摘要： A device for controlling the selective switching on and off of the supply of current to an electric appliance of a premises, particularly a hotel room, includes a door lock having a bolt and a keeper to be mounted in a door and a door frame of an entrance to the premises such that the bolt is movable between first and second locked positions extending into the keeper and an unlocked position withdrawn from the keeper. An electric circuit connects a source of electric current to the electric appliance, and the circuit includes a switch normally closed to allow current to be supplied from the source to the appliance and operable to be opened to interrupt the supply of current from the source to the appliance. The switch is disposed in the keeper. The door lock includes first key-actuated structure, operable only from the exterior of the door, for moving the bolt between the unlocked position and the first locked position, whereat the bolt extends into the keeper by an amount sufficient to open the switch and thereby interrupt the supply of current from the source to the appliance. The door lock additionally includes second key-actuated structure, operable only from the interior of the door, for moving the bolt between the unlocked position and the second locked position, whereat the bolt extends into the keeper by an amount sufficient to lock the door lock but insufficient to open the switch, such that the switch remains closed and current remains supplied from the source to the appliance.
