3. Structure and Components
Housing: Typically made of insulating plastic or metal, protecting internal components from external environmental damage and interference.
Coil: Located at the core of the relay, it generates a magnetic field to drive the iron core when energized.
Iron Core and Armature: When the coil is powered on, the iron core attracts the armature to move, realizing the closing or opening of contacts.
Contact System: Consists of Normally Open (NO) and Normally Closed (NC) contacts, which control circuit on-off via mechanical connections.
Spring: Provides a reset function. When the coil is de-energized, the spring returns the armature to its original position, switching the contacts accordingly.
