In a relay, which component opens and closes the switching contacts?

Explanation:
The moving armature is the part that opens and closes the switching contacts. When the coil is energized, its magnetic field pulls the armature into position, which moves the contacts to establish or interrupt the electrical path. When the coil current is removed, a restoring force or spring returns the armature to its original position, reversing the contact state. The coil provides the magnetic force, but it’s the armature that physically moves the contacts to make or break the circuit.
