Abstract: A switching apparatus provides switching modules, each of which can switch a voltage from an independent power source. Additionally, the switching apparatus provides a single output for independent sources, with the single output providing a power source for a load (e.g., server). In order to dissipate thermal energy, the switching apparatus includes a heatsink that is directly coupled to the switching modules. As a result of the connection between the heatsink and the switching modules, the switching apparatus can reduce the size of the heatsink as well the number of heatsinks. In this manner, the size, footprint, and amount of material of the switching apparatus is reduced, thus reducing the cost of the switching apparatus as well as increasing the ability to provide additional switching apparatuses in a volume, such as a cabinet.
