What is the function of a car relay?
1 Answers
Here is an introduction to the function of automotive relays: 1. Similar to general relays, relays in the electrical automation industry serve as 'switches,' meaning they act as an intermediate link that controls the on/off state of one circuit to regulate the next. Therefore, the role of a car relay is to control the magnitude and on/off state of the current. 2. The function of a relay is to use a switch to control the relay coil, which then causes the relay's working contacts to close or open. One end of the contact is connected to the main circuit current, and the other end is connected to the device to be controlled, enabling small currents to control large currents. This prevents the switch from being damaged by high currents and protects both the circuit and the switch.
