A relay is an electrically operated switch. It consists of a control circuit and a load circuit. When a small electric current passes through the control circuit, it can cause the relay to close or open the contacts in the load circuit. This allows a relatively small electrical signal to control a much larger current or voltage in another circuit. Relays are widely used in various electrical and electronic systems. For example, in industrial control systems, they can be used to start or stop motors. In automotive electronics, relays are often used to control high power components such as headlights and horns. They play an important role in ensuring the normal operation and safety of electrical equipment.
