您要查找的是不是：
- Cold switching, if feasible, will extend the relay life and make it possible to increase the allowable current. 如果可行，采用冷切换会延长继电器寿命，并有可能提高允许电流。
- Cold switching also eliminates arcing at the relay contacts and any RFI that might be caused by arcing. 冷切换还不会在继电器触点引起电弧，以及电弧引起的射频干扰（RFI）。
- Cold switching is always preferable to ensure maximum relay life. Cold switching involves turning the source current off (placing it on standby) before opening or closing a relay. 冷切换更适合确保继电器具有最长的寿命。冷切换需要在开路或闭合继电器之前将源电流关闭（将其置于待机状态）。
