该按键面板10、背光板20、遮光板30和电路板40依序上下平行贴合固接在一起，并使得透光区12、贯穿区31和红外单元一一对应，以使红外发射器42发射的红外线经贯穿区31、背光板20能投射在按键面板10，能投射在透光区12，以使红外接收器43能接收经反射的红外线。该背光光源50连接背光板，背光光源发出的光线能照射在背光板20以使按键11具有背光。
该控制器41连接背光光源50、红外发射器42和红外接收器43，以使得：1、控制背光光源50发出光线，光线照射在背光板20，背光板20能通过透光区12背光；2、控制红外发射器42发射红外线，红外线经贯穿区31、背光板20投射在按键面板10，投射在透光区12；3、根据红外接收器43接收的红外线强度判断是否有按键操作，具体为，①、当用户无按压时，红外接收器43接收的红外线只包括：a、外部光源通过透光区投射进来的红外线，及，b、背部板20光源中的红外线；②、当用户按压时，手指按压在按键11（包括透光区12），红外发射器42发射的红外线经手指反射回红外接收器43，红外接收器43接收的红外线包括：a、外部光源通过透光区投射进来的红外线，b、背部板20光源中的外红线，及，c、经手指反射回的红外线。

本实施例之中，该出水机构例如为出水龙头70，该按键装置A装设在出水龙头70上,用以控制出水。
在实际使用时，由于自然界有各种各种的光源（如：太阳光、日光灯等），这些光源都会影响红外接收器43的接收，参见图5，V1为无光源照射，V2为白炽灯照射，导致控制器41接收各种错误的信号，进而导致相应动作误判。为防止由于外部光源可能引发的误判，本发明采取以下技术方案（参见图6、图7）：
一、预处理步骤：（参见图6）
1.上电，置于无外部光源环境；
2. 红外发射器42发射时，读取红外接收器43接收值，记Vref；
3. 无外发射器42发射时，读取红外接收器43接收值，记Vno；
4.手指按下按钮时，读取红外接收器43接收值，记Vactive；
5.芯片PIC16F913计算Vno-Vactive差值，获得一参考值Verror；
6.重复上述步骤获得各个按钮电路的相应参数。
本实施例为5个按钮，需要获得5个按钮电路的相应参数。
步骤2中，红外接收器43接收的红外包括：红外发射器42发射红外光透过背光显示板20和面板10的一部分红外及背光光源50被反射给红外接收器43。
二、控制器判断是否有按钮操作步骤（以一个按钮为例）：
1.无红外线发射时，读取红外接收器43接收值，记Vmax；
2.比较Vmax>Vno；
3.否，环境光源强，说明无按键操作，CNT=0；
4.是，红外发射器42发射；
5.读取读取红外接收器43接收值，记Vrev；；
6.比较：Vref -Vrev＞＝Verror；
7．否，无按键操作，CNT=0；
8.是，CNT+1；转步骤1
9.当CNT＞＝N；
10.判断有按钮操作，执行该按钮所指示的动作。
步骤4中 红外发射器42发射每隔T时间红外发射器42发射,发射时间为Ta。
步骤9中的N为大于等于6的自然数，一般为6-20。
如图7所示，在T1时刻（其他光源环境接收信号），芯片PIC16F913在预处理的基础上，通过上述两次计算比较，能够识别环境光的影响，因此本方案能很好的处理图7中T1时刻（其他光源环境接收信号）的干扰，使本发明可以在任何光源下使用，而不会误操作。
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
