ABSTRACT:
A movable contact element including a lower sheet having a bottom surface, to which a substantially dome-shaped movable contact is bonded, is provided. The movable contact is made of a conductive thin metal plate, and an upper sheet with a light reflection property is disposed above the lower sheet. A space is formed between the lower sheet and the upper sheet, and a light transmitting portion is provided at the upper sheet. Light of a light emitting element from the side surface of the sheet propagates through the space between the upper sheet and the lower sheet with a light reflection property, while being reflected in a vertical direction, and lighting is performed through the light transmitting portions. Such a structure can perform lighting without unevenness by using one or two light emitting elements.
