Relay is a group of people or animals engaged in a task or activities for a period of time and then replaced by a similiar group.The basic for all the relays are same. Take a look at 4- pin relay show. There are two colors shown. The green color represents the control circuit and the red color shows the load circuit.A  switch is connected to the load circuit. A small control coil is connected onto the control circuit.
HOPE THIS MAKES U UNDERSTAND PROPERLY WITH AN IMAGE OF RELAY OPERATION!!!!!!!!!!!!!!!!!!!!
