切换电流是指继电器在开路和闭合触点时能可靠处理的最大电流。
Switched current is the maximum current that can be handled reliably while opening and closing contacts.
这种电荷转移是由于触点的机械释放或闭合、“触点-线圈”电容以及信号和继电器驱动线路之间的寄生电容引起的。
This charge transfer is due to the mechanical release or closure of the contacts, the contact-to-coil capacitance, and the stray capacitance between signal and relay drive lines.
对于相对较大的继电器，为了确保触点良好闭合，也可能必须采用热切换。
With relatively large relays, it is even possible that hot switching must be used to ensure good contact closure.
