Touch switch

Abstract

The invention provides a touch switch which can improve the operation stability and the reliability per se and also can ensure the operation convenience, the reliability and the appearance beauty of machinery equipment provided with the touch switch. The touch switch is internally provided with a box body (24) covering the periphery of an induction part (18), the induction part is connected with a connecting part (21) under a state that the upper surface (18a) of the induction part is higher than the upper surface (24c) of the box body, and the connecting part is an elastic part. After the box body is fixed on a printed substrate, the induction part after being connected with the connecting part is easy to be fixed on the printed substrate, and the difference of assembly operation also can be reduced. Because the induction part is arranged at the position protruding over the upper surface of the box body, tight attaching type fixation can be realized between a part arranged on the upper surface of the induction part and supplied for people to touch and the induction part, and the detection deviation of an electrostatic capacity can be lowered.

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.
