Truck relays are an essential accessory for the proper functioning of the vehicle. The power source in the car is only the battery which has a current of 12 V, 24 V or 48 V.

What is a car relay?

The relay is in the form of an electromagnetic device that allows the current to flow from the battery to the appropriate receiver - e.g. vehicle lighting. The most important feature of the part is enriching it with two operating circuits, which independently handle a small current, coming from a large current required (e.g. a starter) to start the engine, while there is a huge torque. This type of separation greatly simplifies the design and operation of the vehicle.

Relays for trucks - types

There are three categories of automotive relays according to the initial contact location:

• Relay with normally open contacts - an accessory most often used in vehicles, mainly in connection with the provision of proper lighting - eg dipped beam, high beam, fog lights, heated windows or a horn.

• Relay with normally closed contacts - the part that enables powering the alarm or immobilizer.

• Relay with change-over contacts - dedicated to mechanisms that allow you to move the windows or the central lock.
