Applications and benefits of automotive relays


1: Switch inge switching high current circuits:

The most common application of automotive relays is to switch high-current circuits using low-current circuits. This application comes into play, where the linear switch cannot handle the current required to switch to a high-current electrical system. For example, this scenario can be observed when operating a set of high-power operating lights. If the working lights are connected to the lighting when the headlights are active, they may exceed the capacity set by the existing loom. The car relay can resolve this issue.


2: Activate multiple circuits with a single switch.

A key advantage of using a relay is that it allows multiple circuits to be activated from a single switch. A single input in the electrical system can be used to activate and trigger multiple relays installed in the circuit. These relays can then complete/disconnect multiple circuits, thus performing multiple functions when giving an input signal. A simple real-world example of this multi-action switch from a single switch is the central locking system in the car - a button press that causes all door locks to be locked or unlocked. Simple, time-saving and efficient.

3: The execution of logical functions.

Although recent relays have been largely replaced by OEM electronic module designs, they can also be used for logical operations. Automatic relays can be used to perform simple and complex logical tasks such as point input and time control functions - time control operation and internal light time delay of the wiper blades. While manufacturers have largely turned to programmable logic for these tasks, relays offer a simple and inexpensive alternative. Like car enthusiasts may find it easier, cheaper, and more attractive, install ingress to operate a simple logic function.


4: Save money.

High-current circuit components are expensive. Low-current components are much cheaper. Using relays means that you can limit the installation of high-current circuits to critical parts of the system. Then I install the relay at the key point, and the rest of the circuit can be done with cheaper low-current elements. This helps reduce costs. Everyone is happy!
