• Spade terminals for quick and easy connection without the need for a relay base
• 30A switching capacity
• Designed for operation on standard 12V automotive power
• Single pole double throw design

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. They are widely used in hobby projects, since they are designed to operate on 12V power systems.

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. You may want to switch a high current to a lower current, for example if you had some powerful spotlights on your vehicle but wanted to use a lower powered switch to control them.
You may want to have something go off when something else is on – for instance having a light go off in a vehicle when the engine is running.
You may also want to have something powered by one battery control something powered by another. If you have a radio in a car running off the cars 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.
