Lighted switch illuminator and its fabrication method

摘要

A lighted switch illuminator comprises an EL layer (26) diretly formed on a film click board (24) by stacking layers consisting of a transparent electrode layer (13), a light emitting layer (14), a dielectric layer (15), a rear electrode layer (16) an insulation layer (17). The EL layer is formed to exclude hollow convex portions (25) of the film click board (24). Upper contacts (20) and lower contacts (23) are formed on the film click board (24) and a printed board (21), respectively, such that they face each other. Depressing a key button pushes the corresponding hollow convex portion (25) so that the upper contact (20) and the lower contact (23) are brought into conduction, in which case a good click feeling is obtained because the EL layer (26) is not formed on the back of the hollow convex portions (25). <IMAGE>
