Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described using the drawings.

[0025] figure 1 is a sectional view of a movable contact body according to an embodiment of the present invention, figure 2 is a view of the lower surface of the substrate.

[0026] Such as figure 1 as well as figure 2 As shown, the movable contact body includes a movable contact 11 and a substrate 12 . The movable contact 11 is made of an elastic thin metal plate. The movable contact 11 is the same as the conventional structure, and its outer shape is circular, and the lower part is open, and the upper part is convex. The substrate 12 is made of an insulating film. The adhesive 13 is applied by printing on almost the entire lower surface of the substrate 12 . The upper surface of the dome-shaped apex portion 11A of each movable contact 11 is adhered and held with an adhesive 13 . A plurality of movable contacts 11 are arranged at predetermined positions on the substrat...

Abstract

The present invention discloses a small movable contact body and a panel switch that can prevent the outer edge from peeling off even if the distance between the outer edge of the substrate and the movable contact is narrowed. The movable contact body of the present invention includes a movable contact and a base sheet. The movable contact is an elastic metal plate formed in a dome shape. The base sheet is a dome-shaped vertex portion of the movable contact bonded with an adhesive on the lower surface. , an insulating film that holds the movable contact at a predetermined position, and an auxiliary is provided on a portion of the annular portion corresponding to the non-adhesive portion that becomes the outer edge side of the substrate at the corresponding portion of the movable contact near the outer edge of the substrate Adhesive, the movable contact arranged near the outer edge including the auxiliary adhesive is bonded and held on the substrate.

Description

technical field [0001] The present invention relates to a movable contact body for a panel switch constituting an operation panel or the like of various electronic devices, and a panel switch constituted using the contact body. Background technique [0002] In recent years, portable electronic devices such as mobile phones and PDAs (Personal Digital Assistants) are widely used. These electronic devices are being miniaturized in order to improve portability, etc., and panel switches used in the operation panel portion thereof are also required to be reduced in size. use Figure 4 ~ Figure 6 A conventional movable contact body used in such a panel switch and a panel switch configured using the contact body will be described. Figure 4 is a sectional view of a conventional movable contact body, Figure 5 is an exploded oblique view of the figure, Image 6 It is a cross-sectional view of a panel switch constructed using this movable contact body. [0003] exist Figure 4 as...
