ABSTRACT:
Power supplies which include sockets for supplying DC voltages as well as cables for supplying DC voltages to internal components of, for example, a computer are configured to prevent a user from connecting to an inappropriate DC voltage. The apparatus includes a special multiple din socket which provides a different voltage at each din of a subset of the dins, only one din of which is alive at a time. The apparatus includes a switch at each socket operative to select only a single din of a subset of dins at that socket. The illustrative apparatus includes several sockets, each one of which includes a different subset of dins selected by a switch, a single din at a time.
