Our relays are tested and certified for a long life of smooth operation at any temperature and can handle 50,000+ cycles.

The AUTRA1000 is a SPDT (Single Pole, Double Throw) automotive relay. An SPDT relay is an electromagnetic switch consisting of:
Coil Terminals :: 85 and 86
Common Terminal :: 30
Normally Closed Terminal :: 87a
Normally Open Terminal :: 87

When the coil of an SPDT relay is at rest (not energized), the common terminal (30) and the normally closed terminal (87a) have continuity. When the coil is energized, the common terminal (30) and the normally open terminal (87) have continuity.

AutoLoc Relays are ideal for controlling any 12V device including Power Bear Claw® Latches, Shaved Door Kits, Power Suicide Hinges, Lambo Doors, Power Hinges, Power Windows, Power Windshield Wipers, Remote Keyless Entry, Linear Actuators, Power Tonneau Covers, Power Trunk and Hood, Air Compressors, Cooling Fans, Headlight Controllers, Rocker Switches plus more!

To make wiring your relay even easier, don’t forget a relay harness. AutoLoc recommends AUTRAS12. Make your installation a snap! Simply plug AutoLoc’s 40 amp relay into an AutoLoc Plug n Play relay harness socket and you’ve just saved yourself hours of wiring time.
