Why is an automotive relay different than a standard relay?
Automotive relays are designed for use on a vehicle’s power system. They have spade terminals for quick and easy connections and a large current handling capacity. Use of automotive relays is not exclusive to vehicles. You could use the relay in hobby or model applications that run on a DC 24V power supply.

What does single pole double throw (SPDT) mean?
A single pole double throw relay is used to alternate which circuit a signal or voltage is sent to. It has one terminal on one side of the switch, known as the common, and two on the other side called normally open (NO) and normally closed (NC). When the relay’s coil is not powered, the common connector will be connected to the NC connection. When the relay is powered, the common connector will be connected to the NO connection.

Why would I use a relay?
There are several advantages to using a relay. It is an ideal solution for switching a high current to a lower current - for example if you wanted to use a lower powered switch to control some powerful spotlights on your vehicle.
You may also want something to turn off when something else is on – for instance having a light switch off in a vehicle when the engine is running.
You could also use a relay to have something powered by one battery control something powered by another. If, for example, you have a radio in a car running off the car battery and an amplifier in the boot running off its own - you can use the relay to switch the amplifier on when the radio is switched on.
