Multiple Purpose Relay

Relays for Multiple Purposes

AutoZone carries multiple purpose relays from ACDelco, Duralast and other reliable electrical parts brands. A multiple purpose relay has a broad range of applications. You should check the voltage rating, terminal count and design before purchasing a part. The height and width of this component also affect the fit. We make it easy to find the best multi purpose relays for cars and trucks in store and online.

Select the Right Relay

An automotive relay makes it possible for a low amperage circuit to switch a circuit with higher amperage on and off. Directly connecting a high amperage electrical system to a low amperage switch could exceed the rating of the switch and raise the risk of electrical fire or part damage. It is also possible to connect relays so that one output switches on multiple components at the same time.

Check to see whether the relay you are considering are Single-Pole Single-Throw or Single-Pole Double-Throw designs. A close circuit design has a coil and load circuit paired with a switch. The coil creates a magnetic field when it receives power to close or open the switch. It is important to select a relay with the right design for controlling particular automotive systems.

Save on Electrical Components

Electrical components such as relays are not the most expensive parts, but the cost of replacing multiple relays can add up. AutoZone has the lowest prices on multi purpose relays and components designed to work with particular automotive systems. In addition to everyday low prices when you shop in store, you can also save on delivery costs with fast and free next day delivery on selected items and in store pick up options.

Replacement Exterior Relays

We also make it easy to find replacement exterior relays for specialized applications in heated mirrors, horns, headlights, lights and other critical electrical components. You can also order a relay kit and assembly that contains everything necessary to make electrical wiring jobs easier. Specialized relays may require replacement with vehicle specific parts. You may be able to use a multiple purpose relay for a range of applications on a variety of car and truck makes and models.

Depending on the use, multiple purpose relays may be vehicle specific. You can find out whether this is the case by entering the make, model and year of your vehicle into our search tool and reviewing the notes on different relay designs. You can also provide this information to an associate in store to make sure that you choose a relay that performs reliably, which can reduce the risk of electrical malfunction. If you need to quickly replace a relay, search for multi purpose relays near me to locate compatible parts at the nearest AutoZone location.
