Need a reliable, high-power relay for your automotive or electrical project? This Gorniloxam set is a great value. You get three 40 Amp, 48V DC, 5-pin Single Pole Double Throw (SPDT) relays, plus three pre-wired socket harnesses. These are direct replacements for common types like JD-2912. The SPDT design lets you wire for normally open or normally closed operation. They're built to be waterproof, dustproof, and moisture-resistant, so they can handle tough conditions under the hood or outdoors. Perfect for car audio systems, light bars, winches, security systems, or any application that needs to switch a high-current circuit. The socket harnesses make installation plug-and-play – just connect your wires to the harness. A solid, affordable solution for DIYers and professionals alike.
