Reverse motor control

Hi
I need to rotate a 12v motor in one direction permanently until a push button is pressed to reverse the motor.
Is this an easy task or does it involve a relay. Any help with wiring drawings would be great.
Thanks

How much current does the motor require?
How large is the motor?
What is the motor driving?
How long does it take to bring the motor and load to a stop?
You have to take into consideration the inertia of the system.

think it can be done whit 1 relay,
youl need a relay whit 2 switching sides,
this wil turn the engine around from the moment its activated so dont use it whit a heavy load on it or chance wil be that stuff wil rip apart,
also surge current wil apply drawing huge amps for braking any action its doing and then starting up the motor in the other direction

What do you mean by "permanently"?
Do you want to motor to run in one direction. Then while a switch is pressed, it will run in the other direction. When the switch is released, it will run in the original direction. Correct?

The complexity of your circuit will be much greater if you plan on using a 'momentary' push button. A button switch which latches, or stays in position until pushed again would simplify this request. One position would provide a path for forward rotation and the other position would provide a path for reverse operation connections.

Using a momentary switch that does not latch but makes contact only as long as it is pressed would require at least 2 relays with multiple poles to accomodate the required wiring changeovers
