In this way, the linkage mechanism 30 and the output terminal 60 do not need to be provided with a modular shell, and the fixed shell 10 is directly used for protection, thereby saving the overall volume size. The linkage mechanism 30 is actuated under the action of the metal component 50 and the magnetic component 40 in the first cavity 12, wherein the metal component 50 and the magnetic component 40 are located on different door leaves. When the door leaf is closed, the metal component 50 and the magnetic component 40 are close to and magnetically fixed, and at the same time, the metal component 50 is in contact with and connected to the linkage mechanism 30; or when the door leaf is closed, the metal component 50 and the magnetic component 40 are away from each other, and at the same time, the metal component 50 is disconnected from the linkage mechanism 30, so that different output terminals 60 are electrically connected to realize the on-off of the external circuit; since the fixed shell 10 includes two half shells 11 that can be detachably connected, if the first cavity 12 and the third cavity 12 are connected, the metal component 50 and the magnetic component 40 are connected to each other, and the metal component 50 is disconnected from the linkage mechanism 30, the output terminals 60 are electrically connected to realize the on-off of the external circuit; Dust enters the second cavity 13 and the plurality of third cavities 14, which can be cleaned by disassembling the half shell 11, so that it is convenient to clean the internal linkage mechanism 30 and the output terminal 60; in addition, a protective cover 20 is provided on one side of the output terminal 60 of the fixed shell 10, and a wire hole 21 is provided on the protective cover 20 to avoid affecting the wiring setting.

[0032] In an optional solution of the present embodiment, more preferably, the number of the third cavity 14 and the number of the output terminals 60 are both set to four, and the linkage mechanism 30 is connected to two output terminals 60 at a time.

[0033] For further information, see Figure 2One end of each output terminal 60 is electrically connected to a contact bridge 61, and the other end of the contact bridge 61 extends into the second cavity 13 and is used to be electrically connected to the linkage mechanism 30; correspondingly, the number of the contact bridges 61 is the same as the number of the output terminals 60, and the contact bridge 61 can be embedded between adjacent baffles 15, with one end placed in the third cavity 14 to be connected to the output terminal 60, and the other end placed in the second cavity 13 to be able to be connected to the linkage mechanism 30.

[0034] Specifically, the specific structure of the linkage mechanism 30 adopts the mechanical linkage structure of a conventional spring-type micro switch, mainly including a linkage rod 31 and contacts 32 arranged on both sides of the linkage rod 31. The contacts 32 on both sides can move synchronously with the linkage rod 31. Two output terminals 60 and contact bridges 61 are respectively arranged on both sides of the linkage rod 31, and the contact 32 on one side is arranged between the ends of the two contact bridges 61 on the same side along the movement direction of the linkage rod 31. In this way, the movement of the linkage rod 31 can drive the contacts 32 on both sides to move synchronously, so that the contacts 32 on both sides are in contact with two different contacts. The bridge 61 is connected, thereby controlling the on-off of the external circuit; in addition, one end of the linkage rod 31 passes through the first cavity 11 and extends out of the fixed shell 10 and approaches the metal component 50, and one end of the linkage rod 31 is connected to the inner wall of the fixed shell 10 through the reset spring 33; when the door is closed, the metal component 50 contacts the linkage rod 31 and squeezes the linkage rod 31 and the reset spring 33, so that the contact 32 is connected to different contact bridges 61; when the door is opened, the metal component 50 is disengaged from the linkage rod 31, and the linkage rod 31 is connected to different contact bridges 61 under the restoring force of the reset spring 33.

[0035] Furthermore, the metal component 50 is configured as an inductive metal sheet and is disposed on the side of the magnetic component 40 facing away from the fixed shell 10; during the use of the door magnetic switch 100 provided in this embodiment, the metal component 50 and other structures are located on different door leaves. If it is applied to a door leaf made of metal material, the metal component 50 does not need to be set, and the magnetic component 30 can be directly magnetically attracted to the metal door leaf. If it is applied to a wooden door leaf, the metal component 50 needs to be set on the door leaf to cooperate with the magnetic component 30.

[0036] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
