What is an Automotive Relay?

abstract: Automotive relays of different sizes are found in every type of land or sea vehicle. They are often used to enable a low amperage circuit to switch a higher amperage circuit on or off. An example would be turning headlights on. Automotive relays also allow items to switch at the same time by using a single output, therefore allowing one to simultaneously open and/or close continuity on multiple items.

What is an Automotive Relay?

Automotive relays of different sizes are found in every type of land or sea vehicle. They are often used to enable a low amperage circuit to switch a higher amperage circuit on or off. An example would be turning headlights on. Automotive relays also allow items to switch at the same time by using a single output, therefore allowing one to simultaneously open and/or close continuity on multiple items.

Types of Automotive Relays

Choose from more than 200 automotive relays available from Future Electronics, offering one of the most comprehensive portfolios of SPST and SPDT automotive relays in the industry. Our parametric filters help refine your search results by Contact Arrangement, Contact Current, Coil Voltage and Termination Style. We offer a huge selection of Latching and Non Latching automotive relays in SPST, SPDT and DPDT combinations, with Coil Voltages from 5V to 120V (12V relays and 24V DC relays being the most common). The most common sizes for maximum contact current are 20 A and 30 A. We also carry automotive relays with maximum contact current as high as 300 A.

Future Electronics has a full selection of automotive relays from several manufacturers when looking for a relay in SPDT, SPST or DPDT combinations, PCB relays, a non latching automotive relay, a quick connect auto Relay, or for any circuit that might require an automotive relay. Simply choose from the automotive relay technical attributes below and your search results will quickly be narrowed to match your specific automotive relay application needs.

If you have a preferred brand (such as Tyco Electronics, formerly Potter and Brumfield, or Panasonic Electric Works, also known as PEWA (formerly Aromat) you can easily refine your automotive relay product search results by clicking your preferred automotive relay brand below.

Applications for Automotive Relays:

Automotive relays are found in several automobile applications including:

  • Car antennas
  • Power windows
  • Power seats
  • Car stereos
  • Horns
  • Door locks
  • Defoggers
  • Power sunroofs
  • Interior lighting
  • Intermittent wipers

Automotive Relay termination style is usually plug-in or quick-connect, and Future Electronics has a full selection of both versions, as well a wide choice of PCB mount automotive relays. Simply choose from the automotive relay technical attributes below and your search results will quickly be narrowed to match your specific automotive relay application needs.

Choosing the Right Automotive Relay:

When you are looking for the right automotive relays, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Coil Voltage (5V, 12V, 24 V,…), Maximum Contact Current (10 A, 20 A, 30 A,…) and Termination Style (PCB, Plug-In, Quick Connect,…) to name a few. You will be able to find the right automotive relay from several manufacturers that can be used as an SPDT relay, SPST relay, DPDT relay, non latching automotive relay, a quick connect auto relay, PCB relay, or for any other type of automotive relay.

Automotive Relays in Production Ready Packaging or R&D Quantities

If the quantity of automotive relays you need is significantly less than a full reel quantity, we offer many of our automotive relay products on special mini reels that are production ready, while avoiding unneeded surplus.

In addition, Future Electronics offers a unique bonded inventory program, designed to eliminate potential problems that can arise from an unpredictable supply of products containing raw metals and products with erratic or long lead times. Talk with your nearest Future branch and find out more on how you can avoid possible shortages.
