Detail Miniatur Circuit Breaker OMRON
A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. 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.
