Relays are electromechanical devices that utilize an electromagnet to switch an electrical path. The basic design of a relay comprises a coil, armature, contacts, and a spring mechanism. When current flows through the coil, read more it creates a magnetic field which pulls the armature, causing the contacts to connect. This action allows for the co
