# Relay - Car Relay-holder - URL: https://www.gt2i.ch/en/555/relay-car-relay-holder-competition ## Description GT2i is proud to present its range of electrical relays for cars and doors, electrical relays for motorsport. An element that provides the driver with a certain degree of safety, the electrical relay for cars flanges with the fuse and allows the opening and closing of the electronics circuit. We offer two types of electrical relays, the first with 4 pins and the second with 5 pins to meet the constraints of your circuit. Electrical relays allow you to safely control equipment with high consumption (fans, pumps, headlights, starters, etc.) without directly using your switches or calculators. They thus ensure fast and stable activation, while reducing the amount of wiring and increasing the lifespan of your components. Available in different powers (30A, 40A, 70A, etc.), with or without a support, our electrical relays are tested to withstand vibrations, extreme temperatures and humidity. Their proven reliability makes them an essential choice for any serious preparation project, whether for competition or technical restoration. Easy to integrate into your existing harnesses, the electrical relays are the perfect match for our relay holders, control boards and electrical accessories. Each model has been selected to offer a clear reaction, maximum protection and total compatibility with motorsport standards. GT2i supports tuners, amateurs and professionals with quality components, designed to last and perform in the most severe conditions. ## Subcategories ## Products - [Relay 12V 30/40 + Diode - 5B.](https://www.gt2i.ch/en/relay-car-relay-holder-competition/154548-relais-12v-30-40-diode-5b-3700660420497.html): CHF 4.80 -
