ABSTRACT:
A modular personal security device is described which includes a body having an interior battery receiving cavity, a handgrip and at least one module mounting surface whereby electronic and mechanical modules are mounted to the body. A first power supply circuit connects the battery receiving cavity with a first power switch connector on the body and a first power connector on the module mounting surface. A second power supply circuit connects the battery receiving cavity with a second power switch connector on the body and a second power connector on the module mounting surface. A multi-position trigger activated switch module is connected to the first power switch connector and the second power switch connector. Upon the trigger being pressed to one position the first power switch connector completes the first power supply circuit. By continuing to press the trigger to another position the second power switch connector completes the second power supply circuit. Upon the trigger further being pressed to subsequent positions both the first power supply and the second power supply circuits are completed thereby simultaneously supplying power to a modular unit mated with the first power connector and a modular unit mated with the second power connector. The device, as described, is particularly suited for coordinated sequential or simultaneous use of modular units providing multiple personal security features.
