Abstract:
A touch panel includes first and second substrates, and first insulating layer disposed therebetween. The first substrate has, on its bottom surface, a first conductive layer having opposing first and second sides; a first electrode along the first side; and a second electrode along the second side. The second substrate has, on its top surface, a second conductive layer facing the first conductive layer with a predetermined space and having third and fourth sides orthogonal to the first and second sides: a third electrode along the third side; and a fourth electrode along the fourth side. The first insulating layer is frame-like and coats at least part of the first and second electrodes. The first and second electrodes and the first insulating layer together form a decoration part having a color tone to prevent the third and fourth electrodes from being visible when viewed from the first substrate side.
Abstract:
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.
Abstract:
A light shielding part includes a slit provided between a first light guide body and a second light guide body, and an attenuation part which has unevenness formed by print and is additionally provided near end sides of the first light guide body and the second light guide body. The light shielding part can prevent light from being transmitted between the first light guide body and the second light guide body. With this configuration, when illumination parts of the first and second light guide bodies are illuminated, it is possible to illuminate the illumination parts of the first and second light guide bodies at different timings without the illumination part of one light guide body being illuminated with light leaked from the other light guide body.

Abstract:
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.

Abstract:
The movable contact unit with a light-guiding function has the following structure. An uneven section is formed in a section that is to be lighted on the lower surface of a TPU-made base sheet. A film with a refractive index of light lower than that of the base sheet is disposed beneath the lower surface of the base sheet in a manner that the uneven section is embedded in the film. Besides, an adhesive layer is disposed beneath the film so as to hold a movable contact. The movable contact unit structured above is effectively employed for a lighted panel switch capable of reducing loss in amount of light and providing the section that is to be lighted with required illuminance.

Abstract:
A movable contact unit includes a base sheet made of polyurethane resin, a domed movable contact made of thin metal sheet, and a pushing protrusion. The movable contact is held on a first face side of the base sheet. The pushing protrusion is formed on a second face of the base sheet at a place corresponding to a domed top of the movable contact.
Abstract:
A movable contact to be used for various electronic equipment is provided. An electroluminance layer (12) is formed on a main surface (11a) of a substrate (11), and the substrate (11) and the electroluminance layer (12) constitute an electro-luminance element (13). A diaphragm (15) in essentially a dome-like shape is adhered to a specified spot of main surface (12a) of the electroluminance layer (12), constituting the movable contact (16) which includes the electroluminance element (13) and the diaphragm (15). The electroluminance element (13) is molded into essentially a dome-like shape along the shape of the diaphragm (15). A spacer for placing the diaphragm (15) is eliminated, so an inexpensive movable contact in a simple structure and a production method thereof is provided.
