Default Kedu HY56 safety switch

Hi guys,
Just bought this switch for an old table saw that has no switch at all. The motor is wired for 220v, but after searching the internet I cannot find directions for wiring it up that I can follow. Power cord has three wires, black,white and green(ground). Have included photos of the inside of the switch and the wire.
With three terminals, can I not just run my ground through the third terminal?
Very confused....have also included the so called wiring diagram....it shows the ground bypassing the switch entirely???
Any help and direction would be appreciated.

Thanks KBS2244,
So what you're saying is just the white to white black to black....then what exactly with the ground?

The ground is there to protect you. You need a direct path as shown back to your panel where the breakers are located, that way if something shorts out after the switch it will trip the breaker. It is possible without the direct ground cable a hot wire can come in contact with a metal part of the machine you are working with and energize the frame of the machine. Depending on the breaker it may not trip in this condition. if you were to touch the frame of the machine in this condition and a ground you would become in series with a live conductor. This is a very bad thing.

So run a ground from the machine and back to the breaker box every time.Do not switch it.

The green wire needs to be bolted to the frame of the machine, preferably with a star washer and ring terminal, sand the paint off to bright metal where the ring terminal contacts the machine. If you do not have a star washer use a split lock washer.

The ground would just hook directly to the saw ground terminal. You will hook white to white and black to black across two of the terminals on the back of the switch. One set will not be used. The switch has three sets for when it is used on Three Phase power, which you do not have. It will work with just the black and white hooked up. I probably would use the outer terminals, and leave the center ones unused.
