摘要:
A link member (14) consists of a set of frame bodies (15, 16) assembled in an X shape when seen from the side so as to be swingable each other. A base member (13) is provided to support the link member (14). At least one of the link member (14) and the base member (13) is an elastic member which is interposed between a key top member (17) and the opposed switch members (12). A springback force is obtained by the elastic member to restore the key top member (17) and the link member (14) to their original positions. Thus, the number of resin components is reduced. A push button switch reasonable in cost and low or short in size is provided.

A method is provided for manufacturing an electronically functional structural component adapted to integrate a plurality of electronic functions into a laminate cover, layer, and/or laminate component, for protecting, supporting, and/or forming a complete electronic device (such as a multimedia device). The method includes laminating a plurality of structural and/or protective layers interspersed with electronically functional layers or electronic components in communication with the multimedia device to form a supportive and electronically functional layer, cover, protective layer, and/or electronic device. Thus, the manufacturing methods provided allow for the cost-effective addition of thin and lightweight functional, protective, and/or decorative layers to a multimedia device or other electronic device at a sales location or other customization location.

Le dispositif interrupteur selon l'invention fait intervenir un circuit imprimé (2) portant au moins deux plages conductrices (6, 7) coopérant avec une capsule (10) réalisée en un matériau électriquement conducteur et élastiquement déformable, cette capsule (10) étant maintenue en contact électrique, par sa périphérie avec la première plage conductrice (7) et s'étendant, au repos, au-dessus de la seconde plage conductrice (6). La plage conductrice (6) présente une forme annulaire et borde une cavité centrale (5) réalisée dans le circuit imprimé. Cet interrupteur produit un effet tactile sans avoir à utiliser de moyens particuliers dans la liaison capsule/poussoir.
摘要:
Mobile phones are in a trend of having thinner configuration due to emphasis on the design. Thus, in order to meet this demand, the present invention aims to thin the key sheet portion as much as possible. The present invention provides a thin key sheet 1 comprising a key top 2 made of a metal or a resin having on the front surface or the back surface indications such as letters, symbols, graphics or the like indicating the functions of keys, a key pad 3 made of a material having rubber elasticity such as a silicone rubber or various elastomers for supporting/fixing the key top, an EL element 8 formed on the back surface of the key top by means of printing, and a printed circuit board 5 on which a switch element is provided at its surface for turning ON/OFF of an electric circuit by the pressing of the key top 2 and on which a circuit pattern involved therewith is formed.

A pushbutton switch (1) includes a fixed contact portion (3) provided on a substrate (2) and an elastically deformable movable contact portion (4) provided in opposition to a surface of the fixed contact portion, the movable contact portion being configured as a dome-like portion forming a greater gap relative to the surface of the fixed contact portion at a center portion of the surface than at a peripheral portion of the surface. The fixed contact portion (3) includes, at a center portion on the surface thereof, a surface-devoid portion (5) forming a contact edge (30) in cooperation with the surface, and the movable contact portion (4) includes a projection (6) projecting toward the surface-devoid portion of the fixed contact portion. When a press force is applied to the movable contact portion (4), the movable contact portion is elastically deformed against resilience thereof toward the contact edge (30) to come into contact with the edge or an area adjacent thereto. When the press force is released, the movable contact portion (4) is elastically restored to move its projection (6) away from the contact edge (30) or the adjacent area.
