This is a homemade switch. It activates when the white stick is tilted, allowing you to operate toys and electrical appliances connected to the switch. It works when tilted in any direction, 360°. Compared to a stick switch using an Omron Z-15GNJ55-B, this one requires a more deliberate push. While more force is needed, you get a satisfying "click" feedback. Also, the main body vibrates when the toy is activated, providing tactile feedback to the user that they have "pressed" the switch. This machine is designed to support people with physical disabilities such as cerebral palsy and muscular dystrophy. It is intended for use in special needs education, nursing care, and therapeutic settings. It uses two AA batteries. (Batteries not included) A "Docchi mo Clip" (a type of clip for attaching to desks or wheelchairs) is also not included. I can include one if requested, but the cost of the clip and shipping will be added to the price, so it may be more economical for you to purchase one yourself. This is a handmade product, so there is no guarantee of long-term use or resistance to strong impacts. Please also be aware that there may be some scratches from the manufacturing process.
