Relays

A relay is an electrically operated switch that allows a low-power signal to control a higher-power circuit. Imagine it as a gatekeeper: when the low-power signal reaches it, the relay opens or closes the gate, allowing electricity to flow through a different path. This enables devices, like motors or lights, to be turned on or off safely without exposing the controlling circuit to high voltages. Relays are commonly used in various applications, from automotive systems to home appliances, providing efficient control and protection of electronic devices.
