Release time is the opposite of actuation time. It is measured from the time power is removed from the coil until the contacts have settled, again including bounce.

释放时间与触动时间是相对应的。它衡量的是从线圈断开激励到触点达到稳定所需的时间，也包括回跳。

Although these are the fastest switching elements when actuation times are compared, the release, or turnoff time, is long.

尽管在比较激励时间时这类继电器是最快的切换元件，但释放或关断时间却比较长。
