NC Contact and Contact NO Relay

This video explains how the contacts on the relay work, namely NC contacts and no contacts. When the relay is in normal condition the contact from pin 1 to pin 4 and from pin 8 to pin 5 is NC (Normally Close) or the contact is connected and pin 1 to pin 3 and pin 8 to pin 6 contact NO (Normally Open) or in disconnected state. When the relay coil gets voltage, the relay will work and change the contact from pin 1 to pin 3 and from pin 8 to pin 6 to be closed or connected while pin 1 to pin 4 and pin 8 to pin 5 become open or disconnected. Watch the video... #relay #contactno #contactnc
