Relays control forward stop and reverse action and the motor cannot be switched from forward to reverse unless the stop switch is pressed first. Motor forward and reverse is a very common seen application in our daily life for example we can use dc motor to control garage door open and close gate extract and retract curtain up and down etc these all have one thing in common the dc motor movement in two directions.

Dc motor forward reverse using relay. In the above forward reverse dc motor using relay double pole double throw relay wiring diagram. And the second switch which is connected in the way of positive wire is used for switch onoff the motor. Dc motor reversing circuit using dpdt relay the direction of a dc motor can be controlled with the input polarity at the motor terminals. So here we are using a simple dpdt relay arrangement for polarity alternation. The train travels to the down limit switch and reverses. In the circuit the motor terminals are connected between the two common poles of the relay.
A dc motor reversing circuit using non latching push button switches. Two one way switches used. A switch is used to turn dc direct current motor forward and reverse. Automatic forward reverse a motor the following circuit allows a motor such as a train to travel in the forward direction until it hits the up limit switch. This sends a pulse to the latching relay to reverse the motor and ends the short pulse. Also read dpdt relay wiring diagram.
