Relays
A relay is used to control a high-current circuit with a low-current signal, as in the starter solenoid of your motor. They are a simple electromechanical switch made up of an electromagnet and a set of contacts. They can be broken down into 2 circuits (A control circuit and a load circuit). The control circuit is the side with the coil and the load circuit is the side with the switch. When a current flows through the coil, the resulting magnetic field attracts an armature that is mechanically linked to a moving contact. The movement either makes or breaks a connection with a fixed contact.
