Like the configuration above, the switch, when moved in either direction, applies both power and ground directly to motor legs  without the use of any relays. Except, at the switch in this case, both motor legs rest at ground . Therefore it is only necessary to change the polarity of one motor leg to lock or unlock the vehicle.
