An apparatus for controlling use of electrically powered equipment includes an enclosure in which there is mounted an electrical connector receptacle which may be connected to a source of electrical power via its own power cable or plug blades. The enclosure is proportioned to receive the end of the electrical power cable or plug leads of one or more electrical power connectors of independently operated electrical devices. Plugging these devices into the electrical connector receptacle provides a direct, controlled connection to the power source. A locking device is provided on the exterior of the enclosure. This locking device could employ a variety of keyed and keyless lock designs. Disengaging the locking device unlocks the top enclosing lid of the enclosure to expose an electrical switch and a plurality of pins. When the electrical apparatus uses plug blades an attachment screw is also exposed to secure the electrical apparatus to the power source. The switch controls the flow of current from the power source to the independently operated electrical devices. The flow of current through the switch may be stopped with the top enclosing lid in the open or closed position. Simultaneously depressing the restraining pins allows the removal of a securable enclosure that is used to keep the electrical power connectors of independently operated electrical devices affixed to the invention. Preventing unauthorized operation as well as removal of independently operated electrical devices is obtained by maintaining the top enclosing lid in the closed position with the locking device engaged.
