WOT Micro Switch Bracket 4500

The WOT Micro Switch Bracket 4500 is a critical component for drag racers and performance builders looking to automate nitrous oxide injection or other electronic triggers at full acceleration. Designed specifically for the high-performance Holley Dominator carburetor series, this bracket ensures that the nitrous system activates only when the throttle plates are fully open. This precise control prevents premature engine loading and potential intake backfires, making it an essential safety and performance upgrade for competitive racing environments.

Engineered by Allstar Performance, this kit includes both the micro switch and the mounting hardware required for a secure installation on 4500 series flanges. The lightweight design minimizes bulk while providing a rigid mounting point that resists vibration and heat-induced movement during intense engine operation. By utilizing a wide open throttle activation method, the switch eliminates the need for manual buttons, allowing drivers to focus entirely on steering and track conditions during high-speed passes.

This specific configuration is tailored for Holley Dominator carburetors, ensuring a perfect fit without the need for custom fabrication or extensive modifications to the linkage. Professional tuners and DIY mechanics will appreciate the straightforward bolt-on design that integrates seamlessly with existing fuel systems and nitrous solenoids. Whether you are looking to buy a reliable activation solution for a bracket racer or a dedicated strip machine, this micro switch kit offers the durability needed for consistent track performance.
