On a control contact, what does N.O. stand for?

Explanation:
N.O. means Normally Open: in a control circuit, this contact is open when the actuator is not energized, so no current flows. Energizing the coil closes the contact, completing the circuit. This default-open behavior is used when you want a device to stay off until a control signal activates it. It’s distinct from Normally Closed, which is closed when not energized and opens when energized.
