The AllSpark Micro Relay 12V 25A is a compact, high-quality normally open (N/O) 4-pin relay engineered for reliable switching in 12-volt DC electrical systems. Built with a built-in resistor for protection against voltage spikes and back-EMF, this relay safeguards sensitive electronics in your vehicle, caravan, or RV from costly damage. Rated at 25 amps continuous load capacity, it handles demanding accessories including lights, pumps, compressor fridges, winches, and auxiliary circuits with confidence. Its micro form factor makes it ideal for tight install spaces in caravans, camper trailers, 4WD canopies, and dual-battery setups where board space is at a premium.

Designed for Australian caravanners, 4WD adventurers, and DIY auto electricians, this relay is perfectly suited to upgrading or extending 12V accessory circuits on caravans, motorhomes, camper trailers, and off-road 4WD vehicles. Whether you're wiring up auxiliary lighting, a water pump, a compressor fridge circuit, or a dual-battery management system, the AllSpark micro relay delivers dependable switching performance on corrugated outback tracks or remote off-grid campsites. Its industry-standard 4-pin normally open configuration ensures straightforward integration with existing relay sockets and wiring harnesses — no specialist tools required.
