Agreed again. And if the voltage across the super-bright LED in the K300/600 is about 2.2V like it was in my K250, that is actually about 50% of the rating, so it should last even foreverer. Incidentally, the Mouser part number for the DPDT super-bright switch for the K300/600 would be 633-UB26KKW016G-JB. As SteveM has pointed out, be sure and connect the poles together, then connect the normally open throw contacts together, then connect the normally closed throw contacts together.
