Description
Technical field
The present invention relates to keyboard switch art, refer in particular to a kind of ultra-thin keyboard switch that can steadily press down.
Background technology
Keyboard switch, as the term suggests be a kind ofly apply and be installed on the switch on keyboard, the primary structure of this switch includes pedestal, upper cover, static contact, movable contact spring and push button element, this upper cover and pedestal enclose formation containing cavity, this static contact, movable contact spring and push button element are arranged in this containing cavity, and one end of this push button element is exposed outside containing cavity, by pressing manipulation push button element, make push button element up and down, and then act on movable contact spring by push button element, movable contact spring is contacted with static contact connect or depart to separate.
Above-mentioned existing keyboard switch structure, though effect of user's disconnection or the connection between conducting static contact and movable contact spring can be supplied to, really there is progressive, but but find when reality uses himself structure and serviceability still have many deficiencies, cause existing keyboard switch in practical application, fail to reach best result of use and task performance, now its shortcoming be summarized as follows:
The push button element of the switch of existing keyboard is guide pillar form, make whole product thickness thicker, and push button element is the bottom centre being installed on keycap, when finger only acts on a lateral edges of keycap, push button element cannot steadily press down, and then also cannot realize the conducting of static contact and movable contact spring, use comparatively inconvenience.
Summary of the invention
In view of this, the present invention is directed to the disappearance of prior art existence, its main purpose is to provide a kind of ultra-thin keyboard switch that can steadily press down, and its main purpose is to provide a kind of super-thin keyboard switch, and it effectively can solve the thick and awkward problem of existing keyboard switch thickness.
For achieving the above object, the present invention adopts following technical scheme:
The ultra-thin keyboard switch that can steadily press down, includes pedestal, static contact, movable contact spring, keycap, balancing stand mechanism and resetting device; This static contact and movable contact spring are all arranged on pedestal, static contact has fixed contact, movable contact spring has moving contact, this moving contact and fixed contact setting up and down, this keycap covers static contact and movable contact spring, and balancing stand mechanism and resetting device are all positioned at the below of keycap, and balancing stand mechanism guiding keycap steadily presses down, this keycap or balancing stand mechanism act on movable contact spring and impel moving contact to contact with fixed contact, and this resetting device impels movable contact spring, keycap or balancing stand mechanism to reset.
The present invention compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
Guide keycap by utilizing balancing stand mechanism steadily to press down, this keycap or balancing stand mechanism act on movable contact spring and impel moving contact to contact with fixed contact, and coordinate resetting device to impel movable contact spring, keycap or balancing stand mechanism to reset, instead of the form adopting guide pillar of tradition, make the integral thickness of product thinning, and, no matter finger acts on any position of keycap, balancing stand mechanism all can realize interlock, realize keycap steadily to press down, make static contact be connected sensitiveer with the conducting of movable contact spring, product uses convenient.
