    the attached pic is of a two channel RF transmitter and receiver that turns the motor in two directions. Button A rotates the motor clockwise while button B rotates the motor counterclockwise. How can I incorporate a switch or switches to rotate the motor in either direction. I'd like to operate the motor with switches and remotely.

    seems like a lot of blogs lately on reversal controllers


    Ok your remote is
    A toggle ON OFF and
    B toggle ON OFF and
    if A and B are both ON or both OFF, it stops, but both ON stops faster
    So I have it right?
    This is the safest to have momentary stop before changing direction. (to prevent twice the current arc and stress on mechanical plastic gears)

    If I understand, you want to remote change directions fast and have start stop fast?? with two buttons. ie. Change fwd +'ref inputs to Dirction and enable outputs?

    Do you have any electronic experience?

    Add detail to appocation andmmeed for speedy stop starts vs start, coast to a stop.

    Yes, you have it right, but A and B are both Momentary. I must hold the button for the motor to rotate, which is preferred.

    Yes, I want to be able to control the direction both remotely and non-remotely, all momentarily; no latching. Starting and stopping fast is not a concern.

    I have no electronic experience, this is an experiment I'm playing around with. Simply put, I want to momentarily control the direction of the motor both remotely and non-remotely.

    Okay. I finally got it to work the way I want. I had to add a DPDT relay. However, I do not know how to draw schematics or design PCB's. Is there a service available for me to send a picture of what I have in order to get this done? I'd like to have a few PCB's made...

    There is Eagle and Kicad for free PCCT design Pgm and I use either Itead or DirtyPCB for boards.

    I have a long way to go before I ,myself, could draw a proper schematic, even with software. Attached is my rookie attempt to relay meaning of this project. Any suggestions?

    Oops. I forgot to draw the positive and negative wires to the DPDT relay com pins.

    Yes. But it got a little out of focus, hence "do over". Sorry for the confusion.
