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 light-emitting diode (23) which emits lights when an induction part (18) detects the electrostatic capacity, the induction part is encircled by a box body (24) with a double-layer structure, the light-emitting diode is arranged between two layers of side walls of the box body, and the induction part is arranged in the inner wall (24a). A user can confirm the detection condition through a visual mode by enabling the periphery of the induction part to emit the lights when the electrostatic capacityof a human body is detected.

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 ...
