The present invention relates to a buckle system including a male subassembly and female subassembly that are designed to mate with one another. The male subassembly also includes a printed circuit board (PCB) that may mate with an electrical connector within the female subassembly, thus completing a circuit for providing power to an electronic device when the subassemblies are mated. The male subassembly is connected to a cable portion that, when pulled with sufficient force, causes the male subassembly and its PCB to disengage the female subassembly and its electrical connector. The PCB and electrical connector may also be connected within standard side-release male and female subassemblies, respectively, for use in standard side-release buckles.
