AI overview
A relay is an electrical switch that uses a small electric current to control a much larger electric current, allowing a low-power signal to turn high-power devices on or off. Relays are important because they enable safe and efficient control of powerful equipment from a distance, and they're used in everything from cars to industrial machinery.

继电器（Relay），也稱電驛，是一种电子控制器件，它具有控制系统（又称输入回路）和被控制系统（又称输出回路），通常应用于自动控制电路中，它实际上是用较小的电流去控制较大电流的一种“自动开关”。故在电路中起着自动调节、安全保护、转换电路等作用。
