机械式旋转编码开关广泛应用在很多领域，大部分应用中是通过单片机对编码开关进行信号检测来判断编码开关的旋转方向和次数，但是在编码开关旋转过程中，往往会产生信号抖动，引起信号检测出错，本文分析了编码开关信号抖动对信号检测的影响，并提出了一种软件抗抖动的方法，可以有效避免编码开关信号抖动的影响。

Mechanical rotary encoder switches are widely used in many fields; and most of which are used for con-ducting signal detection through microcontroller to determine the rotary direction and times of encoder switch. But during the rotation of encoder switch, it is prone to generate signal jitter which will cause error of signal detection. This paper analyzes how the signal jitter of encoder switch may affect the signal detection, and brings forward an anti-jitter method of software to effectively avoid the impact of signal jitter of encoder switch.
