High impedances are being switched, so some of the same switching techniques used when switching low current (Section 5.3.1) and high impedance voltages (Section 5.2.3) are equally applicable here.

由于切换的是高阻抗，所以切换小电流(5.3.1部分)和高阻抗电压(5.2.3部分)时采用的技术也同样适用。

Shielding may be essential in a switching system if a mixture of low current, high voltage, and high frequency signals are present.

如果切换系统中会混合出现小电流、高电压和高频信号，屏蔽则非常关键。
