This is SONGLE RELAY. A relay allows a low-power electrical signal, such as from a microcontroller or sensor, to control a much larger current or voltage, such as required to drive a motor or light bulb. This allows a small electronic device to control a much larger one, or to isolate the low-power circuit from the high-power one. Relays are used in a wide range of applications, including automotive systems, HVAC systems, and computer power supplies.
