Abstract
The utility model relates to a pressing type conductive mud switch comprising a flexible and telescopic casing, wherein the casing is provided with two chambers, conductive mud is filled into the chambers, and a conducting wire is connected on the conductive mud in both ends of the casing. The utility model has simple structure, novel appearance and convenient operation and can regulate the magnitude of current.
Description
Technical field
The utility model relates to a kind of electric switch, relates in particular to a kind of squash type conduction mud switch that can regulate size of current.
Background technology
At present, what the switch of most electronic product had can regulate size of current, and what have only has an on-off function.The switch that possesses scalable size of current function all is to adopt button or knob now, but this class switch electrical structure is all very complicated, and outward appearance is poor, uses inconvenience.
Summary of the invention
The purpose of this utility model is to address the above problem and provide a kind of simple in structure, outward appearance novelty, easy to operate, as to regulate size of current squash type conduction mud switch.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
It comprises soft telescopic shell, and shell has two chambers, is filled with conduction mud in the chamber, is connected with lead on the conduction mud in the shell two ends.
Also be provided with return wire in the above-mentioned shell, the return wire outside is provided with insulating barrier.
Compared with prior art, the utility model has been obtained following technique effect:
1, the utility model is simple in structure, and is easy to process and cost is low, be easy to produce in enormous quantities, and the current control mode uniqueness, rich interesting, the outward appearance novelty, easy to use, be suitable for the Current Regulation of earphone, desk lamp etc.;
2, the return wire that is surrounded by insulating barrier runs through in the enclosure, has further strengthened the outward appearance sight of switch.
Description of drawings
Fig. 1 is the utility model cutaway view.
Wherein: 1-lead, 2-return wire, 3-shell, 4-conduct electricity mud.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of squash type conduction mud switch, it comprises soft telescopic shell 3, shell has two circular chamber, is filled with conduction mud 4 in the chamber, is connected with lead 1 on the conduction mud in the shell two ends.Can also be provided with return wire 2 in the shell, the return wire outside is provided with insulating barrier.
Conduction mud has outside certain conductivity, also has good mobility.Outer casing thickness is less, and rigidity is lower, and shape will change with one on the conduction mud so will be close to.The return wire that includes insulating barrier passes conduction mud, and its external insulation and inner lead are all used very soft and are rich in flexible material and make.Therefore can stretch crooked arbitrarily and preferably.
Operation principle of the present utility model is: this switch is because of having used above structure, so its shape can change arbitrarily, in change procedure, the volume of the conduction mud in two chambers of switch will change.Along with the volume of the conduction mud in the chamber increases and reduces, the resistance of conduction mud also changes thereupon in this chamber.When pushing the switch right half, conduction mud flows into left chamber by right chamber, causes the volume of the conduction mud in the left chamber to increase, and when extruding switch left half, conduction mud flows into right chamber by left chamber, and the mud volume that causes conducting electricity in the left chamber reduces.Along with conduction mud volume in the left chamber changes, its resistance sizes also changes (conductor resistance is disregarded) thereupon.According to Ohm's law I=U/R, size of current also changes thereupon.And its resistance sizes just equals the resistance sizes of switch.So the resistance of switch changes, thereby realize the adjusting of size of current.
Protection range of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.
