The reliability of an electrical system depends on its components. By using an automotive Relay for turning devices on and off, you can enhance the performance as well as reliability of your system. It is in fact an electro-mechanical switch which makes use of an electromagnet to attract a bunch of pins or contacts together.
Why Relays score over switches
You can get good quality relays for sale available with online portals, but you might think why you should go for relays instead of an ordinary switch. Here are some of the features of relays that make them more effective than switches.
· An Automotive Relay when appropriately wired will ensure that the shortest electrical path is achieved between the battery and the device which the relay controls. The arrangement, along with an appropriate gauge wire, guarantees that the voltage drop between the device and the battery is minimized. This in turn allows the device to maintain its peak performance level.
· Once you buy quality relays for sale, you are able to gain control over a plethora of devices with just a single switch. For instance, if you are driving a race car, you can easily opt for a master ignition switch. When you have only a single switch that you can turn off during an emergency, the whole process becomes safer and more convenient. Moreover, having many relays and a single switch in place of a large number of bulky switches, makes your system look cleaner.
· By making use of relays, you can have a fuse of the proper size for every device, and these fuses can be positioned nearer to the battery.
· If for controlling high output lighting and other aftermarket devices, the stock wiring of the vehicle and switches is used, you can avoid stress or overload of the OEM components by fitting an automotive relay. Go through premier online portals and buy relays for sale, which will be able to handle a considerably greater current load compared to a switch.
Different types of relays that you can buy
Before you connect devices to a relay, it is essential to understand the function and pin configuration of the relay. Many automotive relays for sale look alike, possess similar pin configuration and can even be plugged into identical socket, but the switching duties performed by them are completely different.
The single pole-double throw is the most common type of relay used in vehicles. In this relay, there are two fixed contacts, namely the Normally Open and Normally Closed, and a movable, common contact moves between them, as the relay is energized and turned off. Then there is the single pole-single throw relay, which has two internally connect Normally Open contacts along with a common contact. Connection between the contacts is established through activation of the switch.
