Problems solved by technology
However, in the lighting structure of the above-mentioned conventional operation key, since the light storage portion 61b is provided in the above-mentioned operation key 61, it is necessary to avoid the above-mentioned substrate with movable contacts on the path from the above-mentioned LED 62 to the above-mentioned operation key 61. 51, the above-mentioned light guide member 64 is additionally provided, therefore, there is a problem that the number of parts increases and miniaturization cannot be realized
[0006] Furthermore, since the structure is such that the above-mentioned light storage portion 61b is formed on the above-mentioned operation key 61 itself, there is a problem that the area of the light storage portion is small, and it is difficult to increase the amount of light emitted.

This invention provides a sheet attached with a contact-point as well as a switchgear capable of emitting light from a light storage part with no separate light-guide member for smaller size, while the amount of emitted light from the light storage part is increased. There are provided a first sheet 1 comprising a reversible swollen part 1a, a movable contact point 3 provided inside the swollen part 1a, and a second sheet 4 which is, made of a sheet containing light-storage or night-grow pigment and stacked on the first sheet 1 as one body. The second sheet 4 is provided with a notch 4a which allows counterturn of the swollen part 1a when the first sheet 1 is pressurized.
Description
technical field [0001] The present invention relates to a substrate with contacts used in an operation panel of a portable electronic device and a switch device using the same, and particularly relates to an illumination structure of an operation key when operating in a dark place. Background technique [0002] In the conventional lighting structure of operation keys, a light storage unit is arranged on the operation key on the adjustment side provided on a substrate with contacts, and the operation keys are illuminated by LEDs. The structure of this past switchgear with light storage lighting is shown in Figure 9 . [0003] In the figure, the switch device has the following components: a circuit board 58, which is used to arrange fixed contacts 59, 60; a substrate 51 with movable contacts, which is superimposed on the circuit board 58; an operation key 61, which is connected with the The substrate 51 of the movable contact is combined; the LED62, which is used as a light ...
