Two Step Brake Pedal Solutions?

From the 2016 Rule Book, in the in Section 10 Stock Cars

IGNITION, Automatic
Two-step permitted. Two-step must be foot-activated through
brake pedal, clutch pedal, or pressure switch. Hand release
prohibited. All wiring associated with the ignition system must be
fully visible, labeled, and traceable. See General Regulations 8:3.

And, from the General Regulations

.
8:3 IGNITION
Each car in competition must have a positive-action on/off switch,
capable of de-energizing the entire ignition system, in good
working order, located within easy reach of the driver.
“Momentary contact” switch prohibited. Magneto “kill button”-type
switches are prohibited.
All ignition systems and/or components wiring harnesses and
attachments must utilize those supplied by the ignition system
manufacturer. The wiring harness must be used in an unaltered
manner consistent with the manufacturer’s installation and
instruction books. All wiring associated with the ignition system
must be fully visible, labeled, and traceable.
All removable or pin-type timing devices are prohibited. Two-steps
or other rev limiters that are adjustable by thumbwheel, replaceable
chips, and the like may not be within the driver’s reach and will
preferably be located outside the driver compartment.
The use of any programmable multi-point rev limiter and/or a
rate-of-acceleration rpm limiter, either by themselves (e.g., MSD
7561 , MSD 7761 ) or integrated into the ignition system (e.g.,
MSD 7531 ), is prohibited in NHRA competition.

From all I read there, you are good to go with the micro switch on the shifter.

Electrical stuff is scattered throughout the book. This is what I found in General: 20.
ELECTRICAL/CONTROL: 8
8:2 DELAY BOXES/DEVICES

note: This is several paragraphs down)

Additional requirements for handicap start categories that prohibit delay devices:

"Wiring may consist of a single (i.e., “one” or “1”) continuous wire from a power source to a switch (or button), and a single continuous wire from the switch to the transbrake or line-loc solenoid. One splice (no quick-disconnect) is permitted from the two-step to the solenoid (i.e., between the switch and the solenoid). All line-loc/transbrake wiring before and after the switch must be separate from any other wiring and fully visible. Computer wiring, sensors, relays, and the like may not be wired to the solenoid wiring."

Not really sure this would apply to a two-step in a stick car because you are regulating the engine rpm, not the brake or trans circuit.

Dale,

The first line of this section, in General Regulations, makes this a non-issue for a Stock Eliminator car or any of the other classes listed.

8:2 DELAY BOXES/DEVICES
Prohibited in Top Fuel, Funny Car, Pro Stock, Pro Stock
Motorcycle, Top Alcohol Dragster, Top Alcohol Funny Car, Pro Mod,
Comp, Super Stock, and Stock;

I have a well known Super Stock racer, who helped me get my set up for last season, as I too was stumped as to what to as far as disabling the launch control at the top end.
He was impressed with what I finally came up with and it works like a charm.
