12V Automotive Relay

At present, DC 12V relay is the most widely used product with the most models and types on the market.

It can be found in various devices such as headlights, wipers, seat position adjustment, fans, and electric machinery, etc.

How Does a 12V Automotive Relay Work?

A 12V automotive relay works by using an electromagnetic coil to activate a set of contacts that control the flow of electrical current. When a current flows through the coil, it creates a magnetic field that pulls the contacts together, allowing the current to flow through the circuit. When the current stops flowing through the coil, the magnetic field collapses, and the contacts spring back to their original position, breaking the circuit.
