Abstract
The utility model discloses a micro switch which comprises a shell (1), a moving part (2) and wiring terminals (3), wherein the top wall of the shell (1) is provided with a positioning hole (1.1); the moving part (2) is provided with a bulge (2.1); the moving part (2) can be upwards and downwards movably arranged in the shell (1), and the bulge (2.1) penetrates through the positioning hole (1.1) and is exposed outside of the shell (1); the number of the wiring terminal (3) is two, and the two wiring terminals (3) are both arranged on the bottom wall of the shell (1) and located below the moving part (2); and the micro switch is characterized in that the moving part (2) is a conductive magnet, and the top wall of the shell (1) is provided with a metal sheet (4) which can attract a magnet. The micro switch is high in cost, small in volume, good in reliability, and long in service life, and can not be affected by temperature.
Description
Technical field
The utility model relates to a kind of electrical accessorie, relates in particular to a kind of sensitive switch.
Background technology
Sensitive switch is a kind of application electrical accessorie comparatively widely, like the button on computer mouse button, mobile phone input button, the household electrical appliances control panel etc.The elastic structure of the sensitive switch of prior art has following several kinds of modes: spring, metal clips, plastic cement shell fragment etc.The spring sensitive switch utilizes the bounce of spring to realize switching function, and its shortcoming is that cost is high; Volume is bigger; Receive the limitation (spring can reduce along with compression number gradually) in shell fragment life-span, the useful life of this type of button, stroke, feel all can reduce along with using gradually; Shell fragment fatiguability and damaging.The metal clips sensitive switch utilizes the bounce of metal clips to realize switching function, and its shortcoming is metal material purity and material to be selected to require very high, and like silver strip etc., cost is higher; It is bigger influenced by external force, and shell fragment is prone to break after reaching final period in life-span, loss of function; Receive the limitation (elastic force of shell fragment can reduce along with compression number gradually) in shell fragment life-span, the useful life of this type of button, stroke, feel all can reduce along with using gradually.Plastic cement shell fragment sensitive switch is to be hot pressed into circular plastic rubber material or square salient point, and the bounce through this salient point realizes switching function, and its shortcoming is the operation effort, and feel is bad; Hot-forming salient point is prone to temperature influence, and subsiding appears in the easy stress that recovers of salient point during high temperature, is prone to embrittlement during low temperature; Receive the limitation (elastic force of shell fragment can reduce along with compression number gradually) of shell fragment material, the useful life of this type of button, stroke, feel all can reduce along with using gradually.
The utility model content
The technical problem that the utility model will solve is, provides that a kind of cost is high, volume is little, good reliability, long service life, the sensitive switch of temperature influence not.
The technical solution of the utility model is, a kind of sensitive switch with following structure is provided, and comprises that roof is provided with the housing of location hole, movable part and terminals; Described movable part is provided with convexity; Described movable part can be installed in the housing up or down and the described protruding location hole dew that connects is put outside shell; Described terminals are two, and two terminals all are located at the diapire of described housing and are positioned at the below of described movable part, and described movable part is a conductive magnet, and the roof of described housing is provided with the sheet metal that can attract magnet.
After adopting above structure, the utility model sensitive switch compared with prior art has the following advantages:
Because the movable part of the sensitive switch of the utility model is a conductive magnet, the roof of described housing is provided with the sheet metal that can attract magnet, therefore; As long as press the convexity on the movable part downwards with hand; Conductive magnet will contact with terminals, and terminals are connected with circuit, thereby can turning circuit; Unclamp after the hand, receive the effect of sheet metal, conductive magnetism cognition is attracted up by sheet metal, separate with terminals, thus open circuit; The sensitive switch cost of this kind structure is lower; Volume is less; Reliability is higher; The elasticity life-span is long, and elasticity can not reduce along with increasing of compression number gradually, and protruding use is minimum to useful life, stroke, the feel influence of sensitive switch; Also do not receive Influence of Temperature.
As a kind of improvement of the utility model, described sheet metal is embedded in the roof of described housing.After adopting this kind structure, can reduce volume.
Improve as the another kind of the utility model, described sheet metal be annular, be centered around described location hole around.After adopting this kind structure, sheet metal is even to the attraction of conductive magnet, makes conductive magnet stressed evenly.
Description of drawings
Accompanying drawing is the structural representation of the utility model sensitive switch.
Shown in the figure: 1, housing, 1.1, location hole, 2, movable part, 2.1, convexity, 3, terminals, 4, sheet metal.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
See also shown in the accompanying drawing, the sensitive switch of the utility model comprises that roof is provided with the housing 1 of location hole 1.1, movable part 2 and terminals 3.It is protruding 2.1 that described movable part 2 is provided with, and in this specific embodiment, described protruding 2.1 are positioned at the middle part of the upper surface of described movable part 2, with its accordingly, described location hole 1.1 is positioned at the middle part of the roof of described housing 1.Described movable part 2 can be installed in the housing 1 up or down and described protruding 2.1 perforation location holes, 1.1 dew are put outside housing 1.Described terminals 3 are two, the below that these two terminals 3 all are located at the diapire of described housing 1 and are positioned at described movable part 2, and like this, movable part 2 moves down and can contact with two terminals 3.Described movable part 2 is a conductive magnet, and in this specific embodiment, described movable part 2 is one-body molded with protruding 2.1.The roof of described housing 1 is provided with the sheet metal 4 that can attract magnet, and described sheet metal 4 is embedded in the roof of described housing 1, described sheet metal 4 be the annular, be centered around described location hole 1.1 around.
During use, as long as press the convexity 2.1 on the movable part 2 downwards with hand, conductive magnet will contact with two terminals 3, and terminals 3 respectively with circuit in two wiring points be connected, thereby can turning circuit; After unclamping hand, receive the effect of sheet metal 4, conductive magnetism is known from experience by sheet metal 4 attractions, separates with two terminals 3, thus open circuit.
