Who Sells the Adjustable Brake Pressure Launch Control Switches??

I agree Chris.
They might be legal, at least for now, but they are just another way to aledgedly add some "delay" coming off the chip. Not much different than a long throw switch, the AXE or bleeder valves on solenoids.
I have not ran Stock for very long but it is more messed up than I thought it would be, thats for sure. Here I thought it was footbraking or clutching...what was I thinking? I should have known better with prize money at National Events reaching $15K with the right decals,

The adjustable pressure switch cannot and will not add delay.

This is because it is controlled by the brake pedal. If you set the switch-on pressure very low, the engine will be late coming off the two-step, but the car will have already started rolling, because you have released the brakes. So, it rolls out of the beam at 2300 rpm, or at whatever rpm the two-step is set.

This is why the old brake light switches from early Fords, for example, don't work very well. They are very sensitive to brake pressure, and the switch closes at something around 100 lbs.

On the other hand, a switch that closes at 800 lbs can be very uncomfortable to hold for any length of time. And maybe 500 lbs is comfortable for you, but not enough to hold the car at your chosen rpm.

The object is to get a quick release of the switch, before the wheels start rolling.

This is a bigger joke than the finger button. Bring back the finger button!
