3 way switch help please

  1. Nov 14, 2012 #1
    For a rc car model, is there any way to reverse the current like a speed controller would but without one to be able to make the car reverse?
    I have been contemplating the option of three way switch but I'm not sure if it'll work. Any other helpful ideas?

    Welcome to PF;
    I'm sorry, you want to reverse the current through what exactly? RC Cars can have quite complicated circuits with current reversing and changing direction all over the place.

    If you reverse the current through the motor, for eg, the motor will go in reverse.
    The only way to stop this from making the car go backwards is to change gears.

    What is the problem you are trying to solve?
