Biondo Terminator Button Wiring

Dunno what people are doing, probably whatever they want until someone tells them they shouldn't, which is the usual NHRA procedure.

BTW, the way the rules are written it also makes it illegal to apply the transbrake and the linelock simultaneously since you can only have a single splice specifically for the two-step. Technically this is also true for stockers using a two-step, but I know of people who engage the linelock with the two step (at least they did before the rule change that required the button to be on the brake pedal).

Ok...I have got it figured out....turns out I was reading the microswitch current rating wrong. It states 10A / 125VAC,250VAC & .25A/250VDC .50A/125VDC

In a transbrake situation, the button is only activated for < 5 seconds which can handle 10Amps....so back to an easy circuit with no relays

Mine has been connected directly for two years with no issues. To do other wise is not legal. Wires direct from the trans brake to the button, all wiring on top of the carpet in plain view, etc.
