Description

technical field

[0001] The present invention relates to a movable contact body and a switch using the movable contact body. Background technique

[0002] In recent years, in various electronic devices, especially mobile terminal devices such as mobile phones, light-emitting diodes, EL elements, etc. The number of components for illuminating the operation portion is increasing. It is required that movable contact bodies and switches used in these devices can be variously illuminated at low cost.

[0003] Figure 7 It is a cross-sectional view of a conventional movable contact body 4 . The film-shaped light guide sheet 1 is both light-transmitting and flexible. A plurality of dot-shaped diffusion portions 1A are formed on the upper surface of the light guide sheet 1 . The light guide sheet 1 and the film-like cover sheet 2 are bonded together at predetermined locations on their outer peripheries with an adhesive.

[0004] Movable contact 3 is formed of a thin conductive m...
