Electromechanical relays are devices that are used to switch electrical circuits on and off. They work by using an electromagnet to pull a contact arm towards the coil, which in turn opens or closes the circuit. These relays are commonly used in a wide range of applications, including industrial machinery, power distribution systems, and automotive electronics. They are reliable, durable and can handle high voltage and current levels. Electromechanical relays are also cost-effective and available in a variety of sizes and configurations to suit different needs.
