The Raindrop Switch is a cost-effective accessibility switch, an assistive device used by people with physical disabilities to control electronics (e.g. phones, computers, adapted toys,  game controls, etc.).

This particular switch is well-suited for use by a finger. It can be plugged into any standard 3.5 mm AT interface and even the Xbox Adaptive Controller. Users can arrange multiple switches in an array to get input from more than one finger. The switch can be mounted using adhesive on the rear surface.
