It consists of an electromagnet, an armature, a spring, and a set of contacts. When an electric current flows through the electromagnet, it creates a magnetic field that attracts the armature, causing the contacts to close or open. Relays are widely used in various electrical and electronic systems to control high &#8211; power circuits with low &#8211; power signals, isolate different parts of a circuit, and perform logical operations. They play a crucial role in industries such as automotive, telecommunications, power systems, and home appliances. <a href=\"https:\/\/www.ictransistors.com\/relay\/\">Relay<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.ictransistors.com\/uploads\/202320221\/small\/jinyushi-for-st-m28w320fst70za6-bga-100-new93d1697d-ed25-4ebb-831a-47ac6849c403.png\"><\/p>\n<h2>1. <a href=\"https:\/\/www.ictransistors.com\/\">GNS Components Limited<\/a><\/h2>\n<h3>Company Introduction<\/h3>\n<p>GNS Components Limited is a well &#8211; established electronic component supplier.
