definition of relay switch - EAS
Ảnh:scioly.orgElectromagnetic switch;A relay is an electromagnetic switch; hence, its heart is the electromagnet, which is powered by a small current that acts as a lever or as the switch itself. This makes it possible to allow relatively small electric currents to leverage and control much larger electrical currents.www.techopedia.com/definition/10318/relay- Mọi người cũng hỏi

A relay is an electrically operated or electromechanical switch composed of an electromagnet, an armature, a spring and a set of electrical contacts. The electromagnetic switch is operated by a small electric current that turns a larger current on or off by either releasing or retracting the armature contact, thereby cutting or completing the circuit.
