为了研究开关电接点的机械抖动特性和测量机械抖动情况，研制了机械抖动测量系统。论述了测量系统的硬件设计和软件设计，给出了测量系统的电路原理图，以及关键程序源代码。对轻触按钮开关、复式按钮开关、单刀双掷开关的机械抖动次数进行了测量，测量结果表明：机械抖动次数是随机数，为0～625；对于复式按钮开关而言，前沿抖动次数明显小于后沿抖动次数。人们在操作按钮开关时，要迅速果断且用力要恰当，这样有助于减小机械抖动次数。

In order to study mechanical dithering feature of switch electric contact and measure the number of mechanical dither , we designed the measuring system of the mechanical dither .The article relates the design of hardware and software of the measuring system .Its circuit diagram as well as the key program source code has been put forward .The mechanical dithering number of nudging button , compound button SDPT switch has been measured , which shows that:the number of mechanical dither is a random digit in 0 to 625;for compound but-ton, front edge dithering number is less than back edge dithering number obviously .When pressing the button switch, people need to operate it quickly and decisively and force it appropriately , which helps to reduce the mechanical dithering number .
