NOS Nitrous Oxide Micro Switch Bracket

NOS Nitrous Oxide Micro Switch Brackets: Precision Activation for Serious Performance

When a nitrous system fires, there is no room for hesitation or inconsistency. The micro switch bracket may be one of the smallest components in a nitrous setup, but it plays an outsized role in ensuring the system activates at exactly the right moment — and only at the right moment. NOS (Nitrous Oxide Systems), the brand that essentially defined the modern nitrous industry, brings the same engineering discipline to their nitrous oxide micro switch brackets as they do to their full system kits and controllers.

Why the Micro Switch Bracket Matters

A micro switch bracket positions and secures the throttle-activated micro switch on the carburetor flange. Its job is to trigger the nitrous solenoids the instant the throttle reaches wide-open position — and to hold that switch rigidly in place so it responds the same way every single pass. A bracket that flexes, shifts, or suffers from poor fitment introduces variability into what should be a precise, repeatable event. NOS billet microswitch bracket kits eliminate flexing or bending, allowing for consistent activation of your nitrous system every time.

Billet Construction and Premium Finish

NOS billet microswitch and solenoid brackets are precision machined from solid 6061 billet aluminum and black anodized for corrosion resistance. The anodized finish not only resists the heat and chemical exposure of an underhood environment — it also gives the brackets a clean, professional appearance that complements any engine bay build. The billet brackets feature a laser-engraved NOS logo and a black anodized finish.

The billet construction saves weight while also eliminating flexing and bending. Most brackets have slotted mounting positions to allow more refined adjustability during installation. That adjustability is critical: getting the switch to trip at exactly the right throttle position — and staying there — can make a real difference in consistency at the track.

Carburetor-Specific and Universal Fitments

NOS offers micro switch bracket kits engineered for the most popular carburetor platforms in performance and racing applications. The NOS lineup includes a Billet Microswitch Bracket Kit for 4150 & 4150HP carburetor flanges, as well as a Billet Microswitch Bracket Kit for the 4500HP carburetor flange. NOS also released a billet microswitch bracket kit designed specifically for Holley's Gen 3 Dominator carburetors. For builders who want maximum flexibility, NOS also offers a universal micro switch and bracket assembly (part 15640NOS) that enables performance enthusiasts to activate solenoids, fuel pumps, and most anything else — and the micro throttle switch can be used as either the primary method of activating a nitrous system, or as a safety device in conjunction with another switch to prevent nitrous from coming on unless the vehicle is at WOT (wide open throttle).

Backed by Decades of Nitrous Expertise

NOS quickly became known for producing easy-to-install kits made from the highest quality material available. It is conceivable to say that nearly every significant performance milestone with nitrous was done with the NOS brand. That heritage carries directly into their bracket lineup — every detail, from material spec to slot geometry to finish quality, reflects the experience of a brand that has been at the center of nitrous performance since the late 1970s. Whether you are building a weekend bracket racer or a dedicated drag car, NOS micro switch brackets deliver the reliability and precision that performance-level activation demands.
