Default Going with carb mounted kickdown switch location

I have been on a bracket shopping frenzy. I am replacing the throttle cable bracket because not only is it from an A body engine, I also hacked off the end that bolts to the intake manifold.

I am installing the correct coil bracket that attaches to the correct throttle cable bracket to get the coil off the firewall to where it belongs.

I am going to use a brake switch mounted in the kickdown switch bracket. It should work. There are other switches that are available that are built more robust and water resistant, but I will start off simple and dial in the brake switch first.

Thank you all for the assistance.

Unlikely.

What makes the kickdown switch "special" is that it has considerable travel AFTER the switch closes to engage the kickdown. That means the transmission kicks-down BEFORE you get to WFO. It is normally-open, closes with throttle travel when the throttle linkage pushes the switch plunger.

A typical brake switch is normally-closed, opens when the pedal arm pushes on the plunger.

Default I think I understand

I reread your post and deleted my questions.

Thanks for breaking it down.

Default I need a momentary switch

I need a momentary switch that is open and becomes closed while being pressed and held. Like a door bell? I must make certain that the switch is open until pressed

It escaped me that the brake pedal at rest depresses the switch. I probably would have rediscovered that fact after I bought and installed it without successful results.

Thank you for saving me from wasted money, wasted time, and wasted effort.
