Preferably, described key body is strip, and described first magnetic force block is positioned at the lower surface of key body one end.Such structure realizes single-ended switch.
Optimal way can also be, described key body is strip, and described first magnetic force block is positioned at the middle part of key body lower surface.Such structure realizes two-terminal switch.
Optimal way can also be, described key body is polygon, and described first magnetic force block is positioned at the central authorities of key body lower surface.Such structure realizes multipoint switch.
More preferably, described key body is regular polygon, and described first magnetic force block, the second magnetic force block are the regular polygon that limit number is equal with key body limit number, and the position on the limit of the first magnetic force block, the second magnetic force block is corresponding with the position on the limit of key body.Such structure makes the every bit of multipoint switch all more consistent.
Optimal way can also be, described key body is circular, and described first magnetic force block is positioned at the central authorities of key body lower surface; Described first magnetic force block, the second magnetic force block are regular polygon.
Further technical scheme is, described first magnetic force block, the second magnetic force block are permanent magnet blocks.Such structure ensure that the adsorption capacity between the first magnetic force block and the second magnetic force block, can not mutually come off.
Further technical scheme can also be, described second magnetic force block is electromagnet, and is connected with power supply circuits.Such structure makes resilience force more easily regulate.
Magnetic suck reset switch of the present invention has following beneficial effect:
1, structure is simple.
2, the natural characteristic of magnetic material is adopted to fix, mechanical fulcrum, without wearing and tearing.
3, bounce-back dynamics and damping feel adjust by the amount of magnetizing.
4, without limiting useful life.
5, be conducive to making complete noncontacting switch, realize complete waterproof construction, can be used under water.
6, architectural characteristic, is more suitable for manufacturing very thin type switch, saves manufacturing material cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the first embodiment of the present invention.
Fig. 2 is the schematic diagram of the second embodiment of the present invention.
Fig. 3 is the key body structure schematic diagram of the third embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Figure 1 shows that the execution mode of the single-ended switch of magnetic suck reset switch of the present invention, comprise base 2 and key body 1, between base 2 and key body 1, be provided with gap; The lower surface of key body 1 is fixed with the first magnetic force block 3, and the upper surface of base 2 is provided with the second magnetic force block 4; First magnetic force block 3 and the second magnetic force block 4 at least one have magnetic force; First magnetic force block 3 adsorbs with the second magnetic force block 4 and is connected.Wherein, described key body 1 is strip, and described first magnetic force block 3 is positioned at the lower surface of key body 1 one end.When one end be not connected with the first magnetic force block 3 of key body 1, stressed when pressing, whole reset switch is in key-press status, as shown in Figure 1; Upon its release, the effect of the absorption affinity of the stressed second magnetic force block 4 of the first magnetic force block 3, makes key body 1 under the effect of lever principle, and this one end be not connected with the first magnetic force block 3 again lifting is resetted.Such mode structure is simple, adopts the natural characteristic of magnetic material to fix, mechanical fulcrum, without wearing and tearing, thus can be more suitable for making slim switch.
Figure 2 shows that the execution mode of two-terminal switch of the present invention, be with the difference of the first embodiment above-mentioned, described first magnetic force block 31 is positioned at the middle part of key body 11 lower surface, the two ends of key body 11 are made to be pressed like this, no matter which side is pressed, and can reset with the suction-operated of magnetic force.
Figure 3 shows that the execution mode of multipoint switch of the present invention, be with the difference of the first embodiment above-mentioned, key body 12 is circular, and described first magnetic force block 32 is positioned at the central authorities of key body 12 lower surface; Described first magnetic force block 32, second magnetic force block (not shown in Fig. 3) is regular polygon.Such structure makes circumferentially any one point of key body 12, as long as position is corresponding with the limit of the first magnetic force block 32, can, as a button point, be wherein positive eight shapes in the present embodiment.In addition, also key body 12 itself can be made into regular polygon, corresponding with the limit of the first magnetic force block 32, second magnetic force block.
In above-mentioned three embodiments, the first magnetic force block, the second magnetic force block not merely refer to the magnetic magnet of tool, also refer to the material that can be magnetized in magnetic field, such as iron etc.In first magnetic force block and the second magnetic force block, as long as there is one to be that the magnet with magnetic force can realize both absorption mutually, such as the first magnetic force block is iron, and the second magnetic force block is magnet, and can realize absorption like this, the use simultaneously reducing magnet reduces costs.Also can be that both are magnet, as long as to adjust direction be both is mutual adsorbed state.Such mode, due to contactless design, can be used for making complete water proof switch.The enforcement of the first magnetic force block, the second magnetic force block also can be that wherein one adopts electromagnet, be connected with power supply circuits, just there is magnetic after energising, although such mode adds installation work amount, but the size of the quantity of magnetism can be changed by the size adjusting electric current, thus change the resilience force, damping force etc. of button, more easily regulate.The mode of direct employing magnet, also can carry out the adjustment of resilience force, damping force by the amount of magnetizing.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
