A vacuum cleaning tool adapter for vacuum cleaning systems having a control device incorporated within the adapter. The control device includes an electrical switch and may also include other circuit control devices. Also incorporated in the adapter is a connect-disconnect connector for mechanically interengaging the adapter with a hose assembly leading to the vacuum cleaner, which also provides electrical continuity from the adapter through current conducting reinforcing members in the hose assembly and into the vacuum cleaner. The adapter provides for electrically connecting the cleaning tool into the system, and the switch is used to turn the power on and off from the vacuum cleaner motor to the cleaning tool. An additional switch may also be located in the adapter for controlling the vacuum cleaner motor itself.
