RELAY


Relay and Configuration of Relay
     A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism. In electronic, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts.
