Ultra-Quick Mushroom Button Micro Switch

The Ultra-Quick Mushroom Button Micro Switch from Biondo Racing Products is a purpose-built momentary push-button switch engineered for automotive enthusiasts and professional fabricators who demand reliability in high-performance electrical systems. Designed for 12-volt and 16-volt applications, this compact switch excels in race car builds, custom vehicle wiring projects, and any motorsport application where space is at a premium and switch actuation must be instantaneous. The distinctive mushroom-head design provides intuitive tactile feedback and ergonomic operation, making it ideal for drivers who need quick access to auxiliary systems—fuel pumps, ignition cutoffs, lighting arrays, or data logging triggers—without fumbling for conventional toggle switches.

This micro switch is rated for 15 amps at both 12V and 16V, providing ample capacity for most auxiliary automotive circuits while maintaining fail-safe performance under sustained electrical load. The mushroom button geometry reduces accidental activation, a critical safety feature in race environments where vibration and driver input must remain distinct. The compact footprint—measuring just 4.1 inches in length, 1.1 inches in width, and 4.5 inches in overall height—allows seamless integration into tight dashboard mounting locations, custom console panels, or roll cage-mounted control clusters. The momentary action means contact closes only while pressure is applied, ideal for systems that should not remain energized without active input.

Mechanics and fabricators building dedicated race vehicles, road-course street cars, or off-road platforms will find this switch indispensable for fuel cell cutoff systems, secondary ignition circuits, and emergency electrical disconnects. Its dual-voltage rating (12V/16V compatibility) ensures compatibility with both traditional 12-volt automotive systems and specialty high-output charging setups common in pro-mod and bracket racing builds. Installation is straightforward—simple panel mounting with industry-standard wiring connections—and the robust construction withstands constant vibration, thermal cycling, and the electrical noise typical of high-RPM, high-amperage engine bays.
