What is the Subaru Forester ST relay?
1 Answers
Subaru Forester ST is the headlight washer relay. Introduction to relays: Relay, also known as an electrical relay, is an electronic control device that consists of a control system (also known as the input circuit) and a controlled system (also known as the output circuit). It is commonly used in automatic control circuits, essentially functioning as an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays roles in automatic regulation, safety protection, and circuit switching within circuits. Main functions of relays: Relays are automatic switching components with isolation functions, widely used in remote control, telemetry, communication, automatic control, mechatronics, and power electronic equipment, making them one of the most important control components. Headlight relay system: A relay typically consists of several main contacts plus two coil contacts, similar to a contactor. The main contacts are connected to the controlled system, while the coil contacts are connected to the control system.
