The Switch Poser sticks to a smooth, flat surface, like a lap tray, or a smooth table. It also includes an adapter which sticks to nonsmooth surfaces (semi-permanently) and gives you a smooth, flat surface to attach the Switch Poser.
The front of the Poser, where you attach your switch, uses an extremely strong fastening material so that when you stick your switch to the Switch Poser, it stays.
You can adjust the Switch Poser to any angle, even vertically for those that use a lateral, sliding motion because they can't lift their hand/arm. This way, they can use the side of their hand/fist, and slide into the switch for activation.
