A relay is an electrically operated switch . Many relays use an electromagnet to mechanically operate a switch . Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits) , or where several circuits must be controlled by one signal . The Advantages of this type of relay are : can be used to remove harmonics, high switching capability, without sparking off . Relays were used extensively in telephone exchanges and early computers to perform logical operations . Bornika is the exclusive representative of Relpol & Enerdis company, in purchasing, sales, consulting and distribution of industrial equipment and various auxiliary relays such as Subminiature signal relays , Miniature relays , Industrial relays , Interface relays , Installation relays , Time relay , Programmable relays .
