It consists of a dpdt relay two spdt limit switches and 5 diodes. Switch stops motor at limit and diode allows reversing of motor.

Dc motor reversing circuit with limit switches. Diode will be reversed biased. The motor runs to the right with the relay de energized as shown. The circuit uses 2 relays 2 limit switches and a dc motor. It doesnt have interlocks or a stop button but it can all be added to it. Below is a simple circuit that should do what you want. Diode will allow motor to go in reverse direction.
The interlocks are specially important because if both relays are on it would be a short circuit. Wiring diagram of a dpdt connected motor plus two snap action switches for user control with limit stops. Normally upper and lower are closed but at limits one will open and shuts off motor. It would be nice to add a couple of additional switches to automatically stop the motor when it has gone too far but still allow the operator to return the motor to an allowed position. It doesnt start on its own you have to push a limit switch. When the right limit sw is activated the relay coil is energized reversing the motor direction to the left.
This is a minimal reversing circuit.
