The upper surface contact of confined planes and opening.
In a preferred embodiment：Also there is LED light, light-emitting surface is towards on the cavity in the Switch main body
That opening face of side.
In a preferred embodiment：The outer wall of the button cap is coated with black paint, and the black paint is in button cap
There is a white space, the light that the LED light is sent is appeared from the white space at outer wall amount axle center.
Compared to the prior art, technical scheme possesses following advantageous effect：
It is 1. multiple by elasticity in Switch main body for the elastic rib of cancel button the present invention provides a kind of key switching structure
Position device its own resilient enables button cap to move up and down, and button cap cooperatively forms guide surface with fixed seat by circular conical surface,
Ensure that button cap can move along a straight line up and down, will not tilt.
2. the present invention provides a kind of key switching structure, radially outward stretch out of button cap sidewall bottom forms two
Confined planes are coordinated, it is ensured that button cap is without departing from fixed seat by the /V of confined planes and fixed seat.This design will not be blocked
Button cap not only increases switch service life, but also improves using feel.
3. the present invention provides a kind of key switching structure, there is LED light at the center of Switch main body, and button is using transparent
Plastics, in outer surface spraying black paint, black paint generates one piece of white space at axle center using laser engraving so that indicator light
Light broken forth by white space, so as to add keypress function, reduce part, appearance more precision and elegance.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
With reference to figure 1-4, a kind of key switching structure, it is characterised in that including fixed seat 1, button cap 2, Switch main body 3；Institute
Cavity 11 of the fixed seat 1 with an accommodating button cap 2 is stated, the both ends of the cavity 11 are respectively opening face；The button cap 2 is logical
The opening face for crossing top is placed in cavity 11, and the Switch main body 3 is entered by the opening face of lower section in cavity 11；It is and described
The certain gap of the side wall of cavity 11 and the side wall parallel, spaced-apart of button cap 2 is formed along the pressing of button cap 2 and rebound direction
Guide surface；When pressing the button cap 2, the button cap 2 moves axially down in cavity 11, is connect with Switch main body 3
It touches and trigger switch body 3；
In addition, there is elasticity reset device, when the button cap 2 moves axially down, institute in the Switch main body 3
Elasticity reset device deformation accumulation elastic reset power is stated, so as to which button cap 2 be driven axially to be reset to confined planes upwards with opening
The upper surface contact of mouth.
The side wall of the button cap 2 extends radially outward out the confined planes 21 of two rotational symmetry distributions, the chamber
The side wall of body 11 has and the 21 matched opening of confined planes；The confined planes 21 are stretched into opening, and in the opening
Upper surface along vertical direction /V coordinate so that the button cap 2 is always positioned in cavity 11.The number of the confined planes 21
Amount or one, or three or three or more, designer can voluntarily adjust according to actual needs, belong to this
The simple replacement of embodiment.
A kind of above-mentioned key switching structure is the elastic rib of cancel button, by elasticity reset device in Switch main body 3 certainly
Body elastic force enables button cap 2 to move up and down, and button cap cooperatively forms guide surface with fixed seat 1 by side wall, it is ensured that button
Cap 2 can move along a straight line up and down, will not tilt.
And radially outward stretch out of 2 sidewall bottom of button cap forms two confined planes 21, by confined planes 21 with fixing
The /V cooperation of seat 1, it is ensured that button cap 2 is without departing from fixed seat 1.This design will not block button cap 2, not only increase out
Service life is closed, and is improved using feel.
In the present embodiment, the side wall of the cavity 11 and the side wall of button cap 2 are respectively circular conical surface.Or cylinder
Face depending on the shape of the side wall of button cap 2 itself, is as long as the sidewall shape of cavity 11 is consistent with the sidewall shape of button cap 2
It can.
The opening is axially upwardly extended from the end face of 11 other end of cavity.Install button cap 1 when, button cap 1 from
It axially installs upwards the end face of 11 other end of cavity so that confined planes 21 enter from the end face of the other end of cavity 11 to be opened
In mouthful.This completes the installations of button cap 1.
In the present embodiment, also there is LED light 31, light-emitting surface is towards on the cavity 11 in the Switch main body 3
That opening face of side.
The outer wall of the button cap 2 is coated with black paint, and the black paint has at 2 outer wall amount axle center of button cap
There is a white space 22, the light that the LED light 31 is sent is appeared from the white space 22.
Since there is LED light 31 at the center of Switch main body 3, and button cap 1 is made of transparent plastic, meanwhile, it presses
The outer surface spray black paint of keycap 1, black paint generate one piece of white space at axle center using laser engraving, thus can be with
So that the light of LED light 31 is broken forth by white space 22, so as to add keypress function, part is reduced, appearance is more
Precision and elegance.
The foregoing is merely present pre-ferred embodiments, therefore the technical scope of the present invention cannot be limited according to this, therefore Fan Yiben
The equivalent changes and modifications that the technical spirit and description of invention are made, in the range of should all belonging to technical solution of the present invention.
