The BIG Candy Corn 2 accessibility switch uses highly sensitive proximity sensor technology for activation. Anytime the user is near or touching the activation surface, the BIG Candy Corn 2 will activate. Individuals with fine motor impairments or low vision prefer the BIG Candy Corn 2 over the LITTLE Candy Corn because it has an activation surface nearly twice the size.
Now powered by 2 AA batteries, the BIG Candy Corn 2 delivers twice the battery life of the original model, ensuring longer-lasting performance. When activated, an auditory beep and light provide feedback, which can be turned off if not needed.
