Abstract

The invention relates to an illumination element for a switch and a switch apparatus having the same. Illumination for part of a plurality of operation keys is implemented, illumination periods of part operation keys and illumination periods of other operation keys can be missed, and illumination colors of part operation keys and illumination colors of other operation keys can be changed. Light LED 2A, 2B and 2C which are incident on the lateral end surface of a flexible light guiding plate 6 illuminate the illumination elements for the switch at the each bottom of operation key 3A, 3B and 3C, the flexible light guiding plate 6 is composed of a plurality of intersected parts 6A, 6B and 6C, LED 2A, 2B and 2C are provided corresponding to each of the intersected parts, a light absorption unit composed of lighttight portion for absorbing LED light is provided at the boundary between adjacent intersected parts 6A and 6B, and between adjacent intersected parts 6A and 6C, such as slots 20, 21 separating the boundary portion and the lighttight paint coated on the inner wall of the slots.

Description

technical field [0001] The present invention relates to a switch lighting member including a light source and a flexible light guide plate capable of irradiating light from the light source on the bottom surface of a plurality of operation keys used in an input unit of a mobile phone, and a switch device having the switch lighting member. Background technique [0002] As such prior art, the disclosure of patent document 1 is known. In this prior art, the structure is that switch elements are provided on the substrate, a flexible light guide plate is arranged on these switch elements, and a light guide plate having the same size as the width of the flexible light guide plate is arranged on the side of the flexible light guide plate. The light source is configured with a keyboard with multiple operation keys on the flexible light guide plate. [0003] In this prior art, by operating the operation key, the switch is turned on by pressing the corresponding switch element via th...
