Touch switch

Abstract

The invention provides a touch switch which can not only improve the operating stability and reliability of the touch switch body but also ensure operating convenience, reliability and attractive appearance of a machine provided with the touch switch. The touch switch is characterized in that a connection component (30a) for realizing conducting connection between a conductive induction component (30) and a printed substrate (19) is integrally connected with the induction component, wherein the connection component has elasticity and the induction component is pressed on an outer shell (17) for switching operation. Accordingly, the detection deviation of the electrostatic capacity during switching operation of people can be reduced and the induction component can be fixed on the printed substrate by a simple structure, thereby reducing the assembling deviation and improving the reliability of products.

Description

technical field [0001] The present invention relates to a touch switch for switching operation by detecting the electrostatic capacity of a human body, and a refrigerator provided with such a touch switch on a door or the like. Background technique [0002] In recent years, with the diversification of the functions of home appliances, the number of switches provided on the surface of home appliances and the like has been increasing. From the standpoint of convenient operation and reduction of operating parts to achieve rationality, a plurality of operation switches are usually arranged as close as possible to achieve centralized arrangement. [0003] Such an example is shown in Japanese Patent Laid-Open Document 2007-040660, which shows a technique related to a plurality of operation switches in a refrigerator. [0004] Figure 10 A schematic diagram of the appearance of the control substrate unit in this conventional refrigerator is shown in . [0005] Such as Figure 10 ...

AI Technical Summary

Problems solved by technology

[0012]In order to solve the above-mentioned problems of key-type switches, although some people have proposed a touch switch scheme that detects the electrostatic capacity of the human body to perform switch operations, but for the sake of exerting practical The convenience of operation, reliability, and aesthetic appearance of the machine equipped with such a touch switch have not been specifically mentioned so far.
