回原来的位置，使动触点与原来的静触点（常闭触点）释放。这样吸合、释放，从而达到了在电路中的导通、切断的目的。对于继电器的“常开、常闭”触点，可以这样来区分：继电器线圈未通电时处于断开状态的静触点，称为“常开触点”；处于接通状态的静触点称为“常闭触点”。

2、电路原理

继电器是一种当输入量变化到某一定值时，其触头（或电路）即接通 或分断交直流小容量控制回路。

由 磁铁保持释放状态，加上工作电压后，电磁感应使衔铁与 磁铁产生吸引和排斥力矩，产生向下的运动， 达到吸合状态。

3、 晶体管驱动驱动电路

当晶体管用来驱动继电器时，推荐用NPN三极管。具体电路如下：

当输入高电平时，晶体管T1饱和导通，继电器线圈通电，触点吸合。

当输入低电平时，晶体管T1截止，继电器线圈断电，触点断开。

电路中各元器件的作用：晶体管T1为控制开关；电阻R1主要起限流作用，降低晶体管T1功耗；电阻R2使晶体管T1可靠截止；二极管D1反向续流，为三极管由导通转向关断时为继电器线圈中的提供泄放通路，并将其电压箝位在+12V上。
