Embodiment approach 1

[0029] figure 2 A plurality of drawings shown in FIG. 5 show a plurality of structural elements of the tact switch for electronic components according to the first embodiment of the present invention and their combination forms. The structure of the tact switch for electronic components of the present embodiment includes : The upper pattern 200 is formed by a plate-shaped conductor with a specified thickness that can be energized; the lower pattern 220 is formed by a plate-shaped conductor with a specified thickness that can be energized; The non-conductive insulator between them is formed; and the dome switch 240 (hereinafter referred to as the metal dome) is arranged on the upper part of the above-mentioned upper pattern.

[0030] exist figure 2 In the upper pattern 200, a circular electrode portion 210 is provided in the center of the upper pattern 200, and corrosion occurs by etching the peripheral portion of the electrode portion 210, so that the electrode portion 210 ...

Embodiment approach 2

[0053] Figure 6 A plurality of drawings shown to 9 show a plurality of structural elements and their combination forms of the tact switch for electronic components according to the second embodiment of the present invention. This embodiment is also like Embodiment 1, and the tact switch for electronic components provided The structure of the touch switch includes: the upper pattern 200' is formed by a plate-shaped conductor with a specified thickness that can be energized; the lower pattern 220' is formed by a plate-shaped conductor with a specified thickness that can be energized; A non-conductive insulator located between the upper pattern and the lower pattern is formed; and a dome switch 240 (hereinafter referred to as a metal dome) is disposed on the upper portion of the upper pattern.

[0054] The substantial difference between Embodiment 2 and Embodiment 1 lies in the shapes of the upper pattern 200 ′, the lower pattern 220 ′, and the insulating plate 230 ′.

Abstract

The present invention relates to a tact switch for an electronic component, and provides a tact switch for an electronic component, comprising: an upper pattern and a lower pattern formed of a plate-shaped electrifiable conductor of a predetermined thickness; an insulation panel positioned between the upper pattern and the lower pattern and formed of an insulator, which does not conduct electricity; and a dome switch placed at the upper part of the upper pattern, wherein the upper pattern has a circular electrode unit at the center thereof, the electrode unit protrudes at the center of the upper pattern by corroding a peripheral part thereof through etching, and a pair of corresponding end points at a circular surface of the electrode unit are connected to each other such that a first electrode and a second electrode having different polarities are symmetrically formed around the connection, the pair of corresponding end points at a circular surface of the electrode unit are connected by being corroded through etching, the connection is an insulation unit for electrically insulating the first electrode and the second electrode, the insulation unit alternately enters an area of the first electrode and an area of the second electrode from a virtual diameter line interconnecting both ends points at the circular surface of the electrode unit, and respectively extends in the directions of the first electrode and the second electrode so as to be formed into a sinuous shape curving at least a plurality of times, and the first and second electrodes respectively include, due to the insulation unit, extended parts having a shape sequentially extending in mutually opposing directions so as to be fitted and engaged with each other around the insulation unit.

Description

technical field [0001] The present invention relates to a tact switch for an electronic part that can implement surface mount technology (SMT) on a circuit board, and more particularly to a tact switch for an electronic part that has a high button contact rate and an assembled It is simple and the unqualified rate is significantly reduced. Background technique [0002] As we all know, the tact switch for electronic components executes the opening and closing action of the circuit through slight contact. It has the advantages of precise and easy opening and closing of the circuit, and the advantages of simple structure. It is a representative switch used in various modern electronic products. [0003] Recently, it is mainly used for portable communication devices such as cellular phones and various miniaturized notebooks, portable boxes, MP3 and other increasingly sophisticated and miniaturized products, which are mainly used in the trend of miniaturization. The development ...
