    • PURPOSE: A key sheet module is provided to achieve improved key pad illumination efficiency on a one-sided printed circuit board by using a thin conductive film jumper for optimizing arrangement of light emitting diodes or electric elements. CONSTITUTION: A key sheet module(1) comprises a one-sided printed circuit board(2) having a one side on which a plurality of wiring patterns(4) are formed; contact switches(3) arranged on the one-sided printed circuit board; light emitting diodes(5) for key pad illumination; and a switch fixing sheet(9) for covering upper surfaces of the contact switches. An insulating layer is formed between predetermined wiring patterns spaced apart from each other. A conductive film jumper is formed over the insulating layer such that the spaced wiring patterns are connected with each other in a three-dimensional way.

    • A key sheet module is provided to dispose an LED or an electric device in an optimum location by using a thin conductive film jumper, thereby significantly improving lighting efficiency of the keypad lighting in one-sided circuit board. Between predetermined spaced line patterns(4) of plural line patterns, an insulating layer is formed. On the insulating layer, a conductive film jumper(18) is formed to stereoscopically connect the spaced line patterns as crossing each other. A white spacer(8) is a reflection plate and has an LED(Light Emitting Diode)(5) electrically connected with the line pattern and a mount hole(8a) for exposing a contact switch(3). Electric devices(6) electrically connected to the line patterns are arrange in left and right sides of a print line substrate so as not to block irradiation light from the LED for irradiating light to the contact switch. The white spacer is arranged within the electric devices arranged in both sides.
    • 提供了一种按键板模块,通过使用薄导电膜跳线将LED或电子设备配置在最佳位置,从而显着提高了单面电路板中键盘照明的照明效率。 在多个线图案的预定间隔线图案(4)之间,形成绝缘层。 在绝缘层上,形成导电膜跳线(18),以便彼此交叉地立即连接间隔开的线图形。 白色间隔物(8)是反射板,并且具有与线图形电连接的LED(发光二极管)(5)和用于使接触开关(3)露出的安装孔(8a)。 电连接到线图案的电子装置(6)布置在打印线基板的左侧和右侧,以便不阻挡来自用于向接触开关照射光的LED的照射光。 白色间隔物布置在布置在两侧的电气装置内。
