Not at all - All he needs is two SPDT push buttons rated at least the rated
motor stall current. Wire the common termenals to the motor. Wire the NC
contacts to the common side of the power source (most likely - ), and the
N.O. contacts to the other side of the power source (most likely + ). Push
one, the motor goes one way, push the other, it goes the other way. Push
both the motor is shorted and it acts as an electric brake if the motor has
PM. Same for when they are both not pressed.
