Disclosed is a security locking device mounted on a body of a desk top computer. The locking device is key operated and allows the user to either disassemble the chassis or to turn on power to the appliance, depending on which direction and how far a key is rotated. The structure of the lock is simple as no microprocessor is used to operate the lock. Instead, a pair of contacting rods, positioned on a rotating shaft rotate onto contact plates to form electrical contact with the contacting plates, thus delivering power to the computer when the key is rotated to one of three possible positions. The computer chassis can be disassembled if the key is rotated to another of the three positions. Since the device is key operated, only authorized personnel can disassemble the device or electrically energize the device, thus protecting the computer hardware and software from theft.
