Contact life is much longer when cold switching is used.
当采用冷切换时，触点的寿命要长许多。
Cold switching is defined as opening and closing the switch when no current is flowing.
冷切换是指在没有电流流通时开路或闭合开关。
Cold switching is desired to extend contact life. It can increase contact life by 10-1000 times over switching at maximum levels.
冷切换可以延长触点寿命，最大时可将触点寿命提高10 ~ 100倍。
As the specifications state, if cold switching is used instead of hot switching at maximum signal levels, contact life is extended from 105 closures to 108 closures.
作为技术指标，如果在最大信号电平下采用冷切换而非热切换，那么触点寿命将会从105次开关次数延长至108次开关次数。
In addition, this section discusses issues such as calculating uncertainties, techniques for minimizing switching time, and the use of cold vs. hot switching.
此外，本章还讨论计算不确定度、最小化开关时间的技术，以及冷切换和热切换的对比。
