动触点（moving contact），是指继电器(或功能电器)中执行机械运动的触点。
触点闭合后。动触点仍在旋转。
After the contacts are closed, the movable contact still rotates.
加上的电路方程序，可动触点的开口时，也可以得到的使用迭代与接触力的限制。
Coupled with circuit equations, the opening time of movable contact also can be obtained using iteration with the restriction of contact force.
研究了触点分离初速度(动触点与静触点刚刚分离时刻的动触点速度)对电弧能量的影响。
This paper emphasizes on the influences of arc energy by the contact breakaway initial velocity that is the velocity of moving contact at the time of moving contact and stationary contact breaking.
