  • Patent number: 4647735
    Abstract: An electrical security apparatus includes an enclosure in which there is mounted an electrical receptacle which may be connected to a source of electrical power via its own power cord and plug. The enclosure is proportioned to receive the end of the power cord and the power plug of independently operated electrical device by plugging it into the electrical receptacle which makes direct connection to the power source provided in the apparatus through its power cord and plug. A keylock, operated by a removable key, is provided on the exterior of the enclosure. In the first position, the keylock, operated by a removable key, allows the top panel of the enclosure to be opened and closed. In the second position, the keylock locks the top panel and prevents removal of the power plug of the independently operated electrical device therefrom. In the third position, the keylock operates a switch to allow current to flow from the power source to the independently operated electrical device.
