yeah that sounds about right to me, common usage for this type of switch would be for like a " forward /reverse switch" providing the rocker switch has a center position if not it should be wired after a power on/off. You must switch main power OFF to the equipment, then wait till the machine comes to a full STOP, then select your new direction, finally switch your main power back ON. Internally the motor is happy going one direction, it doesn't care which direction as long as its the same direction . It would be the same as driving down the freeway at 60 mph and throwing your car in reverse, (not a good idea). but something going to give (if your lucky it will just stall). OH YEAH one more thing "1 million Ohms won't kill you,.. its the watts
