What above-mentioned 201320172454.8 patent disclosed belong in existing more conventional mechanical keyboard, and the key of existing market
What disk switch was all made of be that contact is connected with contact and the tactile keyboard that constitutes switchs, it is existing in keyboard switch and contact
Deficiency existing for the keyboard switch of formula is: existing keyboard switch can only be single conducting, that is, can only be conducting and
Two states are disconnected, keyboard entry function is single, and experience sense is not strong in this way, will cause；Meanwhile existing keyboard switch conducting row
Most of journey be it is fixed, cannot set key conducting stroke or multiple spot stroke conducting.
Summary of the invention
The technical issues of solution of the invention is that it is tight to provide a kind of structure for above-mentioned existing defect in the prior art
Gather, contact good, stability is good, key conducting stroke can be set or the grating type conducting stroke of multiple spot stroke conducting it is adjustable by
Key.
According to the first aspect of the invention, a kind of technical solution that the present invention takes is as follows: a kind of grating type conducting stroke
Turnable keys, including keyseat, key axis and upper cover；The keyseat and the upper cover snap connection and are assembled into shell, the shell
On be formed with the accommodation groove for holding embedding key axis, the key axis is movably embedded in the accommodation groove and the appearance is stretched out on key axis top
It sets affixed with keycap after slot and upper cover, the spring being flexibly connected with keyseat, the axis of the key axis is arranged in the central spindle of the key axis
Core sets grating blocking part far from one end of keycap, and several radial light-conductive holes are formed on the grating blocking part, and the central spindle is set
One end of grating blocking part movable can also be stretched out through the keyseat and the through-hole being located on the pcb board of keyseat bottom end, the PCB
Board bottom end is equipped with the induction LED lamp for providing the light emitting LED lamp of light source and for incuding light source, the light emitting LED lamp and sense
It answers LED light on setting position close to the through-hole and is opposite to each other, the light emitting LED lamp and induction LED lamp are electric with pcb board
Connection；Wherein, the vertically movable light source that grating blocking part can be driven to issue light emitting LED lamp of the central spindle is obstructed or is led
Light, the induction LED lamp can incude the number of grating blocking part barrier light source and the conducting stroke of match settings key.
It is further described as to above-mentioned technical proposal:
In the above-mentioned technical solutions, four side of keyseat is formed with several catching grooves, the close key in each catching groove
Be formed with button platform at seat apical position, four side of upper cover be formed in position with the buckle that matches in number with catching groove, often
