Familiarize Electronic Components Part X – Relay


A Relay is an electro mechanical switch used for driving heavy current loads in electronic circuits. Relay interface the electronic circuits with high voltage AC and there is complete galvanic separation between the two. When current passes through the relay coil, magnetic field develops which attracts a lever and changes the switch contacts. The contacts can be used to connect AC or DC loads which may then turn On / Off the load depending on the contact connections.
