I would like to add that the DNA200 pcb mounted buttons are wrapped and flowed under the actual button to a pad. If you try to do this with a radioshack iron you are going to lift the pads and have some issues. In other words, dont try this at home. I used TWO JBC CD-1BD Solder Irons at 720F with identical tips to touch all four pins on the pcb mounted switches and then carefully lifted them once the solder melted. My wife is hard to pursway in regards to buying the JBC Reflow station I wanted to use. John, check out the final product in a 1590A with 1000mah 60C Battery. https://instagram.com/p/5xDeB4AWCs/?taken-by=xevape[/QUOTE] Is there room to wire the tactile switch so that your index finger can hit the fire button?
