Some of those diagrams are for 110V only- if you see T5 and T8 both connected to L1 or L2 at the same time, you should not use those on 220.
The others are similar to mine in that T4 is always connected to one of the lines. As I said before, that will work, but it is not as safe as I would like- you will need another disconnect for servicing (a plug would be sufficient).
The others also have needless amounts of wire going to the switch. There is no need to bring the star point (T2/T3 junction) and both T5 and T8 out to the switch. Yes, the motor nameplate says you have to switch T5 and T8 to reverse direction, and for 110 that is true. But for 220, one of T5/T8 is connected to the star point, and the other can be flipped between L1 and L2. My diagram does this, and saves you two pieces of wire from the motor to the switch.
Also note that none of these other drawings include a ground. Please be sure to ground the switch body and the motor casing.
