No no, I mean in between the button and anything else. Tim said that the switches have changed and that they don't have an internal resistor any more. I really don't wont to blow out the led in the switch.

Just to make life more complicated, how small of a main body piece could I fit this into? I don't intend to add any boards or drivers to it later, I'm actually just designing this one as a shoto blade, her sister will be the bigger of the two, with room with a good sound board once I am more experienced. Ideally I would like to get all of this into a 5" or 6" blade extension piece (and obviously get the illuminated switch hole service).
