Battery Interrupter for Adapted Toys, Size "AA" or "AAA"
Battery adaptors allow most toys with an on/off switch to be operated by a capability switch.  Simply place the interrupter between the battery and the spring within the battery compartment, and connect the interrupter to a capability switch.  Once switch is pressed, the interrupter will connect the batteries and the toy will perform the functions as if the toy has been turned on.
