7 | **简介** 8 | 9 | > 单个机械按键的操作，通常分为两种模式，即长按和短按。其中，长按又可分为定时长按与计时长按，定时长按即按下按键并保持按下状态达到设定时间后触发事件，且只触发一次，常用于设备复位。而计时长按则为在保持按下状态的情况下，达到设定时间（长度）值便触发一次事件，直到松开按键为止，此种方式常用于长按自动累加调整数值。短按则又可以分为单次点击和连续多次点击两种，单次点击就是按一下按键然后就松开，常用于普通的按键控制等；多次点击就是在设定的时间内连续按下、松开、再按下、再松开，来回多次，常用于一些设备的快速控制，如静电放电枪的扳机（开关），在停止状态下，扣动一次，则会切换电压极性，在停止状态下，连续扣动2次则会增加实验电压值，连续扣动3次则会减少实验电压值，连续扣动4次则会开始实验。
