Anyone ever rigged up a 2 step switch to run off your brake pedal?

Many of us in Stock run a pressure switch in Brake line rather than the
switch on the brake that we used to run years ago.

I would appreciate it if you would point me in the right direction for one of these switches.
Also what's to keep the 2 step from coming back on down the track when you apply the brakes?
