1·If the switched current is too high, the resulting temperature increase and contact arcing will degrade the relay and shorten the contact life.

如果切换电流太高，造成的温度升高和接触电弧将会劣化继电器并缩短接触寿命。

2·The region of motion of the first non-stationary contact between the first position and the second position includes an arcing region.

第一非静止接点在第一位置和第二位置之间的运动的区域包括一个燃弧区域。
