Introduction to 12VDC Relay
A 12VDC relay is an electromagnetic switch that uses a low - voltage 12 - volt direct - current signal to control a high - power circuit. It consists of an electromagnet, an armature, contacts, and a spring. When a 12VDC power is applied to the coil of the relay, the electromagnet generates a magnetic field, which attracts the armature and closes or opens the contacts, thereby controlling the flow of current in the controlled circuit. 12VDC relays are widely used in various fields such as automotive electronics, industrial control, home appliances, and telecommunications due to their reliable performance, low power consumption, and small size.
