Introduction to DC 12V Relay
A DC 12V relay is an electromagnetic switch that uses a low - voltage DC signal (12 volts in this case) to control a higher - voltage or higher - current circuit. It consists of an electromagnet, an armature, contacts, and a spring. When a 12V DC voltage is applied to the coil of the relay, the magnetic field generated by the electromagnet attracts the armature, which in turn closes or opens the contacts, allowing or interrupting the flow of current in the controlled circuit. DC 12V relays are widely used in various industries such as automotive, industrial automation, home appliances, and telecommunications due to their ability to provide electrical isolation and control high - power circuits with low - power signals.
