Relay 12V is a type of electromagnetic switch used in a wide variety of electrical and electronic circuits. Its primary function is to control the flow of electricity through a circuit, allowing low-voltage signals to control high-voltage circuits safely and efficiently. Whether in automotive systems, industrial automation, or household appliances, a 12V relay is a crucial component in many devices. This article will explore the working principle, applications, and essential factors to consider when using a 12V relay.
What is a 12V Relay? A 12V relay is an electrical device that uses a 12V direct current (DC) to control the opening or closing of contacts within a circuit. It typically consists of a coil, a set of contacts, and a mechanical or electromagnetic actuator. When a 12V signal is applied to the coil, it generates a magnetic field that either closes or opens the contacts, allowing current to flow through a connected circuit. This action can control high-voltage or high-current devices that are otherwise unsuitable to be controlled directly by a low-voltage microcontroller or switch. How Does a 12V Relay Work?
