PREMIUM COCKPIT CONTROL & BACKLIGHTING
Bring sleek, high-visibility control to your onboard pneumatic accessories with the premium Kleinn Model 321A Illuminated Rocker Switch. Explicitly engineered to complement high-performance air horn and train horn setups, this heavy-duty toggle switch features a sharp, brilliant amber LED light profile. Built to mount perfectly into standard modern dashboard layouts, it functions as a visual reminder that you only run the absolute best—genuine Kleinn automotive air infrastructure hardware.
RECTANGULAR DROP-IN ARCHITECTURE
The Model 321A is designed for a clean, secure snap-fit installation, popping straight into standard 1 7/16" x 13/16" rectangular punch-outs on dashboards, center consoles, or custom driver panels. Outfitted with an independent backlight pin circuit, this rocker can be wired to illuminate dynamically when your headlights switch on, making it effortless to find in low-light off-road trail conditions. With a robust 20-amp load rating at 12 volts, it delivers highly consistent electrical cycle execution.
THE VERDICT: The definitive illuminated cockpit command toggle. The Model 321A blends clean amber lighting with rugged vehicle integration to ensure your high-output air accessories remain safely and instantly accessible on every drive.
🔴 PRO TIP: Keep your electrical circuits balanced and protected. When plumbing this manual trigger to a heavy-flow compressor loop, always route your high-current power path through an isolated 40-amp automotive relay like our fully sealed Kleinn Part #340 to insulate your dashboard switches from high-amperage spikes.
