A power supply assembly which can drive a number of different devices at different voltages. Each of the switching systems includes switch devices supporting multiple local ports, and one gigabit high-speed port; each of the high-speed ports are full-duplex ports. The raceway balls of each row, in turn, surround and bear against a separate pivot ball. The low viscosity makes it possible to apply the hot melt adhesive at a high line speed and target application to only those areas requiring elastic performance.
