Abstract

A personal computer or similar machine has its ON-OFF switch locked by a security device consisting of a hasp 10, staple plate 12 and interposer 14. The hinge portion of hasp 10 is riveted to the rear panel of the computer adjacent to the ON-OFF switch (Fig. 1). Interposer 14 is welded or formed on the inside of the hasp. Staple plate 12 is riveted to the side panel of the computer's cover. When hasp 10 is moved into its locking position, staple 16 protrudes through slot 18 in hasp 10. A padlock, as shown in Fig. 2, is then placed through staple 16 and locked. Interposer 14 serves to block the switch paddle 20, preventing the possibility of prying the switch into the ON position with a thin tool. The security device, when in its locked position, also prevents the unauthorized removal of the computer's cover.
