1. Relay Basics

A relay is an electromechanical switch that opens or closes contacts when energized by an electrical signal. It consists of: Coil: The electromagnet that generates a magnetic field when energized. Armature: A movable part that is attracted or repelled by the magnetic field to open or close contacts. Contacts: The switching elements that either make or break the circuit depending on the position of the armature. Spring: Used to return the armature to its default position when the coil is de-energized. 2. Relay Assembly Process Coil Winding: The coil is wound with insulated wire, typically copper or aluminum, and is a critical part of the relay. Proper winding techniques ensure the coil has the correct number of turns, resistance, and inductance for efficient operation.
