スイッチの外にスライドスイッチなどもある。[Prior Art] In recent years, as small electronic devices such as electronic desktop calculators (hereinafter referred to as calculators) and electronic translators have become smaller and thinner, keyboard switches using flexible printed circuit boards have come into widespread use. This type of switch has the advantage of being easy to reduce in size and thickness, and also easy to mass produce. In addition to pushbutton type switches, there are also slide switches and other types of switches that use flexible printed circuit boards.

る構造となっている。A conventional slide switch using a flexible printed board uses the slider of the slide switch to press and deform the upper contact point of a flexible printed board made of polyester, etc., similar to a bush-type switch. It has a structure in which it comes into contact with the lower contact consisting of.

れないこともあった。However, due to the nature of the slide switch, it is often fixed in the same position for a long period of time, which has the drawback that the return of the upper contact becomes unstable after changing the position, leading to frequent malfunctions. This tendency was particularly strong when the flexible printed circuit board was made of polyester and the contacts were constructed by pasting metal foil. Further, when the distance between the positions of the switch is close to each other due to miniaturization, mutual interference of the contacts also affects the contact, and it may not be possible to easily restore the contact.

The purpose of the present invention is to provide an electronic device having a slide switch.
