OPERATION
- The magnetic field "pull" in the armature and close the NC contact to NO.
- When the current stop flowing, the armature return back to normal position.
- Current pass through coil, magnetic north & south pole are produced across the gap seperating the coil and armature, acting like electromagnet.
- Relay actuated whenever sufficient current intensity produced enough force to overcome spring tension.
