[0002] An electromagnetic relay is an electrical component that operates by utilizing the attraction generated by current flowing through a coil between its core and armature. Electromagnetic relays generally consist of an iron core, coil, armature, contacts, and reeds. When a certain voltage is applied across the coil, a certain current flows through it, generating an electromagnetic effect. The electromagnetic force pulls the armature downward, overcoming the pull of the reeds. This causes the armature's moving and stationary contacts to close.
