Puff Switch is genuinely designed for GlassOuse, yet you can connect it to any kind of adapted device offering male to female 3.5mm jack plug in for external switch controls. Unlikely to regular sip and puff systems, Puff Switch uses an electronic module to do the clicks via puffs. Simply puff towards to the switch, and the built-in blow trigger will turn puff frequencies into signals to perform the clicks. The switch works with a coin size battery extremely easy to change and the battery life can go up to two months. The smart battery of Puff Switch will turn the switch off automatically in one hour if it is not used to enjoy a longer battery life while the switch also can be turned off manually via pressing the small button placed on the module.
