What Does NC Stand For?

NC stands for Normally Closed

NC, or Normally Closed, refers to a type of electrical switch or relay configuration in which the contacts remain closed when the device is in its unpowered state. This arrangement allows current to flow through the circuit until the switch is activated, opening the contacts and interrupting the current. Normally Closed devices are commonly used in safety and control applications, where maintaining a circuit in an enabled state is crucial until a specific action is taken.
