• Designed for operation on 24V automotive power
• Single pole normally open designWhy 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 running of a DC 24V power supply.
What does single pole normally open (SPNO) do?
A single pole normally open relay is used when you want an incoming current to close or complete a circuit. As the switching current is applied, the break in the circuit is closed and the device switches on. The relay has a single pole and a single throw.
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 controlling some powerful spotlights on your vehicle with a lower powered switch.
You can use a SPNO relay to cut power to an area when you don’t need the circuit working, either as a safety measure or to conserve power.
