与将多个电流信号切换至单台安培表不同，将一个电流源切换至多个负载通常不需要任何时候到维持电流通路的连续性。
Unlike switching current signals to an ammeter, switching a current source to multiple loads usually does not require maintaining the current path at all times.
该电流源具有精度高、结构简单、工作稳定、操作方便、成本低廉、带负载能力强等优点。
It has advantages on high precision, simple construction, performance stable, easy operation, low cost and loaded capability.
