Problems solved by technology

In this case, although it is manufactured in a normal state, when the capacitive sensing switch module is actually used after the shipping process, it may cause a defective product
[0008] Third, since the required components including the touch sensor IC, active and passive components are separately mounted on the PCB 20, a pin insertion process as well as an epoxy molding process must be performed, thus making the entire Complicates the manufacturing process and thus makes miniaturization of components difficult

Embodiment Construction

[0028] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, since the same reference numerals denote the same elements throughout the drawings, descriptions of the same elements will not be repeated.

[0029] figure 2 It is an exploded perspective view of the capacitive switch module according to the first embodiment of the present invention. refer to figure 2, the base 140 serving as a frame in the prior art is in the form of a hollow cubic case that is open upwards and downwards. The mounting plate 144 is installed horizontally in the hollow space of the base 140 . Two opposite sides of the four sides of the mounting plate 144 are recessed so as to jointly form a notch 143 through the inner wall of the base 140 . The protruding piece 132 of the metal plate 130 with the sensing electrode passes through the notch 143 which can pass through and is fixed. Accordingly, th...

Abstract

A capacitive switch module is disclosed, which is capable of achieving simplification of fabricating process and miniaturization, preventing deterioration of sensitivity and reducing the possibility of malfunction, and further capable of reducing inferior goods caused by impacts applied during the transportation. The most distinctive feature of the capacitive switch module according to the present invention is in an integrated structure of a metal plate serving as a sensing electrode, a base serving as a bracket, and a capacitive sensor IC chip. Also, a lower cover capable of relieving an impact applied from a lower part to the capacitive sensor IC chip is optionally mounted.

Description

technical field [0001] The present invention relates to a capacitive switch module, and in particular to such a capacitive switch module, which can realize the simplification and miniaturization of the preparation process, avoid sensitivity deterioration and reduce the possibility of failure, and can also reduce the Defective products caused by collision. Background technique [0002] Recently, the popularity of mobile devices such as cell phones has skyrocketed in surprising fashion as more and more mobile devices employ touch sensors. Due to the widespread application of touch sensors in the mobile device market, the market for capacitive switch modules as a component part of touch sensors has also grown, and its application is not limited to the field of home appliances. Compared with traditional mechanical switching systems, capacitive switches have many advantages, including visual design, excellent construction, semi-permanent life, durability, etc. With the active c...
