Oversize Mushroom Button Micro Switch & Cord

The Oversize Mushroom Button Micro Switch & Cord by Biondo Racing Products is a heavy-duty momentary-contact push button designed for performance automotive applications where reliability and tactile feedback matter. Whether you're wiring a nitrous oxide system, engine kill switch, or custom ignition circuit, this oversized red button delivers the durability and electrical performance required in high-vibration engine bays and custom vehicles. The large mushroom head design provides intuitive operation even with gloved hands, making it ideal for race cars, hot rods, and serious track-focused builds where every control must function flawlessly.

Built to handle 15-amp loads at 12 or 16-volt systems, this micro switch delivers reliable momentary contact closure without chatter or false actuation under engine vibration. The spiraled cord design prevents tangling and routing issues in tight engine compartments, while the robust mushroom button geometry resists accidental activation and provides positive tactile confirmation on each press. The compact overall footprint (5.9 x 1.55 x 8.4 inches) allows flexible mounting in dash pods, steering columns, or floor-mounted locations common to street and race car builds.

Mechanics and fabricators rely on this switch for fuel pump cutoffs, auxiliary lighting circuits, and launch control wiring where momentary switching and automotive-grade reliability are non-negotiable. The 15-amp capacity suits most auxiliary circuits found in custom and modified vehicles, while the fixed cord eliminates splice points that can fail under thermal cycling. For anyone building a custom harness or upgrading OEM switch locations on a performance vehicle, the Oversize Mushroom Button Micro Switch & Cord offers industrial-grade switching in a form factor that works with automotive environments.
