SUMMERY OF THE UTILITY MODEL
In view of the problems raised by the above background art, the present invention is directed to: aims to provide a press conduction structure of a tact switch.
In order to achieve the technical purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a dab pressing down conduction structure of switch, includes panel, frame and dabs the switch, panel and frame pass through the locating pin and closely laminate, dabs the switch mounting on the circuit board in the frame, the panel is equipped with the elasticity panel, the elasticity panel is equipped with three recess, it is provided with three S type shell fragment, three to correspond the recess on the frame S type shell fragment is connected through the gusset end to end, and is three S type shell fragment intermediate position is equipped with the top, the top corresponds the setting with dabbing the switch, and is three there is certain difference in height and round appearance around S type shell fragment and the button that dabs the switch exist and is greater than the button size.
Further inject, three S type shell fragment upside is equipped with the strengthening rib, and S type shell fragment is strengthened to such design, improves structural stability.
Further, the pushing head pressing surface is arc-shaped, so that the switch cannot be influenced when the pushing head is pressed at the edge, and the pushing head pressing surface can be effectively controlled only when the pushing head is pressed at the center.
Further inject, S type shell fragment indent 1.2mm, paste tightly the recess, and with dab switch interval 0.2.mm difference in height, such design, only need gently press the elasticity panel can, need not to heavily press, can improve life.
The utility model has the following beneficial effects:
according to the utility model, the S-shaped elastic sheet is additionally arranged on the light touch switch, a certain height difference exists between the S-shaped elastic sheet and the button of the light touch switch, the periphery of the S-shaped elastic sheet is larger than the size of the button, the pressing surface of the S-shaped elastic sheet is in a circular arc shape, so that the switch cannot be influenced when the switch is pressed at the edge, the switch can be effectively controlled only when the switch is pressed at the center, the edge type pressing of the light touch switch is avoided, the switch is pressed at the center every time, and the service life of the light touch switch is prolonged.

Detailed Description
In order that those skilled in the art can better understand the present invention, the following technical solutions are further described with reference to the accompanying drawings and examples.
As shown in fig. 1 to 3, the press conduction structure of the tact switch of the present invention includes a panel 1, a frame 2 and a tact switch 3, the panel 1 and the frame 2 are tightly attached by a positioning pin, the tact switch 3 is installed on a circuit board in the frame 2, the panel 1 is provided with an elastic panel 11, the elastic panel 11 is provided with three grooves 12, the frame 2 is provided with three S-shaped elastic pieces 21 corresponding to the grooves 12, the three S-shaped elastic pieces 21 are connected end to end by a rib plate, the middle positions of the three S-shaped elastic pieces 21 are provided with a top 22, the top 22 is arranged corresponding to the tact switch 3, the three S-shaped elastic pieces 21 and the tact switch 3 have a certain height difference, and the periphery of the three S-shaped elastic pieces 21 and the tact switch 3 have a circle of shape larger than the size of the button.
In this embodiment, when using a press conduction structure of the tact switch, first, the panel 1 and the frame 2 are tightly attached by the positioning pin, so that the S-shaped elastic sheet 21 is disposed in the groove 12, then the tact switch 3 is mounted on the circuit board, and then the circuit board is mounted in the frame 2, so that the interval between the S-shaped elastic sheet 21 and the button of the tact switch 3 is 0.2mm, because the circumference of the S-shaped elastic sheet 21 is larger than the size of the button, and the pressing surface of the S-shaped elastic sheet 21 is arc-shaped, so that the press cannot affect the switch at the edge, only the press at the center can be effectively controlled, the edge press of the tact switch is avoided, the press switch at each time is at the center position, and the service life of the tact switch is prolonged.
The preferred three S type shell fragment 21 upside is equipped with the strengthening rib, and such design strengthens S type shell fragment 21, improves structural stability, and in fact, also can consider other structures according to particular case and strengthen, improve stability.
The pressing surface of the plug 22 is preferably in the shape of a circular arc, so that the pressing surface does not affect the switch when pressing at the edge, and the pressing surface can be effectively controlled only when pressing at the center, and in fact, other pressing surfaces can be considered according to specific conditions.
Preferably, S type shell fragment 21 indent 1.2mm, paste tight recess 12, and with the light touch switch 3 interval 0.2mm difference in height, such design, only need lightly press elastic panel 11 can, need not to heavily press, can improve life.
The foregoing embodiments are merely illustrative of the principles of the present invention and its efficacy, and are not to be construed as limiting the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
