alright thread closed. Thanks jayrob. Im looking into building some low powered pens for christmas presents. I need to look at costs and such.
 
you will have buisness from me inthe near future. Thanks.
PS-for the pcb board, is it diffuclt to wire up the momentary switch? Ive seen some of these buttons, but never actually used them before
 
When you get it adjusted right, just use a little glue...

Plus, the batteries will be pressing up to it's spring contact that you will solder on there.

The black plastic holder also gets a tiny dab of glue to position it.

There a little tricky until you get used to them. But not too bad if you have some basic building skills...
