This is a homemade touch sensor switch. It activates when the user touches the metal tip, allowing them to operate toys and electrical appliances connected to the switch. The neck supporting the touch sensor is adjustable and can be bent to a certain degree, allowing for positioning that suits the user's needs. It operates with very little force and is designed to support individuals with cerebral palsy, muscular dystrophy, SMA, ALS, and other physical disabilities. It is intended for use in special needs education, caregiving, and therapeutic settings. It runs on three AA batteries, making it portable. (AA batteries are not included) Please note that this product may have minor scratches or imperfections from the manufacturing process. Also, as it is a handmade product, there is no guarantee of long-term durability or resistance to strong impacts. Thank you for your understanding.
