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。
For ex ample, hot switching is typically used where digital logic is involved, because devices may change state if the power is interrupted even for a brief instant.
例如，当涉及到数字逻辑时，由于即使瞬间中断信号，器件的状态也可能会发生变化，所以通常就需要采用热交换。
Hot switching: When digital signals are being switched, they may change state with any length of power interruption. Using hot switching prevents digital state changes.
热切换：当数字信号被切换时，任何时间长度的电源中断都会使其改变状态。采用热切换可防止数字状态变化。
