Switch Single Pole with Spade Terminals

The QUICKCAR RACING PRODUCTS Switch Single Pole with Spade Terminals (part number 50-504) is a compact, weatherproof toggle switch engineered for race car electrical systems and performance vehicle builds. Rated at 25 amps and 12 volts, this switch delivers reliable on/off control with a durable weatherproof cover design that stands up to the harsh vibration and moisture exposure inherent in high-performance automotive environments. The single-pole configuration and spade terminal connectors make this switch ideal for brake system circuits, fuel pump relays, and other critical race-critical electrical functions where dependable switching is non-negotiable.

Spade terminals provide secure, tool-free connections to existing wiring harnesses, eliminating the need for solder joints in high-vibration applications where mechanical reliability matters. The 25-amp rating accommodates most auxiliary circuits in race cars, street rods, and off-road vehicles without undersizing the electrical load. The weatherproof cover protects the switch mechanism from dirt, fuel vapor, and moisture—critical in open cockpit race environments or vehicles exposed to water crossings and dusty terrain. At just 0.08 pounds with compact 3.5 x 0.8 x 4.5-inch dimensions, the switch installs easily in tight engine bays or dashboard spaces where real estate is limited.

This switch is purpose-built for builders and mechanics who need straightforward, proven electrical control in race cars, vintage hot rods, custom trucks, and marine-grade automotive applications. Whether you're wiring a three-wheel brake system, isolating a fuel pump circuit, or adding auxiliary lighting, a weatherproof single-pole switch with spade terminals eliminates corrosion concerns and provides tactile feedback that drivers depend on during high-stress driving conditions. QUICKCAR Racing Products' focus on motorsports-grade components makes this switch a trusted choice where electrical redundancy and durability directly impact safety and performance.
