Hall switch is to utilize Hall element to the changes of magnetic field of its present position and produce analog signal; Utilize hall principle to produce the Hall toggle switch in the prior art, the Hall toggle switch is that magnetic conduction sheet is placed near the magnetic patch, and magnetic conduction sheet links to each other with a circuit board; Rotate magnetic patch; The magnetic flux that passes magnetic conduction sheet changes, and the direction of rotation is different, and the electrical potential difference of generation is also different; Circuit board is according to different electrical potential difference output various signals; Advantages such as that the Hall toggle switch has is contactless, long life, but in the practical application because magnetic conduction sheet does not adopt enclosed construction to make the magnetic patch leakage field comparatively serious, make that sensitivity is not high and waveform output is relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of Hall switch, it compared with prior art has the employing enclosed construction, has reduced the leakage field of magnetic patch, has improved the sensitivity of Hall element.
To achieve these goals, the invention provides a kind of Hall switch, comprise, a housing is characterized in that, being installed in the said housing an of magnetic patch; At least one magnetic conduction sheet winding is in the said magnetic patch outside, and said magnetic patch can be with respect to said magnetic conduction sheet motion; Said magnetic conduction sheet have two exits, said two exits do not contact mutually.
Aforesaid Hall switch, wherein, said magnetic patch can rotation in said magnetic conduction sheet.
Aforesaid Hall switch, wherein, the outer surface of said magnetic conduction sheet is arranged with a magnetic isolation plate.
Aforesaid Hall switch, wherein, a rocking bar connects said magnetic patch, is used to rotate said magnetic patch.
Aforesaid Hall switch, wherein, said magnetic patch is a column, said magnetic conduction sheet winding is in the side of this column magnetic patch.
Aforesaid Hall switch, wherein, said magnetic conduction sheet is a ring-type.
Aforesaid Hall switch, wherein, said exit links to each other with a Hall circuit plate.
Aforesaid Hall switch, wherein, said magnetic conduction sheet does not contact with said magnetic patch mutually.
Owing to adopted technique scheme; Hall switch of the present invention has solved in the prior art because the leakage field that magnetic conduction sheet does not adopt enclosed construction to cause comparatively seriously causes the problem that Hall switch sensitivity is not good, output waveform is relatively poor; A kind of Hall switch that adopts the enclosed construction magnetic conduction sheet is provided; Make the leakage field phenomenon obtain very big alleviating, and then increased the sensitivity of Hall switch greatly.
