How do I make a 12v motor turn in both ways?

Question

I have -+ 12v mains feed.
2 single action micro switch's (powered when held. 1each for left and right.)
The Motor has a -+ and the above action is its normal function.
I need to replace a Circuit board that had other function on it, some of which had failed.
I now need to make a wired circuit to replace it or pay £107.00 to turn the motor.
Thanks for your time in reading this.

Answer 2

I don't know if I understand your question right.

You want to be able to run the motor in both directions with 2 buttons. Pressing each button will make the motor turns in different direction. Am I correct?

If so, there is ways to do it. It would still cost you something but, not nearly as much as replacing the circuit board.

Here goes:
Change the switches to the "Double Pole Single Throw (DPST)" type.
This way, when you push one button, it will connect BOTH the positive and negative to the motor, let just say the correct direction way.
If you press the other button, it will then connect BOTH wiring in the reverse way.

Answer 3

Reverse the wires. May reverse the direction.

Answer 4

If it's not diode protected, you can reverse the feed wires.

Answer 5

turn it around before you startup
