2 step with footbrake automatic

Im wanting to install a 2 step in my car. I footbrake a 727 reverse pattern with Cheetah shifter.
I was originally thinking about a button on far right of brake pedal but didn't want to accidentally hit it at the end of the track.
I don't want a button on the steering wheel because that would be too much to launch.
Now Im thinking about using 2 micro switches. One on the brake pedal and one somehow attached to 1st gear on shifter. Any thoughts or ideas about that?

Maybe a momentary on switch tapped into the brake light switch?

Having done this in the past, I made a bracket that clamped to the brake pedal arm that the switch mounted to, so there was little risk of stepping on the switch at the other end of the track. It was a momentary type switch. What I found was the switch response was too slow, causing reaction time issues for me. I tried a couple of different switches, eventually I abandoned the 2 step idea and went to back to just foot braking. It just wasn't worth the trouble for me to sort it out.

Use a brake pressure switch plumbed into a brake line. Folk race cars sells 'em.

NHRA Stocker guys use the pressure switch in the brake line. If you search there are adjustable pressure switch's so you can fine tune it.

I have a Turbo Action shifter. I went to thr hardware store and got a larger diameter plastic roller that I replaced the smaller one on the shifter. Made a bracket for a Biondo switch. Wired it so my 2 step only works in first gear. My switch is on the far left of the pedal. Told my son to be careful if he needs to brake in 1st gear, always to the right side of the pedal, but otherwise will not be an issue. I do have a red light wired in also to show the 2 step is active. Simple, but has worked so far. Also I read that some brake pressure switches have 0-rings that are not compatible with brake fluid. How that is possible I don't know, but if you research o-ring material it explains it.
