Description

The ultra-thin keyboard switch that can steadily push
Technical field
The present invention relates to keyboard switch art, a kind of ultra-thin keyboard switch that can steadily push is referred in particular to.
Background technology
Keyboard switch, as the term suggests it is a kind of to apply and be installed on the switch on keyboard, the primary structure bag of this switch Pedestal, upper lid, static contact, movable contact spring and push button element are included, lid and pedestal enclose to form accommodating cavity on this, the static contact, dynamic touched Piece and push button element are arranged in the accommodating cavity, and one end of the push button element is exposed outside accommodating cavity, by pressing manipulation push button element, are made Obtain push button element up and down, and then acted on by push button element on movable contact spring so that movable contact spring contacts connection with static contact or de- From separately.
Above-mentioned existing keyboard switch structure, disconnects or turns between static contact and movable contact spring though being provided to user Effect of connection, really with progressive, but has been found that in actual use and is still suffered from its own structure and performance There are many deficiencies, cause existing keyboard switch in practical application, fail to reach optimal using effect and task performance, it is existing Its shortcoming is summarized as follows:
The push button element of the switch of existing keyboard is guide pillar form so that whole product thickness is thicker, and push button element is peace Bottom centre loaded on keycap, when finger acts only on a lateral edges of keycap, push button element can not be pushed steadily, and then also without Method realizes the conducting of static contact and movable contact spring, and use is more inconvenient.
The content of the invention
In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide one kind steadily to be pushed the present invention Ultra-thin keyboard switch, its main purpose is to provide a kind of super-thin keyboard switch, and it can effectively solve existing keyboard switch The problem of thickness is thick and inconvenient for use.
To achieve the above object, the present invention is using following technical scheme:
A kind of ultra-thin keyboard switch that can steadily push, includes pedestal, static contact, movable contact spring, keycap, Balancing rack mechanism And resetting-mechanism;The static contact and movable contact spring may be contained within pedestal, and static contact has stationary contact, and movable contact spring has dynamic touch Point, the movable contact and stationary contact are setting up and down, and the keycap covers static contact and movable contact spring, Balancing rack mechanism and the equal position of resetting-mechanism In the lower section of keycap, Balancing rack mechanism guide keycap is steadily pushed, and the keycap or Balancing rack mechanism are acted on movable contact spring and promoted Movable contact is contacted with stationary contact, and the resetting-mechanism promotes movable contact spring, keycap or Balancing rack mechanism to reset.
The present invention has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technical proposal Understand:
Steadily pushed by using Balancing rack mechanism guide keycap, the keycap or Balancing rack mechanism are acted on movable contact spring and promoted Movable contact is contacted with stationary contact, and coordinate resetting-mechanism to promote movable contact spring, keycap or Balancing rack mechanism to reset, instead of tradition Use guide pillar form so that the integral thickness of product is thinned, also, no matter finger acts on any position of keycap, puts down Linkage can be achieved in the frame mechanism that weighs, and realizes that keycap is steadily pushed so that the conducting connection of static contact and movable contact spring is sensitiveer, production It is more convenient that product are used.
