    Default forward / reverse motor wiring

    Hello all, I have a single phase 240V reversible motor which I am fitting onto a Radial Drill to raise and lower the workhead. I also have a forward (position1)- Off - Reverse (position 2) drum switch with terminals numbered from 1 to 12. I can get the motor to run clockwise and anti clockwise but my issue is wiring the drum switch for the cross over wiring.

    Found this diagram on google, the upper and lower diagrams is the wiring for my motor. The diagram on the right i assume is the drum switch but I cant work out which terminals on my drum switch to use.

    This is the terminal box on top of the motor
