I like the small ones too so I'll be curious to see how you guys come up with mounting them. The only comparable option I offer is the CPI Military switch but while it is low profile, it has a larger footprint than the little pushbutton which makes mounting an equal challenge with a bigger price tag.
Another plus to the little pushbutton units is the current rating. All the CPI and rotary style switches are only rated at 5 amps whereas RKO Motorsports advertises the pushbutton style at 15 amps making it ideal for anyone running dual 800's or larger.
I offer a few different bar options if dash space is not available but I also understand that quite a few guys don't like to run anything extra up the pole. Nothing quite like snapping a steering stud and risking taking out the steering cable, start stop and a bilge wire all in one shot.
