What is a nc contact?
An N.C. contact is 'Normally closed'. This applies to relays (electronic switches). You can use either a normally closed contact or a normally open contact to do what you need, provided the relay has both and depending on your situation. Here's a recent example of mine: A building's fire alarm is wired to the HVAC system to shut down ventilation in case of a fire. In this case we want the HVAC to have power normally but remove power (with the relay) during a fire alarm. We would connect the HVAC power to the relay's N.C. (normally closed) contacts, because they are exactly that: normally closed. This would allow the HVAC to function. When power is applied to the relay, it would switch contacts, disconnecting power to the HVAC. An important note is that contacts and other electrical connections that can change condition (such as a relay) are described in a de-energized state. Thus, the N.C. contacts are normally closed, while the power to the relay is off. Likewise, a N.O. contact is open with relay de-energized but will close upon supplying power to the relay.

Please resubmit your question as it is not quite clear as to your question/understanding. Thank you.
North Carolina the state under Virginia which is the best state inthe world yes it is because I live in Rockingham, NC and it issplendid here.
It is in the Mideastern area of America near South Carolina.
From where? lol...
NO is normally open contact, NC is a normally closed contact.
In North Carolina, small claims court is a division of district court. The phone number for Alexander County District Court is 828-632-2215. For additional contact information… and North Carolina court resources, see the related link.
What if your ex N devalued you a year ago now he is NC but sometimes he show himself to you sneaky online will he contact you ever?
Yes, N's often go back to earlier sources of N supply to see if they can squeeze some more life support out of them. Try to maintain NC or you'll be back to square 1.

When a NC and NO contacts are not working the NC will not open and the NO will not close.
Normally open and normally closed contacts are used in controls circuitry. They serve many functions.
When do ex narcissists respects you or fear you knowing you know some dirt about them would they re contact you being now NC?
Narcissists so overestimate themselves they wouldn't really believe your bit of dirt on them would matter much having survived with so much more dirt there ought to be on them…. That covers 99% of things you are likely to come up with, so save yourself the embarrassment and stay no contact. If by any chance you've hit the 1% of something a Narcissist believes that bit of dirt could have actually serious ramifications and thinks it will stick and you'd do this- ask yourself these crucial questions before you for warn your threat: Is it something law enforcement is already working on a definite arrest and you are a clearly protected witness? Are you a high scoring psychopath according to Hare's inventory ? If your answer is No to the second question, without Yes to the second one, ask this final question. How crazy are you and how much would you like to see your house burnt down , pets or your relatives or yourself maimed and more forms of suffering? A Narcissist would only be restrained in repaying with extreme vengence if either these things applied: Being a high scoring psychopath as they are recognised by Narcissists as even better at fighting back. Or alternatively strong law enforcement surrounding him and you'd still need very strong law abiding persons ready to witness , security cameras, strong new locks with the Narcissist aware that you have all that in place. Narcissists are best dumped, with no contact kept and proper use of the law and witnesses if they try to come back. They can be so ruthless and short sighted that if you enrage them in enough they really don't care or believe the usual constraints matter.
When the contacts are Normally Closed (NC) the stop button is "in series" with the supply voltage. By activating the STOP function the contacts open interrupting the flow of c…urrent.

NO stands for Normally Open and NC is Normally Closed. It references a switching application. It is the base state of the switch. So if the load is connected to the NC termina…l it will usually be energized and when the switching device is activated the circuit will open and the load will be de-energized. The NO terminal would have the load de-energized until the switch was activated and then it would be energized.

yes we can implement the 'NOT' gate operation by using a relay. At first we have to know the logic of NOT gate. when i/p is high it will give o/p high and vice versa …so for implementing this opertion via relay we have to use the relay contact "NC".i.e normally closed then only it is possible. By considering that we are using the NC contact of the relay then when we energise the coil of the relay the NC contact will change over to NO so it is similar to logic opertion i/p high --- o/p low Ex: the microwave oven won't get energised till the door is closed .
