text: If the set of contacts was closed when the relay was de-energized, then the movement opens the contacts and breaks the connection, and vice versa if the contacts were open.
text: The contacts of it are either opened or closed which is done simultaneously.
text: By introducing both NO and NC contacts, or more commonly, changeover contacts, on the same relay, it then becomes possible to guarantee that if any NC contact is closed, all NO contacts are open, and conversely, if any NO contact is closed, all NC contacts are open.
text: The normally open contact will be open when the no power is applied to the coil.
text: The contacts are open when the energizing force (magnet or relay solenoid) is not present.
text: The main difference between a regular relay and a time delay relay is that in case of a normal relay, the contacts are close or open immediately when the coil is energized or de-energized while in case of time delay relay, the contacts are close or open only after the preset time interval.

text: All of the contacts that were closed, now open and all of the contacts that were open, now close.
text: A special concern is that contacts must be able to quench the electrical arc that forms as the contacts are opened.
text: Also, due to the larger loads there is more arcing as the contacts are opened.
text: When the contacts are closed, an electric current flows through the contacts, and when the contacts are opened, the current stops.
text: When current flows through the coil then the contact is opened as you can see in the animation above.
text: When the contacts of a switch are opened, an arc is produced in the air between the contacts.
