How does an automotive relay work?
In the most simple terms an automotive relay is an electronically operated switch. The type most commonly used in the automotive industry is an electro-mechanically operated switch. They employ an electromagnet device to mechanically manoeuvre a switch to make or break an electrical circuit.
How does a relay work diagram?
Relays control one electrical circuit by opening and closing contacts in another circuit. As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized. In either case, applying electrical current to the contacts will change their state.
What is the main function of relay?
Relays are the switches which aim at closing and opening the circuits electronically as well as electromechanically. It controls the opening and closing of the circuit contacts of an electronic circuit. When the relay contact is open (NO), the relay isn’t energize with the open contact.
What is automotive 12V relay?
12 Volt Automotive Relays. Automotive relays are for use in 12 volt electrical systems. Relays are used when you need to switch higher currents than a switch can handle, or when you want to isolate an electrical circuit. Our relays have either 5 contacts or 4 contacts. Relays with 5 contacts are called Changeover Relays,…
What is automotive relay?
An Automotive Relay is used to pull signal from a source (Headlight connector) that triggers power to be drawn from the battery. There are two sets of cables meant to provide power to an HID ballast.
What is a relay on a car?
A car relay is a electro-magnetic switch that uses a small amount of current to control a larger amount of current.
What does a car relay do?
A car relay is a particular kind of remote-control switch. It is magnetically operated and is used to control electrical circuits from a distant point.
