Unfortunately we're out of the V1 mechanical switches, and we do not plan on making anymore. The V1 has been discontinued since September, and we've still got replacement tact switches, resistors, and adapters left. You're more than welcome to shoot in your current tact switch so we can remove the resistor and turn it into the 3.7/6v option under our "Outside of Warranty" service terms. I'm sorry for the trouble!
