Document Type and Number:
WIPO Patent Application WO/2018/014211
Kind Code:
A1
Abstract:
A backlight membrane switch, comprising a backlight board (1), a lower circuit board (2), a separator layer (3), an upper circuit board (4), and a button (5), the backlight board (1) being located at a lower part of the lower circuit board (2), the separator layer (3) being located between the lower circuit board (2) and the upper circuit board (4), the upper circuit board (4) being located at an upper part of the separator layer (3), the lower circuit board (2) being located at a lower part of the separator layer (3), the lower circuit board (2) being disposed with a first light guide hole (21) thereon, the separator layer (3) being disposed with a through hole (31) thereon, the upper circuit board (4) being disposed with a second light guide hole (41) thereon, a lower part of the button (5) being disposed with a third light guide hole (51), the button (5) being disposed with a conical reflecting mirror (52) and an inclined reflecting mirror (53) thereon, and the front of the button (5) being disposed with a transparent ring (54); light from the backlight board (1), after passing through the first light guide hole (21), the through hole (31), the second light guide hole (41), and the third light guide hole (51), being reflected by the conical reflecting mirror (52) and the inclined reflecting mirror (53), and then being emitted through the transparent ring (54). The light transmitted from the backlight board (1) being reflected by the conical reflecting mirror (52) and the inclined reflecting mirror (53) achieves a better backlighting effect.
