One throw actuates both poles. Example: that doubled air conditioner circuitbreaker. Add another position for each flapper "/ " and you have a double pole double throw. Periods .... were used to place flappers, which should connect to the O's below them. Graphical interface would be helpful. Throw = switching actions available to different circuit paths Pole = a power line connection to switch to the different paths.
