The motor runs to the right with the relay de energized as shown. 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.
How Do I Convert Dc Motor To Reverse With Spdt Switch
Dc motor reversing circuit with limit switches. Diode will be reversed biased. Diode will allow motor to go in reverse direction. It consists of a dpdt relay two spdt limit switches and 5 diodes. It doesnt start on its own you have to push a limit switch. It doesnt have interlocks or a stop button but it can all be added to it. Switch stops motor at limit and diode allows reversing of motor.
When the right limit sw is activated the relay coil is energized reversing the motor direction to the left. 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. The interlocks are specially important because if both relays are on it would be a short circuit. Below is a simple circuit that should do what you want. The circuit uses 2 relays 2 limit switches and a dc motor.
This is a minimal reversing circuit.
