Illuminated keyboard switch |
摘要 |
A cup-shaped elastic member 2 forces push button 1 upwardly that has indication part 1A formed thereon. Light transmitting electrode layer 15B, light-emitting layer 15C, and back electrode layer 15E are sequentially formed on light transmitting sheet 15A to form EL element 15, and the EL element is disposed on the upper or lower face of membrane switch 6. This structure can provide an inexpensive illuminated keyboard switch that allows clear illumination of the push button and uses a smaller number of components.
