Start-stop-revese DC motor V2

After the comments from kiani in previouse version I connect things as he said. Although the previouse version will work, it can be dangerous if someone use it without reading the expalanation. ....... That is a circuit for starting, stoping and reversing the direction of rotation of DC motor. But, because there are not doubled switches in EC, we have to imagine that the switches shown act simultaneously. We have to imagine that there is a middle position for these swiches too - an OFF position. With other words we must accept that we have ONE doubled ON-OFF-ON switch. The two NC Push Buttons represent OFF-switches for the end positions of a door, window, carriage or some other thing the motor drives. So to start the motor we change the position of the switch to one of the ON-positions and to stop the motor we change position to tne middle OFF-position.
