The 428 relay is an electrical relay used in various automotive and industrial applications, primarily for controlling high-current circuits. It typically features four terminals: two for the input coil and two for the output contacts. When voltage is applied to the coil, the relay activates, allowing current to flow through the output contacts, thus powering devices such as lights or motors. Its compact size and reliability make it a popular choice in vehicle wiring harnesses and control systems.
