Electromagnet Activation: The electromagnet, when energized, generates a magnetic field. This magnetic field attracts the armature, a movable component within the relay, causing it to move and bridge the contacts.
Contact Closure: With the armature in place, the contacts come together, establishing a conductive path. This closure allows current to flow through the high-power circuit, enabling the connected device or system to operate.
Electromagnet De-energization: When the electromagnet is de-energized, the magnetic field collapses, releasing the armature. This releases the contacts, causing them to separate and break the conductive path.
Current Interruption: With the contacts open, the flow of current through the high-power circuit is interrupted, effectively turning off the connected device or system.

The operation of a wiring relay with switch, with its precise coordination of electromagnet activation, contact closure, and current interruption, forms the backbone of its ability to control high-power circuits efficiently and reliably.
