"Adapting a tiny 1" Bluetooth switch for special needs has been a desire of mine for years. So I was glad when a manufacturer created one, using KickStarter funding, about a year ago. Now we have 3 sizes of Bluetooth switches to choose from!" RJ :)
Having the Bluetooth 'stuff' right inside the switch saves you from unwieldy cables and connections! I have been producing a 5" BT Super-Switch since 2010 (beat *that*, 'anyone'! ;-) . Then, last year I introduced my 3" version, the BT Small Switch. And now, a tiny one! :-)
It's sensitive and configurable to <space>, or <enter> or one of *many* other functions, such as a Home button (for newer iPads lacking Home buttons). PLEASE NOTE: This product is only for iPhone/iPad/Mac. Truth be told, Windows is *horrible* with Bluetooth and Android is not much better :-(
Works great with iOS or Android Accessibility!
My 'spin' on this item is adding my super-hook/loop tape (VERY strong and NOT commercially available) to the bottom, including my Vel-Strap with my special attachment method, and providing you with clear instructions for special needs usage.
