or the off state, due to the action of the bistable magnetic control device 1, the magnetic structure 22 does not need to be switched on, so that the power can be effectively saved, and the magnetic structure 22 can be prevented from affecting other elements in the switch circuit.

Optionally, the electromagnet has a core 220 and an electromagnetic coil 221, the electromagnetic coil 221 is sleeved on the periphery of the core 220, when the electromagnetic coil 221 is energized, two magnetic fields with different polarities are respectively formed at two ends of the core 220, so as to control the circuit switch 20 to be turned on or off by controlling the permanent magnet part 110 to be magnetically connected to the first magnetic part 100a or the second magnetic part 101 a.

Referring to fig. 4 to 6, in some alternative embodiments, two electromagnetic coils 221 are provided, two electromagnetic coils 221 are spirally wound around the outer periphery of the core 220, and the winding directions of the two electromagnetic coils on the outer periphery of the core are different, for example, one of the electromagnetic coils is wound in the clockwise direction of the core, and the other electromagnetic coil is wound in the counterclockwise direction of the core. By applying current in the same direction to any one of the electromagnetic coils 221, the electromagnet is directed to one end of the bistable magnetic control device 1 to generate magnetic fields with different polarities, which is beneficial to controlling the on/off of the circuit switch 20 by using direct current.

Referring to fig. 7 and 8, in other alternative embodiments, the electromagnetic coil 221 may be spirally sleeved around the periphery of the core 220 along one direction, and the electromagnetic coil 221 is energized with currents in different directions to make the electromagnet point to one end of the bistable magnetic control device 1 to generate magnetic fields with different polarities, which is beneficial to make the electromagnet simple in structure.

Referring to fig. 9 and fig. 10 together, in another alternative embodiment, the magnetic structure 22 may be a permanent magnet, and the magnetic structure 22 has an N pole end 222a and an S pole end 222b, which are beneficial to forming a magnetic field force acting on the permanent magnet part 110 through a permanent magnetic field of the magnetic structure in a non-energized state, so as to assist in enhancing the magnetic attraction connection strength between the permanent magnet part 110 and the currently connected magnetic part.

Further, the magnetic structure 22 has a driving component 223, the driving component 223 is configured to drive the magnetic structure 22 to move, so that the magnetic structure 22 approaches the bistable magnetic control device 1 with different polarity ends, thereby applying an attractive force to the permanent magnet portion 110, and disconnecting the permanent magnet portion 110 from the first fixing portion 100 and magnetically connecting the permanent magnet portion 110 to the second fixing portion 101, or applying a repulsive force to the permanent magnet portion 110, and disconnecting the permanent magnet portion 110 from the second fixing portion 101 and magnetically connecting the permanent magnet portion 110 to the first fixing portion 100.

Illustratively, the magnetic structure 22 is a bar-shaped permanent magnet, and the driving member 223 is a rotating electrical machine, which is beneficial to make the structure of the magnetic structure 22 simple. Specifically, the rotating electrical machine is connected to the middle of the magnetic structure 22 in the length direction, and the rotating electrical machine is used for controlling two different polarity ends of the magnetic structure 22 to rotate around the middle of the magnetic structure 22, so that the magnetic structure 22 can be respectively close to the bistable magnetic control device 1 through the different polarity ends, and therefore the circuit switch 20 is controlled to be turned on and off, and the control is easier and more convenient.

In the switching system 2 disclosed in this embodiment, the bistable magnetic control device 1 and the transmission member 21 provided on the movable frame 11 are used to control the circuit switch 20 to be maintained in the on or off state by using the transmission member 21 by making the transmission member 21 obtain different stable positions in a state where the movable frame 11 is magnetically attracted to one magnetic portion. Alternatively, the transmission member 21 can be switched between two stable positions by disconnecting the currently connected magnetic part under the action of an effective magnetic force or a contact-type acting force by using the movable frame 11 and moving to a state of magnetically attracting the other magnetic part, so that the transmission member 21 is used to control the circuit switch 20 to switch between the on state and the off state. Because the bistable magnetic control device 1 only needs external force to act on the bistable magnetic control device 1 when the bistable magnetic control device 1 is switched from one stable state to another stable state, the on and off of the circuit switch 20 is controlled by the bistable magnetic control device 1, electric energy or other energy for controlling the bistable magnetic control device 1 to be switched between the two stable states can be effectively saved, and thus, the switching system is energy-saving and environment-friendly.

The bistable magnetic control device and the switch system disclosed in the embodiments of the present invention are described in detail above, and the principle and the implementation of the present invention are explained herein by using specific examples, and the description of the above embodiments is only used to help understanding the bistable magnetic control device and the switch system of the present invention and the core idea thereof; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, and in summary, the content of the present specification should not be understood as the limitation of the present invention.
