My kid has a power wheel that we upgraded the motor from a 6v to a 12v recently. I upgraded all the wiring and the toggle switch to change the polarity of the dc motor (to switch from forward to reverse) failed.

That switch and the push button under the gas pedal were the only thing not upgraded, so here I am asking advice on how to wire it all up.

I found a diagram online for a Double Pole Double throw switch, which I understand, but where/how would I introduce the push button (gas pedal) so the motor is only activated when he pushes the gas?

The gas pedal is a simple 3 wire push button switch, if that helps.

Make sure the switch has adequate DIREC CURRENT ratings for the motor. Most switches are AC rated, and will not handle the same DC current

Put the PB in series with the positive wire, IE break the wire at 'C' and put the switch in that wire

I don't know a thing about those. You may need relay(s) if it draws much current

Much appreciated.

So the PB has 3 prongs. So one of them will go in series with C (battery power). Would the other two be Motor positive and motor negative?
 
there is probably a normally open and normally closed terminal on the switch. one pole will be common, one will be shorted, one will be open with the switch at rest. when pushed the normally open will close, and the normally closed will open. use a meter or a continuity tester to determine which two wires you will need.

You talking about the original foot switch? They are using "motor braking?"

Correct. Basically how it works is have the toggle switch that controls the polarity of the motor (whether you want to go forwards or backwards)
Then the foot pedal is a basic push button (3 prong switch) With it pushed all the way down the motor will spin at its fastest, halfway will spin slower, etc. When the pedal is at rest nothing happens.

I believe the 3 prongs are just like any other toggle (Power, Accessory, Ground) I am thinking about that correctly? And the accessory would be the motor positive?
 
Sorry don't know. Is the motor only two wire? If the speed selection is "all in the switch" and it's simply controlling power, it should only be two terminal. So I don't know.

Maybe I am not explaining it very well. Yes the motor is only two wires. I am thinking of the push button switch similar to an electric fan where you have a toggle controlling the power.

OK if the motor is only two wire, then that takes "multi speed" motor out of the equation. Not sure why the switch would need more than to, there must be a speed control resistor somewhere. Sorry, but without seeing and playing with one, I'm just guessing.

Maybe this will help?

Those are a little more complicated than my setup, but I get the idea. Thanks for your help. :)
