Introduction to DC 12V Relay
A DC 12V relay is an electrically - operated switch that uses a relatively low - power DC 12V signal to control a high - power 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 electromagnet generates a magnetic field, which attracts the armature and changes the state of the contacts. This allows the relay to isolate the control circuit from the power circuit, providing safety and flexibility in various electrical and electronic systems. DC 12V relays are widely used in automotive electronics, industrial control, home appliances, and telecommunications due to their compact size, high reliability, and easy control.
