Description
Technical field
The utility model is related to button technical field, more particularly to a kind of button, and the input comprising above-mentioned button
Device.
Background technology
Current existing button generally includes key main body, elastic arm and conductive particle and constitutes, button pressed, key main body
Elastic arm is compressed, and conductive particle presses board sheet metal, turns on electrical functionality.Unclamp button, the rapid resilience of elastic arm, conductive particle
Board sheet metal is left, electrical functionality disconnects.But, current existing press-key structure button touch feeling is bad, so someone
Propose and the top end face of key main body is designed to arcwall face, but ought obliquely press the key main body that top end face is arcwall face
When, because the conductive particle below key main body does not put key main body center of gravity, therefore cause conductive particle to touch less than board sheet metal,
So that disabler, functional reliability is low.Additionally, when button is pressed, being easily stuck in upper cover part, it is impossible to enough resiliences, from
And cause touch-switch to fail.And, when button is pressed, conductive particle is touched less than board sheet metal sometimes, causes function to be lost
Effect.
Utility model content
(1) technical problem to be solved
The purpose of this utility model is to provide a kind of button, and the button touch feeling is felt good and functional reliability is high.
(2) technical scheme
In order to solve the above-mentioned technical problem, the utility model provides a kind of button, wherein, including keying body, support
Plate, and the elastic skew wall between keying body and supporting plate is connected to, conductive particle is provided with below keying body, it is described
The top end face of keying body is arcwall face, and the center of the conductive particle is located at a vertical curve with the center of gravity of the keying body
On.
Wherein, shape has angle β between the bottom surface of the conductive particle and supporting plate.
Wherein, 25 °≤β≤45 °.
Wherein, angle of at least one of four sides of the keying body between supporting plate is α, wherein α>

After being contacted with board sheet metal (not shown), switch closure, circuit is started working, and now finger unclamps the top of keying body 1
Face, in the presence of restoring force (screen resilience), button return, whole work is completed.
Advantageously, shape has angle β between the bottom surface of conductive particle 3 and supporting plate.It is preferred that 25 °≤β≤45 °.
During in order to ensure to press, button will not be stuck in upper cover part, it is impossible to enough resiliences, so as to cause touch-switch to fail,
It is preferred that angle of at least one of four sides of keying body 1 between supporting plate is α, wherein α>90 °, preferably 93 °≤α
≤97°。
It is preferred that keying body 1 is made up of silica gel, to cause key tops face softer, when operation is touched, feel is more comfortable.This
Outward, elastic skew wall 2 is made up of rubber.Further, it is preferable to elastic skew wall 2 uses makrolon and acrylonitrile-butadiene-benzene second
Alkene copolymer and mixture are made, and the button is made up of injection moulding.
The invention also discloses a kind of input unit, it includes circuit board and is arranged at least the one of circuit board
Individual above-mentioned button.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
