Description
Technical field
The present invention relates to key switch, specially a kind of thin type key switch.
Background technique
Currently, universal portable computer keyboard is all the membrane keyboard with scissor leg structure, driving key can make to switch
It moves up and down, to realize the conducting and closure of switch, which includes by system, face-piece and pedestal, the face-piece button
Together in sound piece and contact chip on the pedestal, is additionally provided in the pedestal, the sound piece is located at the side of pedestal, described to connect
Contact is located at the centre of pedestal, and the contact on the contact chip is located at the lower part of contact chip.The key switch of this kind of structure is in reality
Border has the disadvantage that 1, contact chip is located among pedestal in, and sound piece is located at a side of pedestal, presses through under by system
Discontinuity in journey；2, discontinuity will affect the service life of contact chip；3, contact is located at contact chip lower part, pushes by system
Reaction is slow in the process, lacks feel；4, key switch height is higher, it is difficult to meet the development trend of slimming；5, contact chip position
Among pedestal, pedestal light transmission is influenced.
Summary of the invention
Low, uniform force that the present invention provides a kind of height, the thin button that the service life is long, bottom light transmission and user experience are good
Switch.
The present invention can be achieved through the following technical solutions:
A kind of thin type key switch, including face-piece and pedestal, the face-piece are fastened on the pedestal, are set in the pedestal

Positioned at the side of pedestal.Contact chip in the prior art is moved to the side of pedestal by thin type key switch of the present invention from pedestal middle position
On the one hand portion effectively improves the uniform force degree that process contact piece and sound piece are pushed by system, promote components uses the longevity
Life, while improving the stability of key switch in use；On the other hand pedestal middle section is available, convenient for saturating
Light makes key switch in use can be from bottom light transmission, and meet user dazzles cruel demand.
Further, the outer profile of first slot position and the second slot position protrudes base body outer profile certain distance.Institute
The first slot position and the second slot position protrusion pedestal certain distance are stated, the stability of pedestal is effectively promoted.
One of preferred embodiment as thin type key switch of the present invention, first slot position and the second slot position are symmetrically distributed in
The opposite sides of pedestal, effectively ensures to push the uniform force degree of process contact piece and sound piece by system, and uniform force degree mentions
Height, effectively ensures the service life of components, while improving the stability of key switch in use
Further, it is additionally provided with the first terminal and Second terminal for connecting with circuit board on the pedestal, described
One terminal and Second terminal are symmetrically distributed in the other opposite sides of pedestal.The first terminal and Second terminal are symmetrical,
Ensure uniform force, effectively promotes the terminal service life.
One of preferred embodiment as thin type key switch of the present invention, first slot position and the second slot position are in 90 degree of distributions
In the adjacent two sides of pedestal.It is additionally provided with the first terminal and Second terminal for connecting with circuit board on the pedestal, described
One terminal and Second terminal are distributed in the other adjacent two sides of pedestal in 90 degree.
Further, the contact chip includes tongue piece, and the middle part of the tongue piece is equipped with contact, and the contact top is equipped with touching
Point, tongue piece top two sides are respectively equipped with Undee shrapnel, and the Undee shrapnel is located at the two sides of contact.The contact chip
Contact be arranged on contact top, the structure setting on tongue piece top is arranged in Undee shrapnel, make contact chip formed handstand shape set
In in the first slot position, the structural relation of the upright placement of traditional contact chip is overturned, the contact chip after handstand is by the prior art
The lower part that contact is located at contact chip is changed to the top that contact is located at contact chip, makes by system relatively early contact touching during the depression process
Point, formed effective arm, reduce compressing time, meanwhile, it is improved after contact chip, tongue piece bending amplitude is small, and precision is easier to
In control, it is easier to mass production, longer life expectancy；The contact two sides are used to form setting for the Undee shrapnel of wave feel
It sets, pressing process Wave feel is made to form morning, effectively promotion user experience；The contact chip, which stands upside down, to be placed, and is effectively reduced
The height of contact chip, and then reduce the height of switch, switch whole height is low.
Further, the face-piece be equipped with for by system across press drilling, the middle of the base be equipped with upward pillar,
Spring is arranged on the pillar, the spring top is connected with by system.
Further, the middle of the base is equipped with loophole.The pillar is hollow setting, the pillar hollow space shape
At loophole.The setting of the middle of the base loophole can allow light through pedestal, form keyboard in use bright
Light enhances user experience.
Thin type key switch of the present invention, have it is following the utility model has the advantages that
The first, uniform force degree is good, the service life is long, thin type key switch of the present invention will in the prior art contact chip from pedestal
Between position move to the side of pedestal, on the one hand effectively improve the uniform force degree that process contact piece and sound piece are pushed by system,
Promote the service life of components；
The second, stability is good, and contact chip moves on side from centre, effectively increases the spacing of sound piece and contact chip, into
And improve the stability of key switch in use；
Pedestal middle section, is on the other hand available by third, bottom light transmission, is convenient for light transmission, is using key switch
In the process can be from bottom light transmission, meet user dazzles cruel demand；
4th, compressing time is short, and the contact and Undee shrapnel in thin type key switch of the present invention on contact chip are from tradition
Setting in contact chip is changed to setting on contact chip top on contact chip top, so that contact chip is formed handstand shape and is placed in the first slot
In position, the structural relation of the upright placement of traditional contact chip has been overturned, has made to contact contact by system is relatively early during the depression process, be formed
Effective arm reduces compressing time；
5th, high bottom is low, and the structure design of contact chip effectively reduces the height of contact chip, and then reduce switch
Highly, switch whole height is low.
6th, user experience is good, and on the one hand the contact two sides are used to form the setting of the Undee shrapnel of wave feel,
Pressing process Wave feel is set to form morning, effectively promotion user experience, the setting of the middle of the base loophole described in another party can
To allow light through pedestal, so that keyboard is formed light in use, enhance user experience.
