Handmade item to support play for children with disabilities. The battery box of a handheld fan has been modified and a BD adapter is set. 【How to Use】 ・Connect to your 3.5mm mono plug switch to turn ON-OFF. ・With a momentary switch (ON while pressed, OFF when released), the fan will run and blow air as long as the button is pressed. ・With an alternate switch (ON when pressed, locked, and OFF when pressed again to unlock), the fan will run continuously until pressed again. ・You can use it as a regular fan by removing the BD adapter. 【Reason for pre-setting the BD adapter】 ＊The BD adapter is inserted into the battery box and connected to a switch, allowing children to operate the switch themselves and move toys. ＊Commercially available ones are very fragile and can be easily disconnected if frequently inserted and removed from the battery box or pulled forcefully. ＊Some toys cannot accommodate a BD adapter. ＊Therefore, by modifying the battery box to accommodate the BD adapter and pre-setting it, we prevent damage to the BD adapter. Also, it may not conduct electricity properly depending on how it is set. ＊The BD adapter can be used for other toys, depending on the shape of the battery box. ＊Please be careful not to damage it when removing it. ＊If the wire breaks, it can be repaired by soldering. 【Specifications】 ・Fan: New. For 2 AA batteries. A hole has been made to pass the cord through to set the BD adapter. ・Batteries: Set of 2 ・BD Adapter: Copper plate diameter 10mm, cord length approx. 20cm, 3.5mm mono jack. 【Price and Shipping】 ・Shipped via either Rakuraku or Yu-Yu. ・We also sell switches and buzzers. ・We do not offer discounts. ・The box will be folded for shipping. #ChildrenWithDisabilities #Disabled #WelfareEquipment #Toys #Switch #Fan #PueruOn #TherapeuticEducation #Rehabilitation #AssistiveDevices
