The Battery Adapter, model 720, is a switch adapter interface for single switch activation of any battery operated toy, tape recorder, or other device. Continuous pressure on the switch keeps the device running until the switch is released. The adapter can be used with the Switch Latch/Timer (see separate entry) to set action for a specified time period or to use switch hits for on and off. The disk end is inserted into the battery compartment; the other end plugs into any switch with a standard 1/8-inch mini plug.
