ABSTRACT:
A personal protection device includes a generally dumbbell shaped hollow housing with an operable lever mounted in the central portion of the housing. An electrical circuit within the housing connects first and second switches to a power source and a speaker to produce a high decibel sound when both switches are closed. The first switch is connected to the lever and is maintained in an open position by gripping the housing and lever. The second switch is operable to the open position only upon operating a numeric code or other key lock system. Once the key lock switch has been closed, the speaker will be activated upon release of the lever on the dumbbell. A relay in the electrical circuit will bypass the first switch connected to the lever, once the relay has been activated, so that the speaker cannot be turned off except by opening the lockable second switch.
