A light-guide sheet includes a light transmissive film substrate, and luminescent protrusions formed at predetermined points on the substrate. At least one of the substrate and each of the luminescent protrusions is colored to a color tone that absorbs yellow light more than blue light. Alternatively, a reflective layer colored to a color tone that absorbs yellow light more than blue light is provided on at least one of the top and bottom faces of the substrate.

A movable contact unit includes a light-guide sheet, a cover sheet, a movable contact, and a light-transmissive light-guide portion. The light-guide sheet includes a film-shaped substrate, and a convex and concave luminescent portion provided on the substrate. The cover sheet faces the substrate. A dome-shaped resilient movable contact made of a thin metal sheet is attached to the cover sheet at a position corresponding to the luminescent portion. The light-guide portion is provided on the cover sheet at a position other than an area where the movable contact is disposed or on the light-guide sheet at a position other than an area where the light-guide portion is disposed. If the light-guide portion is provided on the light-guide sheet, the movable contact may be attached to the light-guide sheet without using the cover sheet.
摘要:
A light guide sheet and a movable contact element using the single sheet have a simple structure and can be variously illuminated. The light guide sheet includes irregular-shaped light emitting elements formed on a film-like base material; and light-transmissive, belt-shaped light guide parts each connecting a predetermined number of groups of the light emitting elements. In addition, dome-shaped movable contacts formed of a conductive sheet metal are arranged on the bottom surfaces of the light emitting elements. This structure allows the light emitting elements to emit light of different colors from each other or to emit light with a time difference by making the light guide parts introduce the light of the light-emitting devices corresponding thereto.

A light guide sheet and a movable contact element using the single sheet have a simple structure and can be variously illuminated. The light guide sheet includes irregular-shaped light extracting elements formed on a film-like base material; and light-transmissive, belt-shaped light guide parts each connecting a predetermined number of groups of the light extracting elements. In addition, dome-shaped movable contacts formed of a conductive sheet metal are arranged on the bottom surfaces of the light extracting elements.
摘要:
A light guide sheet guides light emitted from a light introducer. The light guide sheet includes a film-shaped substrate, a light emitting section formed on the substrate, and a belt-shaped light-blocking section. The light emitting section reflects or scatters light transmitting in the substrate to the outside. The light-blocking section is formed in the substrate by coloring a position of the substrate to a color. In the position, the light emitting section is not formed. The color absorbs the light which is emitted from the light introducer. The light emitting section can alternatively be composed of a plurality of projections and/or a plurality of recesses. Such a light-blocking section is formed in a position of the substrate where the projections and/or the recesses are not formed.
摘要:
A movable contact point made of a thin conductive metal sheet in an approximate dome shape is attached to the lower surface of a transparent base sheet, and the base sheet is provided at the upper or the lower surface with a fluorescent layer in the location above the movable contact point. Since, in the make-up, light can be made available for illumination in many colors other than that generated from a light emitting device, a movable contact element, as well as a switch formed using the contact element, that offers various illuminating modes can be implemented in a simple structure.

A movable contact assembly includes a light guiding sheet which is light transmittable, and a movable contact provided on the light guiding sheet. The light guiding sheet has a portion having the movable contact provided thereon and a portion having plural grooves provided therein. The grooves constitute a light inlet for introducing light into the light guiding sheet. This movable contact assembly can illuminate a switch preferably with a simple structure, providing the switch with an easily operation.
