Description
Technical field
The utility model is related to membrane switch technology fields, refer specifically to a kind of magnet film switch.
Technical background
Switch variety currently on the market is various, how much is used to control electrical appliance equipment using condenser type, photoelectric switch
Break-make, but since the influence capacitance-type switch sensitivity of arrived environmental factor is low, stability is poor；Photoelectric switch is easy production
Raw security risk, environmental pollution is serious, and then magnetic switch progresses into market, and magnetism mostly uses mechanical structure greatly at present,
Patent No. CN201010532127 patent names " a kind of magnetic switch " control electrical equipment using being attracted between magnet with disconnecting
Break-make, it is simple in structure, pollution is few, but for opposite current thin film switch, this magnet contactor is bulky, is mainly used for
The break-make of household electric refrigerator intraoral illumination lamp is controlled, purposes is single, of high cost.
Invention content
For the above-mentioned deficiency of existing magnetic switch, the purpose of this utility model is to provide a kind of novel magnet films
Switch, this magnet film switch have many advantages, such as that small, purposes is wide, simple in structure, it is easy to use, can be used as desk lamp or
The mating switch of the electrical equipments such as household LED lamp, refrigerator lighting lamp.
To achieve the above object, the utility model adopts the following technical solution realizes：
A kind of magnet film switch, including magnetosphere, insulating layer and primer layer, it is characterised in that：The magnetosphere includes
Big magnetic film a and big magnetic film b, is connected with therebetween elastic insulated, close to the two of primer layer direction on the insulating layer
End is equipped with conductive sheet a and conductive sheet b, has a small magnetic film on separate primer layer direction centre position；It is two big magnetic
Magnetic force between film is more than the magnetic force between big magnetic film b and small magnetic film.
Further, the magnetosphere, insulating layer are identical with primer layer length.
Further, the big magnetic film b is made of metal material.
The utility model advantageous effect：
(1) simple in structure, practical and convenient, purposes is wide, at low cost；
(2) high sensitivity, environmental pollution are small, and strong antijamming capability is safe to use.
Description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings：
Fig. 1 is structural schematic diagram.
In figure：Elastic insulated 2- insulating layers 2.1- of the big property iron film b 1.3- of the big magnetic film a 1.2- of 1- magnetospheres 1.1-
Small magnetic film 3.1- conductive sheets a 3.2- conductive sheet b 3- primer layers
Specific embodiment
It elaborates with reference to the accompanying drawings of the specification to the utility model, in order to which those skilled in the art manage
The utility model is solved, it should be apparent that the utility model is not limited to the range of specific implementation mode, to the common of the art
For technical staff, as long as various change is in the scope of the utility model that the attached claims limit and determine, these become
Change is it will be apparent that all utilize the innovation and creation of the utility model design in the row of protection.
As shown in Figure 1, this magnet film switchs, including magnetosphere 1, insulating layer 2 and primer layer 3, it is characterised in that：It is described
Magnetosphere 1 includes big magnetic film a1.1 and big magnetic film b1.2, is connected with elastic insulated 1.3 therebetween, the insulating layer 2
The upper both ends close to 3 direction of primer layer are equipped with conductive sheet a3.1 and conductive sheet b3.2, far from 3 direction centre position of primer layer
A small magnetic film 2.1 is set；Magnetic force between two big magnetic film is more than the magnetic between big magnetic film b1.2 and small magnetic film 2.1
Power.
After pressing big 1.1 buttons of magnetic film a, big magnetic film a 1.1 is pulled together with big property iron film b1.2, big property iron
Film b1.2 is detached with small magnetic film 2.1, and electrical equipment is now in off-state；Loosen big property iron film b1.1, due to elastic exhausted
The effect magnetic film a 1.1 of embolium 1.3 is flicked with big property iron film b1.2, and big property iron film b1.2 is pull-in on small magnetic film 2.1
Together, conductive sheet a 3.1 and conductive sheet b 3.2 is linked to be a circuit by big property iron film b1.2 at this time, at this time electrical equipment
It is switched on.
