Abstract
The invention relates to a structural improvement of a key switch. The key switch is mainly composed of a base, a first conducting terminal, a second conducting terminal, a first elastic part, a second elastic part and a moving upper cover. The second elastic part is a spring which is defined by a fixing part, a compressing part and a contact part. The fixing part can be used for locating the second elastic part when the spring is installed on a penetrating part of the first elastic part and the spring is easy to install. When pressure is exerted on the moving upper cover, the moving upper cover is pressed to compress the first elastic part to drive the second elastic part to move. When the contact part of the second elastic part is conducted with the first conducting terminal and the second conducting terminal in a contact mode, a distance stroke for downward pressing still exists. When the moving upper cover is continuously pressed, the compressing part is pressed, so that the contact part is conducted with the first conducting terminal and the second conducting terminal more tightly in a contact mode. Thus, unstable conducting caused by insufficient pressing force can be avoided when the key switch is used. Meanwhile, feedback feelings can be generated by pressing and releasing the first elastic part (conducting silica gel).
Description
Technical field
The present invention is about a kind of button being used on keyboard, espespecially a kind of structural improvement that can promote the key switch of button conducting stability.

Embodiment
Below in conjunction with embodiment, further illustrate content of the present invention.
Refer to shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5 the schematic perspective view of invention preferred embodiment, perspective exploded view, another angle perspective exploded view and generalized section.The structural improvement of a kind of key switch of the present invention, each key switch 2 is installed in a circuit board that is provided with a plurality of weld parts, each key switch 2 is mainly by base 20, the first conducting terminal 21, the second conducting terminal 22, the first elastic component 23, the second elastic component 24 and movable top lid 25 form, wherein base 20 forms a holding part 200, wherein holding part 200 is mainly for the first conducting terminal 21 and the second conducting terminal 22 (being arranged at base 20 belows) being set and furnishing for the first elastic component 23, in addition, aforesaid the first elastic component 23 (for electric silica gel) is arranged at holding part, and the first elastic component 23 forms the portion of running through 230 of corresponding first conducting terminal 21 and the second conducting terminal 22 positions, the second elastic component 24 (for spring) defines one and is arranged at this first elastic component 23 and is positioned at the fixed part 240 that this runs through portion 230 tops, one is extended and is arranged at this compression unit that runs through portion 230 242 and by these compression unit 242 extensions and is positioned at the first conducting terminal 21 and the second conducting terminal 22 tops by this fixed part 240, can be for the contact site 244 of the first conducting terminal 21 and the second conducting terminal 22 electric connections, the more important thing is, because aforementioned fixed part 240 is greater than the entrance (the second 24 of elastic components present T-shaped aspect) of the portion of running through 230, make the second elastic component 24 can be arranged on the portion of running through 230 and can not drop or be shifted, also the therefore height that be shorter in length than this first elastic component 23 of compression unit 242 when not compressed.In addition, when the first elastic component 243 is pressed or discharges, the elastic effect that sees through monolithic conductive silica gel allows user can obtain feedback sense, and in other words, user can the very clear press condition of knowing key switch when pressing or decontroling.
Moreover, aforesaid movable top lid 25 is installed in this base 20, and this movable top lid 25 forms a recess 252 for sheathed this fixed part 240, in addition, a plurality of overhead kick of movable top lid 25 formation portion 254, and the stop section 204 that aforesaid base 20 forms a plurality of guide grooves 202 and is positioned at this guide groove 202, when movable top lid 25 is assembled in base 20, movable top lid 25 can see through overhead kick portion 254 and move in guide groove 202, and prevents that by stop section 204 movable top lid 25 from departing from base 20.
By aforementioned structure, can be had a clear understanding of, while not compressing in pressing conducting (please refer to Fig. 6), movable top lid 25 can be pressed the first elastic component 23 downwards, the first 23 of elastic components are out of shape in advance and allow contact site 244 on the second elastic component 24 touch the first conducting terminal 21 and the second conducting terminal 22 and conducting simultaneously, but now compression unit 242 is not yet compressed, when the first elastic component 23 is by compression made contact site 244 touch first conducting terminal 21 and second conducting terminal 22 to form conducting by the compression unit 242 of (and please refer to Fig. 7) second elastic component 24 after pressing completely downwards.Thus, the compression that sees through compression unit 242 is stablized to promote whole signal.
Thus, because the second elastic component 24 is spring structure, and because the compression unit 242 of the second elastic component 24 is shorter than the first elastic component 23 height, while causing compression unit 242 to be stressed, can produce relative deflection or decrement, the elasticity that sees through spring itself makes push switch press or all can control exactly during release pressure the contact relation between the second elastic component 24 and the first conducting terminal 21 and the second conducting terminal 22, and then the stability of lifting key switch when face contact, user is seen through when the first elastic component is pressed or discharges and all can produce and feed back sense simultaneously.
The first conducting terminal 21 of the present invention and the second conducting terminal 22 can be assembling mode and are installed on base 20, or other utilization is imbedded, and ejaculation is integrally formed is fixed on base 10 by the first conducting terminal 21 and the second conducting terminal 22, except aforementioned two kinds of modes, also can see through contact and carry out and the connecting of circuit board in the mode of circuit board, this kind of mode just do not need also can reach and connect object through circuit board.
