在电梯行业，轿箱内的操纵箱控制面板以及每层楼安装的外呼板上都会用到按键开关，该按键要求具有高可靠性、抗干扰、长寿命和易用美观的特点。目前大部分使用的都是机械式按键。
 
传统机械式按键通过微动开关和机械结构来实现按键功能，当按键被按下时触发微动开关输出信号给主板，当按键被释放时通过内部弹簧和机械机构实现回弹。传统机械式按键其成本很大一部分是花在模具上，所以如果要更改按键外观，比如外观形状（圆形，方形或者长条形）尺寸大小，按键附加功能，机械式按键就力不从心</description><dc:language>zh-CN</dc:language><generator>Telligent Community 13</generator><item><title>回复:电容触摸按键在电梯行业的创新应用</title><link>https://e2echina.ti.com/blogs_/b/the_process/posts/52813</link><pubDate>Wed, 02 May 2018 02:30:03 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:30c50a27-8ab4-4e6a-9ac3-ea46e413c8d0</guid><dc:creator>Butterfly</dc:creator><slash:comments>0</slash:comments><description>&lt;p&gt;TI &amp;nbsp;电容触摸芯片带手套也可以按，这是和别家电容触摸不一样的地方，而且支持金属面板和防水设计&lt;/p&gt;
