Problems solved by technology

[0009] Furthermore, in the case where only the key top is made of a metal sheet, when the metal sheet is provided with a decorative notch area, for example, the space inside the line like 0, 6, and 8 has a part of the figure that is divided from the space on the outside. , it is necessary to reserve the connecting part used to connect the inner metal part of the notch area and the outer metal part, therefore, it is impossible to make a figure that completely separates the inside and outside of the notch area, and a decorative problem occurs (refer to Figure 4 Figure to the left of the arrow)

Abstract

A key top (4) used for push-button switches of mobile electronic devices comprises a generally thin metal sheet (6) and outer layer sheets (8a, 8b) joined to one or both surfaces of the metal sheet (6) and made of a flexible material. A key sheet (2) comprises the key top (4) and a sheet-like key base (10) joined to the key top (4) and made of an elastic material. A method of manufacturing the key top and the key sheet is also provided.

Description

technical field [0001] The present invention relates to components used in push button switches of portable electronic devices such as mobile phones and portable information terminal devices (PDA: Personal Digital Assistance, personal digital assistants), and a manufacturing method thereof. The key top (キ—ト) for opening and closing the contacts ツ プ), key sheet (キ—シ—ト), and a manufacturing method thereof. Background technique [0002] Key sheets are widely used as parts of button switches of portable electronic devices such as mobile phones and portable information terminal devices (PDAs). The key sheet is generally formed by bonding a key top made of a resin material and a key seat made of an elastic material such as silicone rubber or thermoplastic elastomer. [0003] In recent years, along with miniaturization of portable electronic devices, further thinning of push button switches has been demanded, and along with this, thinning of key tops and key sheets has also been ...
