uh no its not :P anyway...
first of all, that switch is unpractical unless u want to turn two sets of leds on seperately. in my diagram, flipping the switch one way would turn on the left leds and flipping the switch the other way would turn on the right leds.
but if u want to use that switch AND have all the leds turn on at the same time, then u will have to bridge the leds like so to make it so that if u flip the switch left or right all leds will turn on.
excuse my poorly drawn diagrams..
