簡介:

A selection switch is an electrical switch that chooses a specific circuit or collection of circuits. In a three‑phase system, selector switches are used for both voltmeters and ammeters. The ammeter selector alternates between the three phase line currents, while the voltmeter selector can alternate between line‑line voltage or between line‑line and line‑neutral voltage.
