How Does a Relay Work? Explained With its Construction
How relays work. Here are two simple animations illustrating how relays use one circuit to switch on a second circuit. When power flows through the first circuit (1), it activates the electromagnet (brown), generating a magnetic field (blue) that attracts a contact (red) and activates the second circuit (2).
